Okla. Admin. Code § 35:45-1-7

Current through Vol. 42, No. 6, December 2, 2024

Section 35:45-1-7 - Animal waste programs

(a) Compliance with antidegradation requirements and protection of beneficial uses.

(1) This area of jurisdiction includes the licensing or registering of CAFOs, LMFOs and poultry operations. These programs include land application of animal or poultry waste. Discharges of animal and poultry waste into waters of the State are statutorily prohibited. As a result, no discharge shall result from the operation of the facility. CAFOs and LMFOs may only discharge in the event of a 25 year/24 hour rainfall event and are required to construct the waste retention structures to contain the 25 year/24 hour rainfall event; except for new LMFO (swine), poultry and veal calves CAFOs, which are required to have waste management and storage facilities to contain all waste and runoff for 100 year/24 hour rainfall event. In addition, OAC 35:17-3-14(b)(3)(C) allows a facility which has been properly designed, constructed, and operated and is in danger of an imminent overflow due to chronic or catastrophic rainfall to discharge wastewaters to land application sites for filtering prior to discharging to surface or groundwaters of the state.

(2) Beneficial uses that could potentially be impaired by improper land application, leakage from animal waste lagoons, or breach of a lagoon could impact both ground water and surface water. Beneficial uses that could be affected include, but are not limited to:

(1) Fish and Wildlife Propagation may be impaired by lack of DO due to nutrient loading.

(2) Public and Private Water Supplies may be impaired by fecal coliform, algae growth, and nutrient loading.

(3) Recreation may be impaired by pathogens.

(4) Aesthetics may be impacted by nutrient loading. All of these impairments could be caused by unauthorized discharges to waters of the state.

(3) Violations of the "no discharge" standard for CAFOs, LMFOs, and poultry feeding operations result in enforcement actions. These actions integrate corrective and remedial activities that can include clean-up activities and restoration activities. Remediation requirements are determined on a case-by-case basis. The Department shall assess and review all approved remediation requirements to provide technical standards for future remediations.

(4) Education programs are also required for all poultry waste applicators, operators of poultry feeding operations, and employees of LMFOs. Employees responsible for permit compliance must be annually trained or informed of any information pertinent to the proper operation and maintenance of the facility and waste disposal.

(5) OAC 252:730 -13-5 provides that no new or increased point source discharges are allowed in water bodies and watersheds designated by the WQS as an ORW or Scenic River. Waters that have been classified as HQW and SWS according to OAC 252:730 -5-25 (c) (3) and (4) are prohibited from having any new point source discharge(s) of any pollutant or increased load or concentration of specified pollutants from existing point sources discharge(s), except as provided in the regulations. CAFOs are by definition point sources. In addition, all nonpoint sources shall implement best management practices in watersheds designated as ORW. However, if nonpoint sources are identified as significantly contributing to the degradation of a water body designated as an ORW, conservation plans shall be developed in subwatersheds. Finally, LMFOs established after August 1, 1998 applying for a new CAFO license or expansion after March 9, 1998 shall not be located within three (3) miles of any designated scenic river area or within one (1) mile of a water body designated as ORW.

(6) LMFO's that are located in nutrient-limited watersheds and or nutrient-vulnerable groundwaters shall meet current waste retention structure liner criteria according to Title 2, O.S. § 20-12(H)(3), and meet land application nutrient loading rate requirements per OAC 35:17-3-14(b)(4).

(7) Poultry feeding operations that are located in nutrient limited watersheds or nutrient vulnerable groundwaters as designated by OWRB shall meet soil and litter testing and litter application rate requirements per 2 O.S. § 10-9.7(E).

(b) Application of USAP - In the event ODAFF engages in surface water monitoring, USAP as adopted by OWRB will be consulted to determine if beneficial uses have been impaired. All animal waste programs require no discharges from facilities, therefore USAP is not applicable. Any discharge will be a violation of the license and subject to enforcement action and possible fines.

(c) Description of programs affecting water quality.

(1) The Agricultural Environmental Management Services (AEMS) Division of ODAFF is responsible for the review of applications for animal feeding operations that meet size and type requirements. The division also investigates complaints received by the Department regarding animal waste issues that could affect water quality.

(2) In December 2012, the EPA authorized ODAFF to perform NPDES permitting pursuant to the CWA. ODAFF reviews NOIs for authorizations pursuant to a general permit and reviews applications for individual permits. AgPDES activities include CAFOs, pesticides, silviculture, and storm water at agricultural facilities.

(3) The animal waste program, pesticide program, fertilizer program, and forestry management program can affect groundwater and surface water beneficial uses if facilities are not designed and operated properly. The application process is targeted at removing the possible threat of pollution to the waters of the State by not allowing any discharge to surface water, except in limited circumstances, by promoting recycle and beneficial reuse of wastewater, by not permitting any hydrologic connection between waste storage facility and groundwater, by preparing or reviewing animal waste management plans, nutrient management plans, or equivalent documents, emphasizing best management practices and conservation measures, and by routine inspections of regulated CAFOs, LMFOs, and poultry feeding operations.

(d) Technical information and procedures for implementation.

(1) All programs are involved in regulating the animal and poultry feeding operations to assure that facilities meet the minimum requirements. The programs evaluate facility location, watershed, soils, groundwater data, stream data, flood information, water samples, manure and litter samples, and other pertinent information. The application process evaluates the potential effects of the proposed operation on the waters of the State to insure both groundwater and surface water are not polluted. Potential impacts on beneficial uses designated in water quality standards will be further evaluated during the license application process to assist elimination of the threat to nutrient vulnerable groundwaters and nutrient impaired waters. Data collected from monitoring wells or soil test reports submitted by regulated operations will be evaluated to assess the potential impact on waters of the state. If noncompliance with operating requirements is found, technical assistance or appropriate enforcement measures will be used to bring regulated facilities into compliance with state laws and rules.

(2) The CAFO and poultry programs utilize a number of databases, software programs and models for implementation. These include: stream gage data from the U.S. Geological Survey; SQL databases for water quality data information; ArcInfo and ArcView GIS, MapWindows+MMP Tool software data analysis and mapping; precipitation and evaporation data from the National Weather Service and Oklahoma Climatological Survey; maps and hydrologic information from the U.S Geological Survey, Oklahoma Geological Survey, and Oklahoma Water Resources Board; USDA NRCS Soil Surveys and Technical Standards; OSU Oklahoma Cooperative Extension Service Fact Sheets; and other tools, software, and other guidance related to manure management planning developed by EPA, universities, and professional organizations, the MMP (Manure Management Plan) developed by Purdue University. Models may be obtained or developed to analyze information and data to assist in meeting WQS as necessary.

(e) Integration of WQSIP into water quality management activities - ODAFF rules for these programs require compliance with WQS pursuant to 2 O.S. § 20-10 (B) (4) (c) and 20-48(B)(4)(c) ensure that watersheds and groundwater are adequately protected pursuant to 20-10 (B)(4)(h) and 20-48(B)(4)(f). Future changes in Water Quality Standards may require additional rules and policies. Amendments will be made as necessitated by those changes.

(f) Compliance with mandated statewide water quality requirements - ODAFF will comply with other statewide water quality requirements by participating in the update of WQS, and in updates of the state's Continuing Planning Process document, Integrated Report, water quality management plan and other planning efforts. ODAFF will continue to participate in the Nonpoint Source Working Group and will cooperate with the Oklahoma Conservation Commission and others involved in NPS pollution prevention programs. ODAFF will participate in the TMDL process as resources permit, and will make use of the Beneficial Use Monitoring Program data compiled in cooperation with other state environmental agencies to modify its water quality program as necessary.

(g) Public and interagency participation.

(1) ODAFF interacts with other environmental agencies through the Water Quality Standards Implementation Advisory Committee. The agencies review and comment on each agency's plan and consult with each other as needed.

(2) Public participation requirements of the Oklahoma Administrative Procedures Act are followed in promulgating rules that integrate water quality standards into these program areas.

(h) Evaluation of effectiveness of agency activities.

(1) The effectiveness of these programs in the protection of designated beneficial uses for designated stream segments will be evaluated utilizing the following processes: review and integration of CAFO monitoring well sampling, soil analysis, stream gage data from the U.S. Geological Survey, U.S. Army Corps of Engineers, Oklahoma Conservation Commission, and Oklahoma Water Resources Board, and all other available data.

(2) The swine LMFO monitoring well sampling and laboratory analysis project began in 2000. All LMFOs with more than 1,000 swine animal units were required by Senate Bill 1175 of 1998 [Title 2 O.S. § 20-12(F)] to install and maintain a leak detection system or sufficient monitoring wells both upgradient and downgradient around the perimeter of each waste retention structure. ODAFF is required by Title 2 O.S. § 20-12(F) to sample and laboratory analyze the samples from the LMFO monitoring wells at least annually. The LMFO monitoring well samples are required in Title 35, Chapter 17, Subchapter 3 of the CAFO Permanent Rules [35:17-3-11.(6)(H)] to be sampled and laboratory analyzed for electrical conductivity, pH, ammonium-nitrogen, nitrate-nitrogen, total phosphorus and fecal coliform bacteria. The information and data collected under this program is published in a report annually by ODAFF.

(3) In the event groundwater problems are identified, ODAFF will take steps to identify the sources of the problems. If CAFOs or LMFOs are identified as the source, appropriate remediation activities will be implemented.
