Letter included comments on point source and non-point source for total phosphorus. The facility that will receive wastewater associated with the proposed planned development must have adequate design capacity to treat the additional wastewater, including adequate phosphorus treatment capacity to remain within its assigned wasteload and concentration limits. Dominion Water and Sanitation District demonstrated that it has adequate capacity to treat the wastewater that would be generated by the proposed preliminary plan as part of the Sterling Ranch Planned Development. The planned development includes stormwater drain systems, detention ponds, and open space areas. Regulation 73.6(2) states the Authority “members shall implement nonpoint source control programs for those areas within their jurisdictions”. The project will need to comply with the Douglas County’s non-point source control programs including stormwater. Based on the above, the Authority takes no exception to the proposed planned development, provided it complies with Control Regulation 73 as defined in above comments.

Letter included comments on point source, including if septic tanks are needed, and non-point source for totaphosphorus. The Authority recently adopted the Commercial/Industrial Individual Sewage Disposal Systems Policy on November 20th, 2017. If the property requires a septic system which will generate 2,000 gallons per day (gpd) or more, the Authority requests the Applicant complies with the Commercial/Industrial Individual Sewage Disposal Systems Policy (this was attached to the response letter). Additionally, the Applicant would require submittal of a Colorado Discharge Permit System (CDPS) application if the Applicant needs a septic system greater than 2,000 gpd. Under Control Regulation 73, total phosphorus allocations are distributed among sources, including point sources (e.g., discharge permits). Therefore, if the Applicant requires a septic system greater than 2,000 gpd, a discharge permit is required and the point sourcedischarger shall show if phosphorus allocation are met. If total phosphorus allocation is in exceedance, the Division will not issue a discharge permit until phosphorus pounds are awarded from Reserve Pool, Trading Program, or by Temporary Transfers (Regulation 73.3(2)(a)). The Applicant stated “the current stormwater management plan will remain in effect to prevent all unlawful discharge into Plum Creek” on Lot 3. Regulation 73.6(2) states the Authority “members shall implement nonpoint source control programs for those areas within their jurisdictions”. The project will need to comply with the Douglas County’s non-point source control programs including stormwater. Based on the above, the Authority takes no exception to the proposed rezoning, provided it complies with Control Regulation 73 as defined in above comments
