2.1. FACILITY / SITE DESCRIPTION

[A.R.S. § 49-243(K)(8)]

The La Posa Long Term Visitor Area (LTVA) is an 11,400-acre campground and land-management area located approximately 2 miles south of Quartzite, AZ. The LTVA is managed by the Bureau of Land Management (BLM) through the Yuma Field Office. The wastewater evaporation lagoon will collect wastewater from a new dump station for recreational vehicles. Wastewater from the RV dump station will be discharged to the wastewater lagoons for treatment and evaporation to the atmosphere. The lagoons will replace the current dump station, septic tank, and leach field wastewater system, which will be closed once the new facilities are completed. The Wastewater Lagoon is part of an overall infrastructure upgrade to the LTVA which also includes a new well and water distribution system.

The proposed lagoon treatment system will have an annual average capacity of 36,100 gallons per day (gpd) and will consist of a manual bar screen, two septic tanks in series, a lagoon with a partially aerated cell, and secondary cell. Inflow rates will vary throughout the season with an estimated annual average influent flow rate of 36,100 gpd. The majority of inflow (60, 500 gpd) occurs between September and April that peaks to 200,000 gpd in January. The primary lagoon and secondary lagoon cells both have 5 MG (662,000 cubic feet [cf]) of storage, for a maximum total storage volume of 10 MG.

From the dump station, the wastewater will flow by gravity to the manual screen in a concrete box below grade.

The manual screen will be approximately 10 feet from the nearest dump station inlet pipe, minimizing the pipe length to be flushed if clogged. The bar screen will have 0.75-inch bars spaced with 1.25-inches of clear space and perpendicular to the floor to remove rags and large solids. The screen will be raked manually. A 7-feet by 5-feet concrete drain pad next to the screen box will allow the screenings to drain liquid back into the screen box and dry before offsite disposal.

After the manual screen, there will be two 5,000-gallon septic tanks in series. The tanks will have internal baffles to collect fats, oils, and grease at the surface and solids at the bottom. The wastewater will be allowed to emulsify to prevent clogs in the conveyance lines. The tanks will be spaced approximately 10 feet apart. From the septic tanks, the wastewater will flow by gravity to the aerated lagoon cell. The aerated lagoon cell will have a volume of approximately 5 million gallons (MG).

Two positive displacement blowers (one duty, one standby) will supply air to the lagoon to provide mixing and to facilitate aerobic treatment of the waste. The blowers will be 10 horsepower (hp) each and will be fully redundant. The air will be diffused by fine-bubble diffusers to allow efficient air transfer in the aerated lagoon.

The diffusers will be made of PTFE for dissolved solids resistance. The diffuser modules will rest on the pond floor by cloth-lined concrete ballast weights.

The aerated lagoon cell effluent will overflow to the secondary lagoon cell through an intercell control structure.

The secondary lagoon cell will have a volume of approximately 5 MG. The wastewater will be impounded in the secondary cell as it undergoes anaerobic treatment, solids settlement, and eventually evaporates to the atmosphere.

No startup plan is required for this facility. Permittee shall collect 1 sample of the RV dump and one sample from the discharge to the pond and test for the constituents on Table 6: . No industrial waste or other non-residential waste is allowed into the treatment system.

The site includes the following permitted discharging facilities:

If the closure plan achieves clean-closure immediately, ADEQ shall issue a letter of approval to the permittee.

If the closure plan contains a schedule for bringing the facility to a clean-closure configuration at a future date, ADEQ may incorporate any part of the schedule as an amendment to this permit.

2.9.2. Closure Completion

Upon completion of closure activities, the permittee shall give written notice to the Groundwater Protection Value Stream indicating that the approved closure plan has been implemented fully and providing supporting documentation to demonstrate that clean-closure has been achieved (soil sample results, verification sampling results, groundwater data, as applicable). If clean-closure has been achieved, ADEQ shall issue a letter of approval to the permittee at that time. If any of the following conditions apply, the permittee shall follow the terms of post-closure stated in this permit:

1. Clean-closure cannot be achieved at the time of closure notification or within one year thereafter under a diligent schedule of closure actions;

2. Further action is necessary to keep the facility in compliance with the AWQS at the applicable POC or, for any pollutant for which the AWQS was exceeded at the time this permit was issued, further action is necessary to prevent the facility from further degrading the aquifer at the applicable POC with respect to that pollutant;

3. Remedial, mitigative or corrective actions or controls are necessary to comply with A.R.S. § 49- 201(30) and Title 49, Chapter 2, Article 3;
