WASTE DISCHARGE REQU*MENTS ORDER NO. R5-2004-0021 -26- CITY OF MANTECA, CITY OF LATHROP AND DUTRA FARMS WASTEWATER QUALITY CONTROL FACILITY SAN JOAQUIN COUNTY requirements under Title 22 criteria. The Regional Board finds, on balance, that these requirements are necessary to protect the beneficial uses of the San Joaquin River, including water contact recreation and irrigation uses. STORMWATER 59. Federal Regulations for stormwater discharges are contained in 40 CFR Parts 122, 123, and 124. The regulations require specific categories of facilities,which discharge stormwater associated with industrial activity(stormwater) to obtain NPDES permits and implement Best Available Technology Economically Achievable (BAT) and Best Conventional Pollutant Control Technology(BCT) to reduce or eliminate industrial stormwater pollution. 60. Regulated stormwater discharges include those from facilities used in storage, treatment, recycling, and reclamation of municipal or domestic sewage, including land dedicated to the disposal of sewage sludge that are located within the confines of the facility,with a design flow of 1 mgd or more, or required to have an approved pretreatment program under 40 CFR Part 403. Not included are farmlands, domestic gardens, or lands used for sludge management where sludge is beneficially reused and which are not physically located in the confines of the facility, or areas that are in compliance with Clean Water Act Section 405. 61. The State Board adopted Order 97-03-DWQ (General NPDES Permit No. CAS000001) specifying waste discharge requirements for discharges of stormwater associated with industrial activities, excluding construction activities, and requiring submittal of a Notice of Intent by industries to be covered under the Order. This Order further specified that if an individual Order is adopted for stormwater runoff from a facility,then the General Permit would no longer apply. Since all stormwater that falls on the treatment plant site is collected and pumped to the secondary-treated wastewater storage ponds of the plant, a Storrnwater Pollution Prevention Plan has not been made a requirement of this Order. RECLAMATION 62. Wastewater is currently used to irrigate 210 acres of agricultural land owned by the City of Manteca, and 150 acres of leased land owned by Dutra Farms. DHS has established statewide reclamation criteria in Title 22, California Code of Regulations, Section 60301, et seq. (hereafter Title 22) for the use of reclaimed water, and has developed guidelines for specific uses. This Order requires compliance with applicable Title 22 requirements. PRETREATMENT 63. Clean Water Act Section 307(b) and Federal Regulations at 40 CFR Part 403 require publicly, owned treatment works to develop an acceptable industrial pretreatment program. A pretreatment program is required to prevent the introduction of pollutants that will interfere with treatment plant operations or sludge disposal and prevent pass through of pollutants that exceed water quality objectives, standards, or permit limitations.
