Current through Register Vol. 28, No. 4, October 1, 2024

Section 2201-5.0 - Delaware Coastal Management Program Policies

5.1 Wetlands Management

5.1.1 The productive public and private wetlands in the State shall be preserved and protected to prevent their despoliation and destruction consistent with the historic right of private ownership of lands. [7 Del.C. § 6602]

5.1.2 Activities in or adjacent to wetlands shall be conducted so as to minimize wetlands destruction or degradation, to preserve the natural and beneficial values of wetlands, and to protect the public interest therein. [7 Del.C. §§ 6602, 6603 (a)(2), 6119, 4001]

5.1.3 Each State agency shall minimize the adverse effects to freshwater wetlands and conserve and enhance the environmental values and functions of freshwater wetlands in carrying out the agency's responsibilities. [Delaware Executive Order 56, May 26, 1988]

5.1.4 Each State agency, to the extent permitted by law, shall avoid undertaking or providing financial assistance for construction located in freshwater wetlands which will substantially degrade or destroy for long or permanent duration the use and function of an altered area as a wetland environment, unless the head of the agency, through consultation with the DNREC, files written findings with DNREC that:

5.1.4.1 There is no reasonable alternative to such construction, and that the proposed action includes all practicable measures to minimize undesirable impacts to freshwater wetlands which may result from such use, or

5.1.4.2 The request is consistent with the procedures and provisions of the following paragraph. In making this finding the head of the agency and DNREC may take into account social, economic, environmental and other pertinent factors. [Delaware Executive Order 56, May 26, 1988]

5.1.5 Any requests for new authorizations, appropriations, or grants of State operating or capital funds, or for State loan assistance or guarantees shall indicate, based on best available information, if an action to be proposed will be located in or will adversely affect freshwater wetlands, whether the proposed action is in accord with Delaware Executive Order Number 56. [Delaware Executive Order 56, May 26, 1998]

5.1.6 When State-owned freshwater wetlands are proposed for lease, easement, right-of-way or disposal to non-State public or private parties, the State agency shall:

5.1.6.1 Attach restrictions appropriate to Delaware Executive Order Number 56 to the uses of properties by the grantee or purchaser and any successor, except where prohibited by law; or

5.1.6.2 Withhold such properties from disposal. [Delaware Executive Order 56, May 26, 1998]

5.1.7 Wetlands to be managed by the DNREC are those lands above the mean low water elevation any bank, marsh, swamp, meadow, flat or other low land subject to tidal action in the State, including those areas which are now or in this century have been connected to tidal waters, whose surface is at or below an elevation of 2 feet above local mean high water, and upon which may grow or is capable of growing obligate or facultative wetland vegetation and those lands not currently used for agricultural purposes containing 400 acres or more of contiguous nontidal swamp, bog, muck or marsh exclusive of narrow stream valleys where fresh water stands most, if not all, of the time due to high water table, which contribute significantly to ground water recharge, and which would require intensive artificial drainage using equipment such as production of agricultural crops. [7 Del.C. § 6603(h)]

5.1.8 The conservation and protection of non-tidal wetlands shall be given consideration in development of land acquisition plans and comprehensive land use development plans. [Delaware Executive Order 43, August 15, 1996; Delaware Executive Order 56, May 26, 1988; 22 Del.C. Ch. 7; 9 Del.C. §§ 2656, 4956, 6956]

5.1.9 Activities which may adversely affect wetlands shall require State approval pursuant to the policy statements below. The CMP, however, requires no such approval for the following activities: construction of foot bridges, duck blinds, wildlife nesting structures, boundary markers, or aids to navigation that do not prevent the ebb and flow of the tide; mosquito control activities authorized by the DNREC; and hunting, fishing, haying, trapping, and grazing of domestic animals. [7 Del.C. §§ 6604, 6606; 7 DE Admin. Code 7502 subsection 6.1.4]

5.1.10 In order to assure that any activity in the wetlands is appropriate, State approval shall be required prior to the initiation of such activities, except no such approval shall be required for the activities identified in policy statement number 5.1.9. The following factors shall be considered prior to such approval: the environmental impact of the proposed use; the number and type of supporting facilities required and their impact; the effect of the activity on neighboring land uses; the appropriate State and local comprehensive plans for the general area; the economic impact of the activity in terms of jobs, taxes generated, and land area required; and the aesthetic impact of the proposed activity. Alternative methods of construction shall also be considered prior to permit approval. [7 Del.C. § 6604 7 DE Admin. Code 7502]

5.1.11 The cumulative impact of individual projects shall be considered when evaluating the environmental impacts of a proposed activity in wetlands. [Delaware Executive Order 43, August 15, 1996]

5.1.12 No permit will be issued to:

5.1.12.1 Dredge any channel through the wetlands deeper than the existing depth or the control channel depth specified by the Corps of Engineers at the point of connection to the adjacent navigable waterway to which the dredge channel is directly connected. A lesser depth may be specified by the Secretary of the DNREC in furtherance of the purposes of the Act.

5.1.12.2 Dredge any channel through the wetlands that has only one outlet to navigable water through which the normal daily tide ebbs and flows unless the channel is equipped, by aerators or other means, to maintain the Water Quality Standards for Streams that are issued by the DNREC.

5.1.12.3 Dredge channels through wetlands with sides more nearly vertical than a slope that rises one foot vertically for each three feet of horizontal distance except where conditions of soil composition prevent slope stabilization, so that bulkheading must be used.

5.1.12.4 Utilize wetlands for any activity unless it:

5.1.12.4.1 Requires water access for the central purpose of the activity; and

5.1.12.4.2 Has no alternative on adjoining non-wetland property of the owner.

5.1.12.5 Building bulkheads on wetlands higher in elevation than the surface of the natural land. Navigational aids that do not prevent the ebb and flow of the tide may be higher. [7 DE Admin. Code 7502 Section 7.0 ]

5.2 Beach Management

5.2.1 The public and private beaches of the State shall be preserved, protected, and enhanced to mitigate beach erosion and to prevent their destruction and despoliation. [7 Del.C. §§ 6801, 6803, 6810]

5.2.2 Publicly owned beaches and shorelines shall be managed and maintained to assure adequate and continued public access to these areas within the carrying capacity of the resource. [7 Del.C. § 4701 (c)]

5.2.3 Beaches are the areas from the Delaware/Maryland line at Fenwick Island to the Old Marina Canal north of Pickering Beach, which extend from the Mean High Water line of the Atlantic Ocean and Delaware Bay seaward 2,500 feet, and landward 1,000 feet. [7 Del.C. § 6802 (1)]

5.2.4 No person shall, without first having obtained a permit or letter of approval from the Department, undertake any activity:

5.2.4.1 To construct, modify, repair or reconstruct any structures or facility on any beach seaward of the building line.

5.2.4.2 To alter, dig, mine, move, remove or deposit any substantial amount of beach or other materials, or cause the significant removal of vegetation, on any beach seaward of the building line which may affect the enhancement, preservation or protection of beaches. [7 Del.C. § 6805 (a)]

5.2.5 Construction activities landward of the building line on any beach, including construction of any structure or the alteration, digging, mining, moving, removal or deposition of any substantial amount of beach or other materials, shall be permitted only under a letter of approval from the DNREC. [7 Del.C. § 6805 (c)]

5.2.6 The Department shall grant or deny a permit or letter of approval required by Policies 5.2.4 and 5.2.5 in accordance with duly promulgated regulations. If any structure proposed to be built in whole or in part seaward of the building line could reasonably be reduced in size or otherwise altered in order to eliminate or diminish the amount of encroachment over the building line, the Department shall require such reduction or alteration as a condition of granting the permit or letter of approval. [7 Del.C. § 6805 (d)]

5.2.7 By definition, the Building Line means a line generally paralleling the coast, set forth on maps prepared by the DNREC with reference to the National Geodetic Vertical Datum (NGVD) and the Delaware State Plane Coordinate System, and based upon information provided by topographic surveys. The Building Line is located as follows:

5.2.7.1 Along beaches extending from the Delaware/Maryland line to the tip of Cape Henlopen - 100 feet landward of the adjusted seaward most 10-foot elevation contour above NGVD;

5.2.7.2 Along beaches extending from the tip of Cape Henlopen to the southernmost limit of Primehook Beach - 100 feet landward of the adjusted seaward most 7-foot elevation contour above NGVD;

5.2.7.3 Along beaches extending from the southernmost limit of Prime hook Beach to the Old Marina Canal north of Pickering Beach - 75 feet landward of the adjusted seaward most 7-foot elevation contour above NGVD; or

5.2.7.4 At the landward limits of the beach, as defined in the Regulations Governing Beach Protection and the Use of Beaches dated December 27, 1983, whichever is most seaward. [7 DE Admin. Code 5102 Section 1.0 ]

5.2.8 If a structure located seaward of the Building Line is completely destroyed, no person shall undertake any restoration or reconstruction of the destroyed structure before the DNREC issues the person a permit or letter of approval pursuant to the Regulations Governing Beach Protection and the Use of Beaches. [7 DE Admin. Code 5102 subsection 3.3.1]

5.2.9 All structures, devices and facilities existing now or in the future which are devoted to the enhancement, preservation and protection of beaches shall be managed by the Department of Natural Resources and Environmental Control. [7 Del.C. § 6803(b)]

5.2.10 No person shall commence or conduct, without a permit therefore from the DNREC, construction of any structure or facility on any beach seaward of the Building Line, the primary function of which is beach erosion control or shore protection including, but not limited to, groins, jetties, seawalls, revetments, dikes, bulkheads, and beach nourishment; except that ordinary dune maintenance, as determined by the DNREC, including the proper installation of sand fence and the planting and fertilization of stabilizing vegetation, shall not require a permit. [7 DE Admin. Code 5102 subsection 4.3.1]

5.2.11 No person shall commence or conduct without a permit therefore from the DNREC, construction seaward of the Building Line, of any pipeline, dock, pier, wharf, ramp or other harbor work. [7 DE Admin. Code 5102 subsection 4.4.1]

5.2.12 If a structure is to be either constructed or reconstructed following the complete destruction of the original structure, and such a structure does not have to be located seaward of the Building Line in order to achieve its intended purpose, then such a structure shall be required to be located entirely landward of the Building Line. However, if the DNREC determines that there is inadequate space available entirely landward of the Building Line for the construction or reconstruction of a completely destroyed structure, said constructed or reconstructed structure shall be physically located as far landward as possible on the parcel of real property in question, taking into consideration all federal, state, and local laws, rules, regulations, and zoning and building ordinances. [7 DE Admin. Code 5102 subsection 3.4.1]

5.2.13 The following activities are prohibited:

5.2.13.1 The operation of any motorized vehicle or machine on, over or across the primary dune on any State-owned beach except at those locations specified by the Department for such use;

5.2.13.2 Pedestrian traffic on, over or across the primary dune on any State-owned beach except at those locations specified by the Department for such use;

5.2.13.3 The alteration, moving or removal of any facility, improvement or structure installed or maintained by the DNREC for enhancement, preservation or protection of any beach; and

5.2.13.4 The damaging, destruction or removal of any trees, shrubbery, beach grass or other vegetation growing on any State-owned or maintained beach seaward of the Building Line. [7 DE Admin. Code 5102 subsection 3.7.1]

5.2.14 State Action to reduce shoreline recession on private beaches may be taken, but only under the following conditions:

5.2.14.1 Where dangerous conditions exist on any privately owned beach which constitute an emergency;

5.2.14.2 In those instances where owners of private beaches allow free public use of such beaches in return for the assistance; or

5.2.14.3 Whenever two thirds or more of the property owners in the project area along the private beach have petitioned the Department to undertake the work. [7 Del.C. §§ 6801, 6804, 6810]

5.2.15 To the maximum extent possible the following system of priorities shall be utilized for the expenditure of limited beach preservation funds:

5.2.15.1 First priority shall be given to those beaches which suffer substantial and chronic erosion due to the presence of public navigation works;

5.2.15.2 Second priority shall be given to those intensely used, publicly owned beaches undergoing critical erosion. This category will be subdivided further according to the degree of public use, ease of access, rate of erosion, value of the area to the economy, and possible beneficial effects protection efforts may have on down drift Delaware beaches. Protection of private beach front structures will not be an overriding consideration;

5.2.15.3 Third priority shall be given to all remaining publicly owned recreational beaches;

5.2.15.4 Fourth priority shall be given to intensely used, publicly accessible private beaches;

5.2.15.5 Fifth priority shall be given to sparsely used, publicly accessible beaches; and

5.2.15.6 The last priority shall be given to privately owned, restricted beaches. In fact, all beach protection funds and State disaster-related reconstruction aid shall be restricted unless and until the beaches are opened to public use. [Delaware Executive Order 43, August 15, 1996]

5.2.16 All bonds issued for beach preservation projects shall not be issued for a period longer than the expected useful life of the work being financed. [Delaware Executive Order 43, August 15, 1996]

5.2.17 Efforts shall be made to utilize shoreline erosion control methods that best provide for the conservation of aquatic nearshore habitat, maintain water quality, and avoid other adverse environmental effects. Non-structural erosion control methods are preferred. However, structural erosion control measures may be allowed where it can be shown, through a review of site conditions and generally accepted engineering standards, that nonstructural measures would be ineffective in controlling erosion. [7 DE Admin. Code 7504 subsection 4.10.1.1]

5.3Coastal Waters Management

5.3.1 General

5.3.1.1 The development and utilization of the land and water resources of the State shall be regulated to ensure that water resources are employed for beneficial uses and not wasted, to protect beneficial uses of water resources, and to assure adequate water resources for the future. [7 Del.C. § 6001 (a)(2)(3)]

5.3.1.2 The water resources of the State shall be protected from pollution which may threaten the safety and health of the general public. [7 Del.C. §§ 6001 (a)(5), (c)(2)]

5.3.1.3 The coastal water resources of the State shall be protected and conserved to assure continued availability for public recreational purposes and for the conservation of aquatic life and wildlife. [7 Del.C. § 6001 (a)(4)]

5.3.1.4 It is the policy of the DNREC to maintain within its jurisdiction surface waters of the State of satisfactory quality consistent with public health and public recreation purposes, the propagation and protection of fish and aquatic life, and other beneficial uses of the water. [7 DE Admin. Code 7401 subsection 1.1]

5.3.1.5 The designated uses applicable to the various stream basins represent the categories of beneficial use of waters of the State which must be maintained and protected through application of appropriate criteria. Such uses shall include public water supply; industrial water supply; primary contact recreation involving any waterbased form of recreation, the practice of which has a high probability for total body immersion or ingestion of water such as swimming and water skiing; secondary contact recreation involving a water-based form of recreation, the practice of which has a low probability for total body immersion or ingestion of water such as wading, boating and fishing; maintenance, protection and propagation of fish, shellfish, aquatic life and wildlife preservation; agricultural wate 7 DE Admin. Code 7401 Sections 2.0 and 3.0 ]

5.3.1.6 Existing instream water uses and the level of water quality necessary to protect the existing uses shall be maintained and protected. Degradation of water quality in such a manner that results in reduced number, quality, or river or stream mileage of existing uses shall be prohibited. Degradation shall be defined for the purposes of this section as a statistically significant reduction, accounting for natural variations, in biological, chemical, or habitat quality as measured or predicted using appropriate assessment protocols. [7 DE Admin. Code 7401 subsection 5.1]

5.3.1.7 Where the quality of the waters exceeds levels necessary to support propagation of fish, shellfish, and wildlife and recreation in and on the water, that water quality shall be maintained and protected. In the case of E.R.E.S. waters, existing quality shall be maintained or enhanced. Limited degradation may be allowed if the DNREC finds, after review, that allowing lower water quality would result in a substantial net environmental or public health benefit and does not impede existing uses in the area in which the waters are located while allowing for full protection of existing uses. [7 DE Admin. Code 7401 subsections 5.2 and 5.6]

5.3.1.8 Where high quality waters constitute an outstanding national resource, such as waters of national parks and wildlife refuges, existing quality shall be maintained and protected. [7 DE Admin. Code 7401 subsection 5.3]

5.3.1.9 In those cases where potential water quality impairment associated with a thermal discharge is involved, the antidegradation policy and implementing method shall be consistent with Section 316 of the Water Quality Act of 1987. [7 DE Admin. Code 7401 subsection 5.4 ]

5.3.1.10 All surface waters of the State shall be free from substances that are attributable to wastes of industrial, municipal, agricultural or other human-induced origin. Examples include but are not limited to the following:

5.3.1.10.1 Floating debris, oil, grease, scum, foam, or other materials on the water surface that may create a nuisance condition, or that may in any water interfere with attainment and maintenance of designated uses of the water.

5.3.1.10.2 Settlable solids, sediments, sludge deposits, or suspended particles that may coat or cover submerged surfaces and create a nuisance condition, or that may in any way interfere with attainment and maintenance of designated uses of the water.

5.3.1.10.3 Any pollutants, including those of a thermal, toxic, corrosive, bacteriological, radiological, or other nature that may interfere with attainment and maintenance of designated uses of the water, may impart undesirable odors, tastes, or colors to the water or to aquatic life found therein, may endanger public health, or may result in dominance of nuisance species. [7 DE Admin. Code 7401 subsection 4.1]

5.3.1.11 Regulatory mixing zones shall not impinge upon areas of special importance, including but not limited to drinking water supply intakes, nursery areas for aquatic life or waterfowl, approved or conditional shellfish areas or heavily utilized primary contact recreation areas. Zones shall not be located in such a manner as to interfere with passage of fishes or other organisms. Shorehugging plumes should be avoided to the maximum extent practicable. In areas where multiple discharges are located in proximity, overlapping discharge plumes may occur. In such instances, the thermal mixing zone, which is not to exceed 25% of the cross-sectional area of the receiving water as measured from the point of discharge to the opposite shore, may be reduced to preclude acute toxicity in the overlap areas, or to ensure an adequate zone of passage for fish. [7 DE Admin. Code 7401 subsections 6.2 and 6.4]

5.3.1.12 Streams with a designated use of public water supply shall provide waters of acceptable quality for use for drinking, culinary or food processing purposes after application of approved treatment equivalent to coagulation, filtration, and disinfection (with additional treatment as necessary to remove naturally occurring impurities). Water shall be free from substances (except natural impurities) that, alone or in combination with other substrates, result in:

5.3.1.12.1 Unacceptable levels of taste or odor in the treated water;

5.3.1.12.2 Significant disruption of the treatment processes at the treatment facility; or

5.3.1.12.3 Concentrations of toxic substances in the treated water that may be harmful to human health. [7 DE Admin. Code 7401 subsection 4.2]

5.3.1.13 Designated exceptional recreational or ecological significance (ERES) waters shall be accorded a level of protection and monitoring in excess of that provided most other waters of the State. These waters are recognized as special natural assets of the State, and must be protected and enhanced for the benefit of present and future generations of Delawareans. [7 DE Admin. Code 7401 subsection 5.6 .1.1]

5.3.1.14 ERES waters shall be restored, to the maximum extent practicable, to their natural condition. To this end, the DNREC shall, through adoption of a pollution control strategy for each ERES stream basin, take appropriate action to cause the systematic control, reduction, or removal of existing pollution sources, and the diversion of new pollution sources, away from ERES waters. [7 DE Admin. Code 7401 subsection 5.6.1.2]

5.3.1.15 The discharge of oil from a vessel, truck, pipeline, storage, tank or tank car which causes or poses a threat of making a film on, emulsion in or sludge beneath the waters of the State or its shoreline shall be prohibited. [7 Del.C. §§ 6203, 6202 (7)(5)(9)]

5.3.1.16 At a minimum, any discharge of liquid waste - sewage, industrial waste or other waste to State waters shall be subject to effluent limitations, discharge requirements and any alternate effluent control strategy that reflect a practicable level of pollutant removal technology. For the purposes of this section, a practicable level of pollutant removal technology is defined as the application of "best" treatment technology, control measures and practices, including pollution prevention, available to prevent, manage, reduce or remove pollutants taking into account the cost of applying such technology, control measures or practices in relation to the effluent reduction benefits to be achieved, the age of equipment and facilities involved, the process(es) employed, the engineering aspects of applying the various types of control, process changes, pollution prevention measures, non-water quality impacts (e.g. energy requirements) and other factors deemed appropriate. For the parameters, BOD5 (5-day biochemical oxygen demand) and suspended solids, the degree of removal reflecting an application of a practicable level of pollutant removal technology shall be at least 85% of the BOD5 and suspended solids contained in the influent to the treatment works or prior to application of the removal technology, control measures or practices. For discharges of sewage to State waters, a practicable level of pollutant removal technology shall be secondary treatment and disinfection.

5.3.1.16.1 No person shall cause or permit any discharge of liquid waste to the Delaware River, the Delaware Bay, or Atlantic Ocean except liquid waste which has received at least secondary treatment and disinfection.

5.3.1.16.2 No person shall cause or permit discharge of liquid waste to a lake or a pond or any tributary thereof, except liquid waste which has received at least secondary treatment, filtration, nutrient removal and disinfection.

5.3.1.16.3 No person shall cause or permit any discharge of liquid waste to the Little Assawoman Bay, Indian River Bay, or to Rehoboth Bay, including any tributaries to those waterbodies, except liquid waste which has received at least secondary treatment, filtration, and disinfection.

5.3.1.16.4 No person shall cause or permit any discharge of liquid waste to a stream, tidal or non-tidal, except liquid waste which has received at least secondary treatment, filtration, and disinfection. This subsection shall not govern discharge into the Delaware River, the Delaware Bay or the Atlantic Ocean, which shall be governed by subsection 5.3.1.16.1. For existing facilities, filtration may not be required if the existing facility has demonstrated the ability to continuously meet secondary treatment levels. [7 DE Admin. Code 7201 subsections 7.1 and 7.2]

5.3.1.17 In the event that Delaware Surface Water Quality Standards are not achieved through application of the technology based requirements, additional effluent limitations and treatment requirements shall be imposed to assure compliance with the Surface Water Quality Standards. Such additional effluent limitations and treatment requirements must control all pollutants or pollutant parameters which the DNREC determines are or may be discharged at a level which will cause, have the reasonable potential to cause or significantly contribute to an excursion of any numerical or narrative water quality criterion contained within Delaware's Surface Water Quality Standards. The need for additional effluent limitations and treatment requirements shall be based upon the results of chemical and/or biological tests in conjunction with studies or analyses designed to assess the potential of the discharge to cause or contribute to in-stream excursions of Delaware's Surface Water Quality Standards. [7 DE Admin. Code 7201 subsection 8.1]

5.3.1.18 Where conflicts develop between stated surface water uses, stream criteria, or discharge criteria, designated uses for each segment shall be paramount in determining the required stream criteria, which, in turn, shall be the basis of specific discharge limits or other necessary controls. [7 DE Admin. Code 7401 subsection 1.2]

5.3.1.19 No person shall, without first having obtained a permit from the Delaware Department of Natural Resources, undertake any activity:

5.3.1.19.1 In a way which may cause or contribute to the discharge of an air contaminant;

5.3.1.19.2 In a way which may cause or contribute to the discharge of a pollutant into any surface or ground water;

5.3.1.19.3 In a way which may cause or contribute to withdrawal of ground water or surface water or both;

5.3.1.19.4 In a way which may cause or contribute to the collection, transportation, storage, processing or disposal of solid wastes, regardless of the geographic origin or source of such solid wastes;

5.3.1.19.5 To construct, maintain or operate a pipeline system including any appurtenances such as a storage tank or pump station;

5.3.1.19.6 To construct any water facility; or

5.3.1.19.7 To plan or construct any highway corridor which may cause or contribute to the discharge of an air contaminant or discharge of pollutants into any surface or ground water. [7 Del.C. § 6003 (a)]

5.3.1.20 No person shall, without first having obtained a permit from the Delaware Department of Natural Resources and Environmental Control, construct, install, replace, modify or use any equipment or device or other article:

5.3.1.20.1 Which may cause or contribute to the discharge of an air contaminant;

5.3.1.20.2 Which may cause or contribute to the discharge of a pollutant into any surface or groundwater;

5.3.1.20.3 Which is intended to prevent or control the emission of air contaminants into the atmosphere or pollutants into surface or groundwaters;

5.3.1.20.4 Which is intended to withdraw ground water or surface water for treatment and supply; or

5.3.1.20.5 for disposal of solid waste. [7 Del.C. § 6003 (b)]

5.3.1.21 Regulatory variances for the activities identified in the preceding policy statement may be granted pursuant to 7 Del.C. § 6011 if all of the following conditions exist in the opinion of the Secretary of the Delaware Department of Natural Resources and Environmental Control:

5.3.1.21.1 Good faith efforts have been made to comply with these policies;

5.3.1.21.2 The cost of compliance is disproportionately high with respect to the benefits which would be bestowed by compliance, or the necessary technology is unavailable;

5.3.1.21.3 Available alternative operating procedures or interim control measures are being or will be used to reduce adverse impacts; and

5.3.1.21.4 The activities are necessary to the national security or to the lives, health, or welfare of the occupants of Delaware. [7 Del.C. § 6011(b)]

5.3.1.22 No permit for the activities identified above shall be granted unless the activities are consistent with county and municipal zoning regulations. [7 Del.C. § 6003(c)(1)]

5.3.1.23 No person or entity shall commence construction, replacement, or operation of any of the following without first having obtained a permit from DNREC:

5.3.1.23.1 Sewer;

5.3.1.23.2 Any liquid waste collection or conveyance facilities such as waste water pump stations and force mains;

5.3.1.23.3 Liquid waste treatment facilities;

5.3.1.23.4 Any surface impoundment for liquid waste or

5.3.1.23.5 Any bulk storage, bulk transfer or pipeline facility. [7 DE Admin. Code 7201 Section 2.0 and subsection 4.2 ]

5.3.1.24 No person shall construct, install, modify, rehabilitate, or replace an on-site wastewater treatment and disposal system or construct or place any dwelling, building, mobile home, manufactured home or other structure capable of discharging wastewater on-site unless such person has a valid license and permit issued by the DNREC. [7 DE Admin. Code 7101 subsection 3.31.1]

5.3.1.25 No person shall cause or permit to be discharged, thrown, or dumped into any waters or any drainage ditch in the State any garbage, refuse, dead animal, poultry, trash, carton, bottle, container, box, lumber, timber, paper, or light material or other solid waste. [7 DE Admin. Code 7201 subsection 3.2.6]

5.3.1.26 No person or entity shall:

5.3.1.26.1 Engage in the drilling, boring, coring, driving, digging, construction, installation, removal, or repair of a water well or water test well, except as or under the supervision of a licensed water well contractor;

5.3.1.26.2 Construct, repair, install or replace any part of a septic tank system except by or under the supervision of a licensed septic tank installer; or

5.3.1.26.3 Operate any liquid waste treatment system without a licensed liquid waste treatment plant operator.

5.3.1.26.4 No permits or licenses shall be issued for these activities unless the DNREC finds that the applicant is prepared and willing to conduct such activities in a manner which is consistent with the CMP policies. [7 Del.C. § 6023; Delaware Executive Order 43, August 15, 1996]

5.3.1.27 The person who has caused the contamination of a person's drinking water supply by contaminant other than bacteria, viruses, nitrate or pesticides may be required to provide, at no cost to each person who has had his drinking water supply contaminated, an interim water supply that is of a quality and quantity to meet said person's needs as shall be determined by the Secretary of DNREC, in addition to the dates on which the interim water supply shall commence and be terminated. [7 Del.C. § 6037]

[16 Del.C. § 1301]

5.3.1.30 Water delivered to every consumer by any public water supplier shall be so protected by natural means, by proper constructions or by treatment so as maintain or increase water quality above the level determined to be safe and not to negatively impact users of water from such systems, either directly or indirectly. [16 DE Admin. Code 4462 subsection 3.3]

5.3.1.31 After July 1, 1991, unless a particular activity is exempted by these regulations, a person may not disturb land without an approved sediment and stormwater management plan from the appropriate plan approval agency. [Delaware Sediment and Stormwater Regulations, Section 8(1), amended April 11, 2005]

5.3.1.32 The following activities are exempt from both sediment control and stormwater management requirements:

5.3.1.32.1 Agricultural land management practices, unless the local Conservation District or the DNREC determines that the land requires a new or updated soil and water conservation plan, and the owner or operator of the land has refused either to apply to a Conservation District for the development of such a plan, or to implement a plan developed by a Conservation District;

5.3.1.32.2 Developments or construction that disturbs less than 5,000 square feet.

5.3.1.32.3 Land development activities which are regulated under specific State or federal laws which provide for managing sediment control and stormwater runoff, such as specific permits required under the National Pollutant Discharge Elimination System (NPDES) when discharges are a combination of stormwater and industrial or domestic wastewater.

5.3.1.32.4 Projects which are emergency in nature that are necessary to protect life or property such as bridges, culvert, or pipe repairs and above ground or underground electric and gas utilities or public utility restoration; and

5.3.1.32.5 Qualifying commercial forest harvesting operations. [Delaware Sediment and Stormwater Regulations, subsection 3.1 amended April 11, 2005]

5.3.1.33 A project may be eligible for a waiver of stormwater management for both quantitative and qualitative control if the applicant can demonstrate that:

5.3.1.33.1 The proposed project will return the disturbed area to a pre-development runoff condition and the pre-development land use is unchanged at the conclusion of the project; or

5.3.1.33.2 The proposed project consists of a linear disturbance of less than ten (10) feet in width; or

5.3.1.33.3 The project is for an individual residential detached unit or agricultural structure, and the total disturbed area of the site is less than one acre; or

5.3.1.33.4 The proposed project is for agricultural structures in locations included in current soil and water conservation plans that have been approved by the appropriate Conservation District. [Delaware Sediment and Stormwater Regulations, subsection 3.2.1, amended April 11, 2005]

5.3.1.34 All sediment and stormwater management plans shall be designed to implement water quality control measures to minimize, to the maximum extent possible, degradation of downstream water quality and habitat. Unless a particular activity is exempt, no person may disturb land without an approved sediment and stormwater management plan. [Delaware Sediment and Stormwater Regulations, subsection 10.2.2, amended April 11, 2005]

5.3.1.35 Water quantity control is an integral component of overall stormwater management. Control of peak discharges will, to some extent, prevent increases in flooding. The following design criteria for peak flow control are established for water quantity control purposes, unless a waiver is granted based on a case-by-case basis:

5.3.1.35.1 Projects in New Castle County that are located north of the Chesapeake and Delaware Canal shall not exceed the post-development peak discharge for the 2, 10, and 100 year frequency storm events at the pre-development peak discharge rates for the 2, 10, and 100 year frequency storm events.

5.3.1.35.2 Projects in New Castle County that are located south of the Chesapeake and Delaware Canal, Kent County, and Sussex County shall not exceed the post-development peak discharge for the 2 and 10 year frequency storm events at the pre-development peak discharge rates for the 2 and 10 year frequency storm events.

5.3.1.35.3 Watersheds, other than Designated Watersheds or subwatersheds that have well documented water quantity problems may have more stringent or modified design criteria that are responsive to the specific needs of that watershed. Modified criteria for that watershed must receive Departmental approval, and all projects reviewed and approved by the appropriate plan approval agency shall meet or exceed the modified criteria. Proposed modification of criteria for a watershed shall be subject to public review and comment prior to implementation. [Delaware Sediment and Stormwater Regulations, subsection 10.3.4, amended April 11, 2005]

5.3.1.36 Water quality control is also an integral component of stormwater management. Control of water quality on-site will prevent further degradation of downstream water quality. The following design criteria are established for water quality protection unless a waiver or variance is granted on a case-by-case basis.

5.3.1.36.1 In general, the preferred option for water quality protection shall be those practices collectively referred to as "Green Technology BMP's". Other practices shall be considered only after preferred practices have been eliminated for engineering or hardship reasons as approved by the appropriate plan approval agency.

5.3.1.36.2 Water quality be designed to manage the rate and volume of flow from the 2.0" NRCS Type II rainfall event, up to a maximum of 1.0" and

5.3.1.36.3 Alternative stormwater quality practices may be acceptable to the Department and/or the plan approval agency if the removal efficiency for suspended solids meets or exceeds 80% as demonstrated by scientifically independent evaluation and monitoring performance data,

5.3.1.36.4 The Department and/or plan approval agency may require other acceptable stormwater practices if a receiving waterbody has been identified as impaired or designated with a specific pollutant reduction target.

5.3.1.36.5 Water quality practices may also be acceptable to the Department and/or the plan approval agency if they are designed to reduce pollutant loading from a specific post-development source. [Delaware Sediment and Stormwater Regulations, subsection 10.3.5(1)(2)(3)(4)(5), amended April 11, 2005]

5.3.2 Marinas

5.3.2.1 Marina owners/operators for marinas that are located in whole or in part on tidal waters of the State, and that provide dockage for vessels with a portable toilet(s) or Type III marine sanitation device(s) (MSD), shall provide convenient access, as determined by the DNREC, to an approved, fully operable and well maintained pumpout facility(ies) and/or dump station(s) for the removal of sewage from said vessels to a DNREC approved sewage disposal system.

5.3.2.1.1 Owners/operators may agree to pool resources for a single pumpout dump station with Departmental approval based on criteria of number and class of vessels, marina locations, cost per pumpout use, and ultimate method of sewage treatment and disposal (i.e. septic system or waste water treatment facility).

5.3.2.1.2 The owner/operator of any boat docking facility that is located in whole or in part on tidal waters of the State, and that provides dockage for a live-aboard vessel(s) with a Type III marine sanitation device(s), shall install and maintain at all times, in a fully operable condition, an approved dedicated pumpout facility at each live-aboard vessel slip for the purpose of removing sewage from the live-aboard vessel on a continuous or automatic, intermittent basis to a DNREC approved sewage disposal system.

5.3.2.1.3 Any discharge, by any means, of untreated or inadequately treated vessel sewage into or upon the waters of any marina, boat docking facility or tidal water of the State of Delaware is prohibited.

5.3.2.1.4 All vessels while on waters of the State of Delaware shall comply with 33 USC 1322, as amended February 4, 1987. [7 Del.C. § 6035 (a) -(b)(1, 2, 3, & 4)]

5.3.2.2 No person shall construct, install, modify, rehabilitate, or replace a marina unless such person has a valid marina permit issued by the DNREC [7 DE Admin. Code 7501 subsection 2.5.1]

5.3.2.3 It is the policy of DNREC to prevent degradation of the surface and groundwaters of the State which might result from any pollutant source, so that all existing water designated uses are maintained and protected. Marinas shall be permitted only if they do not cause a violation of established Delaware water quality regulations either within the marina, or in adjacent ambient waters which mix or are contacted by waters from the marina. To achieve this goal:

5.3.2.3.1 These regulations set forth rebuttable presumptions that:

5.3.2.3.1.1 Land-based alternatives for non-water dependent activities are available.

5.3.2.3.1.2 Alternatives that do not involve the use of State waters for storage of boats have less adverse impact on the aquatic environment, and

5.3.2.3.1.3 Alternatives that do not involve the use of State waters for storage of boats are available.

5.3.2.3.2 Marinas shall be designed to maximize flushing so as to prevent the possible accumulation of contaminants that could result in a violation of the Delaware Surface Water Quality Standards, and to meet the policy objectives as set forth above. [7 DE Admin. Code 7501 subsections 11.2.1, 11.2.1.1, 11.2.1.2, 11.2.3.4, 11.3.2.1 and 11.4.1.1]

5.3.2.4 It is the policy of the State to preserve and protect public and private wetlands and to prevent their despoliation and destruction consistent with the historic right of private ownership of lands. Therefore, the Department shall strictly regulate the location of marinas in wetlands. Marinas shall be limited to those sites where short and long-term adverse impacts to the biological, chemical, and physical integrity of wetlands and their functions have been avoided, and that unavoidable impacts have been minimized and can be compensated for. Before disturbance of wetlands shall be permitted, the applicant shall demonstrate that all practicable alternatives to avoiding wetland impacts have been thoroughly examined and the results of such examinations shall be provided to the DNREC. In all cases, the applicant shall demonstrate that the purchase of additional property to avoid the wetland impacts is impracticable. [7 DE Admin. Code 7501 subsections 11.3.4.2 and 11.3.4.3]

5.3.2.5 Measures must be taken to first avoid, and then minimize unavoidable impacts to shellfish resources. The following impacts of marina facilities on shellfish resources will be considered:

5.3.2.5.1 Impacts on the organisms themselves, including their ability to survive, grow and propagate, without regard to potential use by humans;

5.3.2.5.2 Impacts that do not adhere to strict environmental safeguards for water quality; and

5.3.2.5.3 Impacts on the public's ability to harvest and consume edible shellfish species based upon the shellfish growing area classification proposed by the Delaware Division of Public Health for the marina or marina alteration under consideration. [7 DE Admin. Code 7501 subsection 11.3.5]

5.3.2.6 Marinas shall not be permitted in areas that will result in the destruction of submerged aquatic vegetation beds without corresponding compensation measures as approved by the DNREC. [7 DE Admin. Code 7501 subsection 11.3.10.3.2]

5.3.2.7 Dredging shall be limited to the minimum dimensions necessary for the project and shall avoid sensitive areas such as wetlands, shellfish resources, and submerged aquatic vegetation. Delaware Surface Water Quality Standards must not be violated because of dredging operations, excluding whatever temporary and minimal turbidity is unavoidable when using sound dredging practices. Marinas shall only be located in areas which, in the determination of the Department, offer safe and convenient access to waters of navigable depth. Such locations tend to present maximum opportunities for flushing, with less danger of sedimentation than very shallow sites. Safe and convenient access will be determined on a case-by-case basis. Factors such as existing water depths, distance to existing channels and their depths, and tidal and wave action will be considered. [7 DE Admin. Code 7501 subsections 11.4.2.1 and 11.4.4.1]

5.3.2.8 Benthic resources are protected because of their importance in the food chain and their value as commercial and recreational food sources. The status of a benthic community must be assessed by the applicant using frequency, diversity, and abundance measures approved by the DNREC. The DNREC may modify this methodology as experience is gained in applying certain techniques in Delaware waters. The DNREC may require monitoring of the benthos as a permit condition. [3 7 DE Admin. Code 7501 subsection 11.3.7]

5.3.2.9 Construction of marinas shall not be permitted at sites that are recognized by the DNREC as critical habitats. "Critical Habitat" includes areas classified by the DNREC and serving an essential role in the maintenance of sensitive species. Areas may include unique aquatic or terrestrial ecosystems that support rare endangered or threatened plants and animals. Rare, endangered or threatened species are defined by both state and/or federal listings. [7 DE Admin. Code 7501 subsection 11.3.8 and 7 DE Admin. Code 7504 Section 1.0 ]

5.4 Subaqueous Lands and Coastal Strip Management

5.4.1 The "coastal zone", referred to in these policies as the "coastal strip", is defined as all that area of the State, whether land, water or subaqueous land between the territorial limits of Delaware in the Delaware River, Delaware Bay and Atlantic Ocean, and a line formed by certain Delaware highways and roads. [7 Del.C. § 7002]

5.4.2 The natural environment of the coastal strip shall be protected from the impacts of heavy industry and oil pollution for the purpose of recreation, tourism, fishing, crabbing, and gathering other marine life useful in food production. [7 Del.C. §§ 7001, 6201]

5.4.3 The need for protection of the natural environment in the coastal strip shall be balanced with the need for new industry in the State's coastal areas [7 Del.C. § 7001]

5.4.4 The location, extent and type of industrial development in the coastal strip that will result in the degradation of the Delaware's bays and coastal areas shall be controlled [7 Del.C. § 7001; Kreshtool v. Delmarva Power & Light Co., Delaware Super., 310 A. 2d 649(1973)]

5.4.5 The development and use of offshore oil, gas, and other mineral resources of the State shall be managed to make the maximum contribution to the public benefit and so as to balance their utilization, conservation, and protection [Delaware Oil, Gas and Mineral Exploration Regulations, 2.1. September, 1971]

5.4.6 New heavy industrial uses shall be prohibited in the coastal strip. Such uses are ones characteristically involving more than 20 acres, and characteristically employing smokestacks, tanks, distillation or reaction columns, chemical processing equipment or waste-treatment lagoons. Heavy industrial uses shall not only be defined by their physical characteristics, however, but also by their potential to pollute in the event of human error or equipment failure. Examples of heavy industry are oil refineries, basic steel manufacturing plants, basic cellulosic pulp-paper mills, and chemical plants such as petrochemical complexes. For purposes of this policy, public sewage treatment or recycling plants shall not be deemed heavy industrial uses. [7 Del.C. §§ 7002 (e), 7003; Kreshtool v. Delmarva Power & Light Co., Delaware Super., 310 A. 2d 649(1973)]

5.4.7 New manufacturing uses or the expansion of existing manufacturing uses shall be allowed in the coastal strip by permit only, although in no case shall new manufacturing uses be allowed in wetlands or where inconsistent with local zoning regulations. Manufacturing uses are ones which mechanically or chemically transform substances into new products, and characteristically employ power-driven machines and materials handling equipment. Manufacturing uses typically include establishments engaged in assembling components of manufactured products, provided the new products are not fixed improvements. [7 Del.C. § 7002(d)(e), 7004(a)]

5.4.8 The following factors shall be considered in passing on requests for permission to construct or operate a manufacturing use in the coastal strip:

5.4.8.1 Environmental impact, including but not limited to, probable air and water pollution likely to be generated by the proposed use under normal operating conditions, as well as during mechanical malfunction and human error; likely destruction of wetlands and flora and fauna; impact of site preparation on drainage of the area in question, especially as it relates to flood control; impact of site preparation and facility operations on land erosion; effect of site preparation and facility operations on the quality and quantity of surface, and subsurface water resources, such as the use of water for processing, cooling, effluent removal, and other purposes; in addition, but not limited to, the likelihood of generation of glare, heat, noise, vibration, radiation, electromagnetic interference and obnoxious odors.

5.4.8.2 Economic effect, including the number of jobs created and the income which will be generated by the wages and salaries of these jobs in relation to the amount of land required, and the amount of tax revenues potentially accruing to State and local government.

5.4.8.3 Aesthetic effect, such as impact on scenic beauty of the surrounding area.

5.4.8.4 Number and type of supporting facilities required and the impact of such facilities on all factors listed in this subsection.

5.4.8.5 Effect on neighboring land uses including, but not limited to, effect on public access to tidal waters, effect on recreational areas, and effect on adjacent residential and agricultural areas.

5.4.8.6 County and municipal comprehensive plans for the development and/or conservation of their areas of jurisdiction. [7 Del.C. § 7004(b)]

5.4.9 New offshore gas, liquid, or solid bulk product transfer facilities shall be prohibited in the coastal strip. Such facilities are docks or port facilities, whether artificial islands or attached to shore by any means, for the transfer of bulk quantities of any substance from vessel to onshore facility or vice versa. However, a docking facility or pier for a single industrial or manufacturing facility and docking facilities located in the City of Wilmington for the Port of Wilmington shall not be prohibited. [7 Del.C. §§ 7002 (f), 7003; Inf. Attorney General Opinion No. 65, October 22, 1974]

5.4.10 Offshore pipelines which transfer bulk quantities of gas, oil, or other liquids to terminals within the coastal strip shall be prohibited. Such pipelines generally shall be allowed if they transit the coastal strip and environmental safeguards are observed. However, if such pipelines represent a significant danger of pollution to the coastal strip or generate pressure for construction of industrial plants in the coastal strip, they shall be prohibited. [7 Del.C. §§ 7001, 7002, 7003; Inf. Attorney General Opinion No. 77-33, July 6, 1977]

5.4.11 A permit may be issued for geological, geophysical and seismic surveys, including the taking of cores and other samples, or the tide and submerged lands of this State. Such permits shall be nonexclusive and shall not give any preferential rights to any oil, gas and sulfur or other mineral lease. After consultation with those agencies of the State having an interest in the possible effects of the leasing, such rules and regulations deemed necessary to protect the fish, game, wildlife and natural resources of the State shall be included in the permit. Survey activities on any area determined to be an area where a lease should not be granted may be prohibited. The permit shall include conditions and payment proper to safeguard the interests of the State. [7 Del.C. §§ 6103, 6104]

5.4.12 No operations or activities shall be commenced on the drilling, deepening or plugging back of any offshore oil or gas wells located on underwater lands of Delaware without the permission of the State, and unless the activities are conducted in a manner which do not result in the degradation of the State's natural resources. [Delaware Oil, Gas and Mineral Exploration Regulations Numbers I-V, September 1971]

5.4.13 Easements for mineral exploration and exploitation underlying that part of the surface of the Atlantic shore owned by the state shall be permitted at such times and places as necessary to permit the extraction and transportation of oil, gas, sulfur or other minerals from State, federal or private lands, but permanent interference with the surface of the Atlantic shore shall be prohibited. [7 Del.C. § 6102 (d), 6118, 6119(a)]

5.4.14 Before offering tide and submerged lands for leasing for possible mineral development, or whenever any person files a written application with the Secretary of DNREC requesting that lands be offered for leasing, accompanying the same with the required fee, a public hearing shall be held. After the public hearing, it will be determined whether an invitation for bidding to lease the area under consideration would be in the public interest. Consideration shall be made as to whether a lease or leases of the area under consideration would:

5.4.14.1 Be detrimental to the health, safety, or welfare of persons residing in, owning real property or working in the neighborhood of such areas;

5.4.14.2 Interfere with the residential or recreation areas to an extent that would render such areas unfit for recreational or residential uses or unfit for park purposes;

5.4.14.3 Destroy, impair or interfere with the aesthetic and scenic values of the Delaware coast, or other affected area;

5.4.14.4 Create any air, water and other pollution;

5.4.14.5 Substantially endanger marine life or wildlife;

5.4.14.6 Substantially interfere with commerce or navigation; and

5.4.14.7 Protect State lands from drainage of oil, gas or other minerals or objectionable substances [7 Del.C. §§ 6107, 6108]

5.4.15 Avoidable pollution or avoidable contamination of the ocean and of the waters covering submerged lands, avoidable pollution or avoidable contamination of the beaches or land underlying the ocean or waters covering submerged lands, or any substantial impairment of and interference with the enjoyment and use thereof, including but not limited to bathing, boating, fishing, fish and wildlife production, and navigation, shall be prohibited and the lessee shall exercise a high degree of care to provide that no oil, tar, residuary product of oil or any refuse of any kind from any well or works shall be permitted to be deposited on or pass into the waters of the ocean, any bay or inlet thereof, or any other waters covering submerged lands; provided, however, that this policy does not apply to the deposit on, or passing into, such water or waters not containing any hydrocarbons or vegetable or animal matter. [7 Del.C. § 6119 (a)]

5.4.16 For the purposes of this section, "avoidable pollution" or "avoidable contamination" means pollution or contamination arising from:

5.4.16.1 The acts of omissions of the lessee or its officers, employees or agents; or

5.4.16.2 Events that could have been prevented by the lessee or its officers, employees or agents through the exercise of a high degree of care. [7 Del.C. § 6119(b)]

5.4.17 State subaqueous lands within the boundaries of Delaware constitute an important resource of the State and shall be protected against uses or changes which may impair the public interest in the use of tidal or nontidal waters. [7 Del.C. Ch. 72]

5.4.18 No person shall deposit material upon or remove or extract materials from, or construct, modify, repair or reconstruct, or occupy any structure or facility upon submerged lands or tidelands without first having obtained a permit, lease or letter of approval from the DNREC. Such permit, lease or letter of approval, if granted, may include reasonable conditions required in the judgment of the DNREC to protect the interest of the public. If it is determined that granting the permit, lease or approval will result in loss to the public of a substantial resource, the permittee may be required to take measures which will offset or mitigate the loss. [7 Del.C. § 7205]

5.4.19 The extent of jurisdictional authority over public or private subaqueous lands includes any activity in a navigable stream or waterbody, which have a hydrologic connection to natural waterbodies. "Activity" includes, but is not limited to, any human induced action, such as dredging, draining, filling, grading, bulkheading, mining, drilling, extraction of materials or excavation, or construction of any kind, including, but not limited to, construction of a boat ramp or slip, breakwater, residences, bridge, bulkhead, culvert, dam, derrick, deck, groin, jetty, lagoon, gabion, rip-rap, launching facility, marina, mooring facility, pier, seawall, walkway, or wharf. [7 DE Admin. Code 7504 Section 1.0 and subsection 2.2.1.1]

5.4.20 The following types of activities in, on, over, or under private subaqueous lands require a permit or letter of authorization from the DNREC:

5.4.21.11 New dredging activities of channels, ditches, dockage, or other waterways [7 DE Admin. Code 7504 subsection 2.4.2]

5.4.22 The DNREC shall consider the public interest in any proposed activity which might affect the use of subaqueous lands. These considerations include, but are not limited to, the following:

5.4.22.1 The value to the State or the public in retaining any interest in subaqueous lands which the applicant seeks to acquire, including the potential economic value of the interest.

5.4.22.2 The value to the State or the public in conveying any interest in subaqueous lands which the applicant seeks to acquire.

5.4.22.3 The potential effect on the public with respect to commerce, navigation, recreation, aesthetic enjoyment, natural resources and other uses of the subaqueous lands.

5.4.22.4 The extent to which any disruption of the public use of such lands is temporary or permanent.

5.4.22.5 The extent to which the applicant's primary objectives and purposes can be realized without the use of such lands (avoidance).

5.4.22.6 The extent to which the applicant's primary purpose and objectives can be realized by alternatives, i.e. minimize the scope or extent of an activity or project and its adverse impact.

5.4.22.7 Given the inability for avoidance or alternatives, the extent to which the applicant can employ mitigation measures to offset any losses incurred by the public.

5.4.22.8 The extent to which the public at large would benefit from the activity or project and the extent to which it would suffer detriment.

5.4.22.9 The extent to which the primary purpose of a project is water-dependent. [7 DE Admin. Code 7504 subsection 4.6 ]

5.4.23 The DNREC shall consider the impact on the environment, including but not limited to, the following:

5.4.23.1 Any impairment of water quality, either temporary or permanent, which may reasonably be expected to cause violation of the State Surface Water Quality Standards. This impairment may include violation of criteria or degradation of existing uses;

5.4.23.2 Any effect on shellfishing, finfishing, or other recreational activities and existing or designated water uses;

5.4.23.3 Any harm to aquatic or tidal vegetation, benthic organisms or other flora and fauna, and their habitats;

5.4.23.4 Any loss of natural aquatic habitat;

5.4.23.5 Any impairment of air quality either temporarily or permanently, including noise, odors, and hazardous chemicals;

5.4.23.6 The extent to which the proposed project may adversely impact natural surface and groundwater hydrology and sediment transport functions. [7 DE Admin. Code 7504 subsection 4.7.1]

5.4.24 The DNREC shall also consider the following to determine whether to approve the application:

5.4.24.1 The degree to which the project represents an encroachment on or otherwise interferes with public lands, waterways or surrounding private interests.

5.4.24.2 The degree to which the project incorporates sound engineering principles and appropriate materials of construction.

5.4.24.3 The degree to which the proposed project fits in with the surrounding structures, facilities, and uses of the subaqueous lands and uplands.

5.4.24.4 Whether the proposed activity complies with the State of Delaware's Surface Water Quality Standards both during construction and during subsequent operation or maintenance.

5.4.24.5 The degree to which the proposed project may adversely affect shellfish beds or finfish activity in the area. [7 DE Admin. Code 7504 subsection 4.7.5]

5.4.25 The following concerns for protecting water quality shall be specifically considered by the DNREC in evaluating applications for dredging projects:

5.4.25.1 All dredging is to be conducted in a manner consistent with sound conservation and water pollution control practices. Spoil and fill areas are to be properly diked to contain the dredged material and prevent its entrance into any surface water. Specific requirements for spoils retention may be specified by the DNREC in the approval, permit or license.

5.7.1 General

5.7.1.1 Local floodplain management programs shall be monitored and annually reviewed to determine if they are being administered properly and are achieving flood damage reduction objectives. Federal floodplain standards shall also be periodically reviewed as they apply to Delaware to determine if they are adequate to mitigate damage in the State's floodplains and to determine whether long and short-term adverse impacts associated with the activities within flood plains and support of flood plain development are being avoided to the extent possible. In the event that any of the above determinations indicate the need for remedial action, the aforementioned agency shall take whatever measures it deems appropriate to correct the situation. [Delaware Executive Order 43, August 15, 1996; Executive Order 48, February 27, 1978]

5.7.1.2 All State agencies shall participate in and comply with the requirements of the Federal Flood Insurance Program. [Delaware Executive Order 48, February 27, 1978; Delaware Executive Order 43, August 15, 1996]

5.7.1.3 State agencies shall to the maximum extent possible minimize the threat posed by flood hazards for the following activities:

5.7.1.3.1 The construction of state buildings, structures, roads or other facilities;

5.7.1.3.2 The administration of grant or loan programs involving such construction by other governmental entities or private parties;

This policy shall not apply to cutting operations of timber from land being cleared for reservoirs, military installations, agriculture, residential, ditch and utility right-of-ways, industrial sites, railroads or to cutting operations undertaken pursuant to a contract executed prior to January 1, 1989. [3 Del.C. § 1053(a)(b)]

5.9.1.4 No person shall cut or permit to be cut any pine or yellow-poplar tree or seedling required to be reserved for reseeding or planted under a reforestation plan or perform any act or permit any act to be performed which prevents reseeding or reforestation of any area in which a cutting operation has been conducted. [3 Del.C. § 1056]

5.9.2 Silviculture

5.9.2.1 Waters of the State shall be protected from sediment pollution resulting from silviculture activities. [3 Del.C. § 1071, 1073]

5.9.2.2 Special orders can be issued if the Forestry Administrator, or Forestry Administrator's designee, finds that any owner or operator is conducting any silvicultural activity in a manner which is causing or is likely to cause alteration of physical, chemical or biological properties of any State water, resulting from sediment deposition presenting an imminent and substantial danger to

5.9.2.2.1 The public health, safety, or welfare, or the health of animals, fish or aquatic life;

5.9.2.2.2 A public water supply; or

5.9.2.2.3 Recreational, commercial, industrial, agricultural or other reasonable uses. [3 Del.C. § 1073]

5.9.2.3 All open water bodies, perennial streams, intermittent streams with a well-defined channel, and streams that have been hydrologically modified by dredging or straightening shall have a Streamside Management Zone (SMZ), unless the property or a portion of the property is covered by an approved Delaware Seed Tree Law application and is located on slopes of less than three (3) percent. The minimum width for a SMZ is 50 feet from each side of qualifying streams. Within a SMZ, at least sixty (60) square feet of basal area per acre of trees well distributed throughout the area shall be retained, or at least sixty (60) percent of the overstory. [ 3 DE Admin.

5.9.3.2 All public and private entities whose actions may substantially affect agricultural lands in Delaware, or the agricultural productivity of such lands, shall consider the need to preserve and protect such lands prior to taking such actions, and should preserve and protect agricultural lands whenever practicable. State agencies shall protect and preserve agricultural lands to the maximum extent practical. [3 Del.C. Ch 9; Delaware Executive Order 42, August 15, 1996]

5.9.3.3 "Scattered" development should be limited through the consideration of alternative locations in growth zones, the availability of public services such as sewer and water systems, police and fire facilities, and costs for resulting infrastructure needs when planning for future growth and development. [9 Del.C. Ch 26 Subch II, Ch 49 Subch II, Ch 69 Subch II; Delaware Executive Order No. 43, August 15, 1996]

5.9.4 Tax Ditches

5.9.4.1 Tax ditch planning will be done on a watershed basis. A watershed area comprises all the land and water within the confines of a drainage divide and must follow hydrologic boundaries for engineering purposes. A watershed area may comprise the land and water of two or more minor drainageways that are separate tributaries to a stream, artificial waterway, lake, or tidal area. The watershed area considered for design must include all direct tributary drainageways and lands that contribute to flows in the planned channels. [Principle and Guidelines for Planning, Constructing, and Maintaining Drainage Ditches in the State of Delaware, section A, June 1995]

5.9.4.2 Channels proposed for cleanout should be limited to those which have reduced hydraulic capacity due to sediment, woody vegetation, and debris. Channels which do meet functional standards may be included in the tax ditch plan for future maintenance. Land use changes may have eliminated the need for reconstructing some channel segments. [Principle and Guidelines for Planning, Constructing, and Maintaining Drainage Ditches in the State of Delaware, section B, June 1995]

5.9.4.3 Environmental studies associated with tax ditch projects will concentrate primarily on impacts to wetlands, forestry and disruption of fish and wildlife resources. Most channel cleanout projects are small in scope and have limited impacts. Avoidance and minimization will be the primary methods of limiting negative impacts on fish and wildlife resources. Practices such as channel relocation, one sided construction, selective spoil placement and minimal clearing can be used both to protect existing sensitive areas and restore previously disturbed sensitive areas. Wildlife and water quality enhancement practices, such as plugging channels which drain wooded wetlands and creating berms along channels to prohibit wetland water from draining into the channel, will be included as part of the tax ditch plan when site conditions allow in order to mitigate temporary wildlife losses and to restore previously lost functions to these water dependent resources. [Principle and Guidelines for Planning, Constructing, and Maintaining Drainage Ditches in the State of Delaware, section C, June 1995]

5.9.5 Advisory Policy

5.9.5.1 The use of farmlands for non-agricultural purposes should be discouraged by the Farmers Home Administration and all other public financing programs. Instead, development should be directed to the numerous smaller communities which have adequate in-place public services and facilities, as well as adequate land area to accommodate new development.
