The document was distributed by the City of Lathrop Public Works Department and is identified by State Clearinghouse No. 2001122108. This letter provides comments on the DEIR and identifies issues that may require further discussion. Project Description The project would expand and upgrade the existing City of Lathrop Water Recycling Plant No. 1 by 3.0 million gallons per day of tertiary treatment capacity in four stages, each increase providing an additional 0.75 million gallons per day (mgd) of capacity. The improvements would be separate from the existing treatment plant that would continue to accept industrial wastewater from the Crossroads Industrial Development. The project would also construct a new collection system for proposed residential developments and a recycled water storage and distribution system. Initially the treatment and disposal system would apply all wastewater to land but the City also desires the ability to discharge treated wastewater to surface water in the future. The DEIR only address the wastewater application to land. The issue of surface water discharge has been discussed numerous times with the City, and in a 16 December 1999 letter, the Regional Board provided the City a list of items to be addressed in a Report of Waste Discharge (RWD) in 16 December 1999 correspondence. That letter is attached to this document. The DEIR describes the wastewater system in general but is not specific enough to allow the Regional Board to evaluate some statements or to determine if adequate land application areas exist. Further description of those items will be required for the RWD that is required prior to preparation of tentative Waste Discharge Requirements (WDRs).
