North County Recycling Center and Sanitary Landfill Permit Revision Project Final Initial Study/Mitigated Negative Declaration · San Joaquin County | May 2025 49 REGULATORY SETTING Stormwater Pollution Prevention Plan The San Joaquin County facility operates under the Standard Industrial Classification (SIC) code 4953 for “landfills, land application sites, and open dumps”. Landfills are listed under Category #5 of Attachment A of the General Permit requiring permit coverage. Furthermore, operators of landfills are required to comply with Part 445 of 40 CFR Chapter I, Subchapter N, which specifies effluent limitation guidelines (ELGs) for specific categories of industrial storm water discharges. County staff is responsible for the monitoring and reporting requirements contained within the facility’s Stormwater Pollution Prevention Plan (SWPP), as required by Section X of the NPDES, General Industrial Storm Water Permit issued by the State of California SWRCB Water Quality Order 2014-0057-DWQ amended by Order 2015-0122-DWQ and Order 2018-0028-DWQ (General Permit). One of the core components of the SWPP is the identification and evaluation of pollutants that may affect the quality of storm water discharges and authorized non-storm water discharges from the facility. Furthermore, staff must also identify and describe best management practices (BMPs) to reduce or prevent pollutants in industrial storm water discharges. California Code of Regulations Title 27 § 20260 Class III landfills shall be located where site characteristics provide adequate separation between nonhazardous solid waste and waters of the state. Class III landfills are subject to State waste containment requirements and SWRCB requirements. New Class III and existing Class II-2 landfills shall be sited where soil characteristics, distance from waste to ground water, and other factors will ensure no impairment of beneficial uses of surface water or of ground water beneath or adjacent to the landfill. California Code of Regulations Title 27 § 20220 Non-hazardous solid waste are defined as “all putrescible and non-putrescible solid, semi-solid, and liquid wastes, including garbage, trash, refuse, paper, rubbish, ashes, industrial wastes, demolition and construction wastes, abandoned vehicles and parts, discarded home and industrial appliances, manure, vegetable or animal solid and semi-solid wastes and other discarded waste (whether of solid or semi-solid consistency); provided that such wastes do not contain wastes which must be managed as hazardous wastes, or wastes which contain soluble pollutants in concentrations which exceed applicable water quality objectives, or could cause degradation of waters of the state (i.e., designated waste).” Nonhazardous solid waste may be discharged at any classified landfill which is authorized to accept such waste, provided that (1) the co-disposal of nonhazardous solid waste with other waste shall not create conditions which could impair the facility’s containment features and shall not render designated waste hazardous, and (2) the facility shall ensure to the maximum extent feasible, that only those wastes that are approved for being discharged at that facility.
