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 an, 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 Planning and Standard: Section of the Division. (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 operational 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 wil be finalized to accomplished acceptable waste treatment. Management capabilities for controlling the wastewater throughout and treatment within th( 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. Depending 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 non applicability of those. -4- WQCD-3 (Revised 8-83) S31338 Attachment to Site Application The City of Thornton would like to run a pilot program, using sewage effluent from the Town of Pierce to irrigate approximately 18 acres of farmland. The basic concept is to use the available treated effluent from the Pierce facility in conjunction with ditch water to irrigate the farmland. The proposed project will not interfere with or change the treatment process currently in place at the Pierce facility. The effluent currently runs into one of three rapid infiltration ponds built under NPDES Permit Number CO-0041211 . The City of Thornton is proposing to divert the water from the infiltration ponds to an irrigation lateral . When the lagoon is full approximately 1 . 16 cfs will be available for irrigation. When the level of the lagoon drops about 2 feet to the bottom of the outlet pipes in the maximum amount of water available will be about .6 cfs. The total amount of water available for this project is 14 acre-feet when the lagoon is full and can be used at a maximum rate of 1 . 16 cfs to 0.6 cfs depending on the level of the lagoon. The usable storage in the lagoon could be used in about 8 days at maximum rates. It will , however, take just about one month to fill the lagoon again at the maximum daily design capacity of the treatment facility. Although the amount of water available for irrigation will be limited in this operation the City of Thornton will be using the project to show that treated sewage effluent can be used to irrigate farmland.

The plant consists of the following major elements: an aeration pond with three surface aerators, a chlorinator, and three infiltration ponds. Four groundwater monitoring wells (one up-gradient and three down-gradient) are utilized to collect groundwater samples to monitor the effluent quality. The Town of Pierce and the City of Thornton have entered into an agreement to mix the waste water effluent with irrigation water from the Collins Lateral . The mixed water would be used to irrigate approximately 18 acres of farm land adjacent to the plant (Figure 1) . The mixed water would be used periodically during the months of April through October. When mixed water is not being used, the effluent would be discharged through the infiltration ponds in accordance with the existing permit. DESCRIPTION OF PROPOSED OPERATION Effluent would be discharged at rates ranging from 0 to 0.6 cubic feet per second (cfs) , depending on crop need and/or nutrient load. Flow of irrigation water in the lateral would range from .6 to .7 cfs, resulting in a maximum ratio of lateral water to effluent of 1 to 1 . The maximum usable storage of the lagoon is 14 acre-feet. The discharge from the lagoon would vary from 0 to 0.6 cfs. At the maximum rate of flow it would take approximately 12 days to drain the storage capacity of the lagoon. It would take approximately 30 days to refill the lagoon at the design capacity of influent flow. Consequently, the 30-day average flow would be 1 891338 rg`i f� 0. 1521 million gallons per day (MGD) . This value is less than the existing permitted capacity of 0. 1788 MGD. SITE CHARACTERISTICS The site is characterized by relatively flat terrain, which slopes to the south at approximately 25 feet per mile (< 1%) . The principal surface water feature in the area is Spring Creek, which drains the proposed area to be irrigated. Soil in the area is the Dacono Clay Loam. The thickness of the soil is approximately 2.3 feet. The soils are derived from the underlying sand, and silty clay. Figure 2 is a hydrogeologic cross-section drawn through four wells drilled just east of the facility. The cross-section indicates that the soils are underlain by 3 to 5 feet of sandy, silty clay. Underlying the clay is 25 to 27 feet of very gravelly sand. Underlying the sand is bedrock. The bedrock is the Laramie Formation, which is composed of shale, claystone and siltstone. The City of Thornton has been monitoring the water levels in the wells Ishown on the cross-section. Depth to water measurements are made twice a month during the irrigation season, and once a month during the non-irrigation Iseason. IThe seasonal maximum and minimum water levels are shown on Figure 2. Water levels are highest near the end of the irrigation season and lowest just Iafter the start of the irrigation season. Water level measurements in the monitoring wells around the infiltration pond show the same relationship. 1 Figure 3 is a contour map of March, 1987 water level measurements in 1 select wells in the area of the facility. The contours indicate that groundwater is flowing to the south-southeast at a gradient of 25 feet per 1 2 • 891338 ■ i mile. A long-term pc ping test was conducted in an i, rigation well just east of the facility (Figure 1) during September of 1987. The analyses of the test idata indicated a hydraulic conductivity on the order of 500 to 750 feet per ' day (ft/day) . Groundwater modeling conducted by the City of Thornton indicates a value of effective porosity of 0.20. Applying Darcy's Law: R = Ki/Pe Where: R is the rate of groundwater flow in feet per day K is hydraulic conductivity in feet per day i is the hydraulic gradient in ft/ft, and Pe is the effective porosity (dimensionless) ' yields a range of flow rates of 13 to 19 feet per day (4,700 to 6,900 feet per year) . 1 WATER QUALITY Three types of water will be involved in the proposed program. The ' three types are as follows: 1) Collins Lateral , i2) Waste Water Effluent, and 3) Groundwater Samples of these three types of water have been collected and analyzed for select chemical parameters and bacteria. The results of the analyses for general water quality parameters are summarized on Table 1 , and complete results are presented in Appendix A-1 . The analyses indicate that Collins Lateral water has the best overall water quality, and the groundwater has the ' lowest quality. Collins Lateral water is characterized by low nitrates and chlorides, and moderate to high sulfate, total dissolved solids and coliform bacteria. Monitoring Well Number 4 is the up-gradient well . The analyses for this well 3 891338 are most representative of ambient groundwater quality. The analyses for Well Number 4 indicate that the groundwater is characterized by relatively low chlorides and high nitrates, sulfates, TDS and coliform bacteria (Sulfates, TDS and coliform bacteria exceed drinking water standards) . Analyses for trace metals in the Collins water and the effluent indicate the concentrations are either below detection limits or well below standards for drinking water, human health and agriculture (Table 2) . MONITORING The City of Thornton proposes to install a monitoring well at the location shown on Figure 1 . Two samples would be collected during December, 1989 and March, 1990, to act as background water quality indicators. During the irrigation season, groundwater samples would be obtained monthly from the proposed monitoring well and the existing monitoring wells. Analytical parameters for the monthly samples would be the same as those specified in the existing permit. The background water quality samples would be analyzed for the same parameters plus the drinking water metals. A soil sample was collected from the area to be irrigated. The sample was analyzed for physical properties and geochemical characteristics. The results of the analyses are presented on Table 3 . We propose to collect soil samples annually from the irrigated fields and analyze them for the parameters indicated on Table 3. These parameters were selected to monitor the uptake of metals and nutrients in the soil .

Weld County Health Dept . 1516 Hospital Road Greeley , CO 80631 RE : November 21st Hearing on the Town of Pierce ' s Site Application . Dear Wes , I understand that the Planning Commission continued action on the Site Application until December 5 , 1989 . The continuance will allow Weld County Staff and the applicant to discuss issues raised at the hearing . I would like to address some of these issues if I may . If and when the Site Application is approved the City of Thornton will enter into an "Operations Agreement" that will address the overall operation of the sewage lagoon with the Town of Pierce . Issues addressed will include but not be limited to : 1 ) The proposed operation of surface discharge of effluent will occur during the irrigation season and will return to infiltration bed discharge during the off -season and at other times when surface discharge is not feasible or permitted . 2 ) Operations will be monitored keeping the processes within the lagoon , functioning as designed thus keeping the effluent in compliance with the NEDES permit . Ground water shall also be monitored . Reports sh,.111 be routinely submitted to the Town of Pierce and Weld County Health Department . 891338 3 ) Sewage effluent will be co-mingled with surface irrigation waters at' a ratio of no less then one to one during the irrigation season . (May through October) No surface discharge shall occur unless surface irrigation water is available for co-mingling . 4 ) Compensation for leasing the sewage effluent . I will attend the Weld County Planning Commission Hearing on Tuesday , December 5th , and be available for • any questions or discussion regarding the Site Application . Thank You .

The Division recommends conditional approval based upon the following. A. That the facility rigidly follow a non-degradation policy regarding the groundwater at the application site. The Weld County Health Department strongly endorses the concept of not degrading the groundwater quality beyond the existing levels at the site. B. That the facility managers conduct consistent monitoring of the effluent quality, irrigation water quality, and the field crop uptake. The effluent application rates shall be adjusted accordingly to insure that the water percolating to the groundwater table will not degrade that water quality below the existing levels at this date. This adjustment would include termination of the application of effluent in the event that the groundwater quality at the site is deteriorating. • WP309/cs L[L±&y 17 1 . Weld Co.
