J , that the plant on the proposed site will be managed t. minimize the potential adverse impacts on water quality, and must encourage the consolidatio; of wastewater treatment works whenever feasible. In making this determination, the Division requires each applicant for a site approval for a domestic wastewater treatment works to supply an engineering report describing the project ar showing the applicant 's capabilities to manage and operate the faility over the life of the project to determine the potential adverse impacts on water quality. The report shall be considered the culmination of the planning process and as a minimum shall address the following: Service area definition including existing population and population projections, flow/loading projections, and relationship to other water and wastewater treatment plants in the area. Proposed effluent limitations as developed in coordination with the Plrnning and Standard: Section of the Di%islon. (Allow minimum four weeks processing time. ) Analysis of existing facilities including performance of those facilities. Analysis of treatment alternatives considered. Flood plain and natural hazard analysis. Detailed description of selected alternatives including legal description of the site, treatment system description, design capacities, and cperatlonal staffing needs. Legal arrangements showing control of site for the project life. Institutional arrangements such as contract and/or covenant terms for all users which will be finalized to accomplished acceptable waste treatment. Management capabilities for controlling the wastewater throughout and treatment within the capacity limitations of the proposed treatment works, i.e. , user contracts, operating agreements, pretreatment requirements. Financial system which has been developed to provide for necessary capital and continued operation, maintenance, and replacement through the life of the project. This would include, for example, anticipated fee structure. Implementation plan and schedule including estimated construction time and estimated start-up date. 1'epending on the proposed project, some of the above items may not be applicable to address. in such cases, simply indicate on the application form the noo applicability of those. -4- WQCD-3 (Revised 8-83) 940 .n COLORADO DEPARTMENT HEALTH, Water Quality Control oivision Rationale -, Page 9.

Calculation of Water Quality Based Effluent Limitations A mass balance equation was used to determine the effluent concentrations that would not violate the allowable in-stream concentrations defined by the WQ standards (except in the case of pH, where the limits are set directly from stream standards or effluent regulations without using a mass balance approach). The mass balance equation is: M2 - M3Q3 - M1Q1, where: Q2 Ql - Upstream low flow (1E3 or 30E3) from Part III.8.2 Q2 - Average daily effluent flow (design capacity) 03 ' Combined downstream flow (Q1 + Q2) H1 " Upstream background pollutant concentration from III.B.1 M2 - Unknown; Maximum allowable effluent pollutant concentration calculated using mass balance equation M3 - Maximum downstream allowable pollutant concentration (stream standard) A summary of the mass balance calculations (if any) are shown and discussed in VII.C. 340710 \ as �sles'nrrcrrw R� J� ,�� IIfalli L-I \ttI l ' / —1 -- 4 Iwinallu\°\ ti wln lSUJ)'`..i 4 .is,pl(f`t < Q I)l\ —�}I\r• :iL.

Greeley, CO 80631 Dear Mr . Pickle : Enclosed is the application for site approval for expansion of the Greeley Water Pollution Control Facility. Your agency' s recommended approval is necessary prior to submitting the application to the Colorado Department of Health. A letter of map revision (LOMR) has already been requested from FEMA to redefine the floodway at the treatment plant site . The LOMR addresses the new Ash Avenue bridge over the Cache La Poudre River . Please return the site application to me at your earliest convenience . Also, please submit any written comments which the Weld County Health Department may have with regard to the City' s draft 201 Facility Plan update . On January 4 , 1994 , this document was sent to you with a cover letter explaining the City' s need to expand the existing sewage treatment facility. If you should have any questions or require additional information, please feel free to give me a call at 350-9365 . Thank you for your assistance. - l , Sincerely, J '� �C �Y - 4C cti sue.
