(a) All applications shall contain the following information: - (i) Identification of the type of water supply system proposed to serve the subdivision and identification of the entity or entities responsible for the design, construction, operation and maintenance of the proposed facility;
- (ii) The estimated average and maximum number of gallons per day for the subdivision water supply system;
- (iii) Documentation that the proposed water supply system will be compatible with and not adversely affected by the sewage system proposed for the subdivision or any other sources of pollution within a reasonable distance;
- (iv) List of all surface and groundwater rights which will be used or which may be affected, including state engineer application and permit numbers and description of expected effects;
- (v) Plans for the mitigation of water right conflicts resulting from the use of water within the proposed subdivision; and
- (v) The information required by W.S. 18-5-306(a) (xi).
(b) In addition to the information required in part (a) of this section, applications proposing to connect to an existing water supply system shall contain the following: - (i) Documentation concerning the potability of the proposed water supply for the subdivision as evidenced by historic water quality analytical data and current compliance status;
- (ii) Certification by the owner of the water distribution and treatment facilities that the system can and will provide adequate service to the proposed subdivision. This certification should address the willingness and a commitment of the owner to provide service, as well as the hydraulic capacity of the distribution system and the ability of the treatment facilities to provide potable water to the proposed subdivision;
- (A) The certification shall clearly identify the point of connection if the connection is not within the boundaries of the proposed subdivision.
- (B) It is the responsibility of the owner to consider the capacity and ability of the system to provide water service to the proposed subdivision in accordance with existing laws, regulations and permit requirements.
- (iii) The information required by Section 6, Chapter 12, Wyoming Water Quality Rules and Regulations shall be provided by a registered professional engineer. If the necessary information is not already available, the owner of the water system has the discretion to require the subdivider to provide the required information.
- (vi) The party responsible for operation and maintenance of the subdivision distribution system will provide for certified operators pursuant to Chapter 5, Wyoming Water Quality Rules and Regulations.
(c) In addition to the information required in part (a) of this section, applications proposing to develop a new centralized water supply system shall contain the following: - (i) A demonstration that the water supply system is sufficient in terms of quality, quantity and dependability and will be available to ensure an adequate water supply system for the type of subdivision proposed. The report shall include a narrative summary of:
- (A) Where the water supply system source is derived from groundwater, the geologic setting of the water supply system source and the area of influence such as nearby communities, sources of pollution, surface water bodies and aquifers described by a Wyoming registered professional geologist;
- (B) A written report demonstrating that the proposed source is sufficient in terms of quality, quantity and dependability for the type of subdivision proposed;
- (C) Source of the water to be used including proposed and existing surface and groundwater facilities and their locations;
- (D) The proposed disposal of water not consumed, including water obtained under permits, storm drainage, dewatering, sewage and other wastewater sources;
- (E) A delineation of primary sources of water, secondary sources and occasional or seasonal sources;
- (F) Graphic location of all water supply sources including wells, raw water intakes, treatment facilities, treated water storage facilities and ponds;
- (G) Documentation of all data sources on the occurrence and availability of surface and groundwater;
- (H) Historic stream flows and well levels;
- (J) Flood damage and flood protection; and
- (K) Impact of and protection from supply shortages.
- (ii) The information required by Chapter 12, Section 6 of Wyoming Water Quality Rules and Regulations.
- (iii) Confirmation that the owner of the subdivision distribution system will provide for certified operators pursuant to Chapter 5, Wyoming Water Quality Rules and Regulations.
- (iv) Water quality data that is representative of the proposed drinking water source must be provided for the metals, inorganic constituents, and microbial constituents with Maximum Contaminant Levels (MCLs) established pursuant to the federal Safe Drinking Water Act.
(d) In addition to the information required in part (a) of this section, applications proposing to use on-lot wells or surface water that will serve fewer than 25 people shall contain information describing the potential availability and quality of groundwater or surface water proposed within the subdivision. This information may consist of new data, existing data on other working wells in the area, or other data, including drilling logs, from a test well drilled within the proposed subdivision indicating soil types, depth, quantity and quality of water produced in the test well. - (i) For subdivisions proposing to use on-lot wells or surface water that will serve individual residences or fewer than 25 people, water quality data that is representative of the proposed drinking water source must be provided for the following analytes:
- (A) Total Dissolved Solids (TDS)
- (B) Nitrate + Nitrite as N
- (Q) Additional constituents as may be deemed necessary by the department.
- (ii) Documentation of activities, within a distance of one quarter (¼) mile of the subdivision's external boundaries, that may have potential to adversely effect the quality of the drinking water supply.
