Stockton Delta Resorts, LLC 2 - 26 July 2017 Tower Park Marina and Tower Park Village upcoming meeting of the Central Valley Regional Water Board. Effective upon rescission of Order 94-078, the discharge shall be regulated pursuant to the General Order, EXISTING FACILITY AND DISCHARGE DESCRIPTION The Tower Park Marina and Village WWTP is owned and operated by Stockton Delta Resorts, LLC (hereafter "Discharger") and is located at 14900 West Highway 12 in San Joaquin County, as shown on Attachment A, which is attached hereto and is made part of this NOA by reference. The facility occupies assessor's parcel numbers 055-260-03, 055-260-04, 055-030-01, 055-030-09, and 055-030-13. The marina is located approximately six miles from the nearest municipal system at White Slough, which is owned and operated by the City of Lodi. The fees needed to connect to the City of Lodi's treatment facility are currently too costly for the Tower Park facility. Therefore, wastewater is collected and treated on-site. The site plan is shown on Attachment B and a wastewater flow schematic is shown on Attachment C, which are attached hereto and made part of this NOA by reference. The wastewater treatment system collects wastewater generated from 200 manufactured homes in the Tower Park Village, the marina, and nearby campgrounds. Wastewater from recreational vehicles (RVs) is discharged to the treatment system, provided the RVs do not use formaldehyde- based products in their holding tanks, in accordance with Sections B.2.b and B.3.d of the General Order. If an RV has used these types of products, they are required to empty their tanks prior to connecting to the Discharger's treatment system. In addition, these requirements are described in the reservation and site map literature given to all RV guests. The wastewater system consists of a WWTP, an aeration pond with a secondary unlined evaporation pond, two lift stations (LS1 and LS2), and a leachfield. Wastewater is pumped to the WWTP and/or the unlined aeration pond for disposal. Influent flows to the WWTP vary from 10,000 to 60,000 gallons per day (gpd). The service area at Tower Park is fully built out and not allowing any new water or sewer connections. Between the two lift stations is a manually control value that can direct wastewater to the WWTP or the aeration pond as needed to maintain freeboard in the aeration pond or to allow the leachfield additional drying time. Generally, wastewater collected during dry months (March through October) is directed to the WWTP, which consists of two activated sludge package treatment plants that provide a combined treatment capacity of 80,000 gpd. Pretreatment consists of primary clarification through grinder pumps to break up large objects and uses gravity to settle out solids. Floating debris that passes through the grinder is hand skimmed daily. The WWTP consists of two clarifiers, an aerobic reactor, stabilization tank. sand filter, and chlorination chamber. Sludge and solids are re-circulated back to the package plants. Chlorination is the final treatment stage prior to discharging to the leachfield. The leachfield consist of approximately 3.3 acres and is divided into two sections. Effluent is applied to one area for a two week cycle and then to the other area for two weeks to allow for sufficient infiltration of the wastewater and to avoid ponding and other nuisances. Grasses grown on the leachfields are frequently mowed and occasionally disked. During the winter or wet months, wastewater is generally discharged to the unlined aeration pond where it evaporates and percolates. During periods of heavy rainfall, the adjacent unlined evaporation pond is used to maintain two feet of freeboard in the aeration pond. Both ponds are located in the southern portion of the facility, approximately 110 to 150 feet west of Little Potato Slough, which may not meet the required setbacks included in the General Order (see Section B.1.1 below). Pond dimensions are shown below.
