DRAFT [TENTATIVE] WASTE DISCHARGE REQUIREMENTS ORDER R5-2023-OOXX 67 FORWARD, INC. FORWARD LANDFILL SAN JOAQUIN COUNTY STANDARD PROVISIONS & REPORTING REQUIREMENTS 2. Leachate and landfill gas condensate collected from a waste management unit shall be discharged to the unit from which it came, or discharged to an appropriate waste management unit in accordance with Title 27 and in a manner consistent with the waste classification of the liquid [Title 27, § 20200(d) and § 20340(g)]. 3. The discharge of leachate or landfill gas condensate is restricted to those portions of a waste management unit that has a composite liner system and LCRS meeting the Federal Subtitle D requirements [40 C.F.R. § 258.28]. 4. Leachate and condensate returned to a composite-lined landfill unit (when approved by this Order) shall be discharged and managed such that it does not cause instability of the waste, does not cause leachate seeps, does not generate additional landfill gas that is not extracted from the landfill by an active landfill gas extraction system, does not cause contaminants to enter surface water runoff, and does not cause leachate volumes to exceed the maximum capacity of the LCRS. 5. Any discharge of waste outside the portion of the landfill that was already covered with waste as of the landfill unit's respective Federal Deadline constitutes a "lateral expansion" and requires the installation of an approved composite liner system and LCRS [40 C.F.R. § 258.40(b)]. 6. Wastes shall be discharged only into waste management units specifically designed for their containment and/or treatment, as described in this Order. 7. The discharge shall remain within the designated disposal area at all times. 8. The discharge of waste shall not cause a nuisance condition [Wat. Code, § 13050(m)]. E. Standard Facility Specifications 1. All waste management units shall be designed, constructed, and operated to ensure that wastes, including leachate, will be a minimum of 5 feet above the highest anticipated elevation of underlying groundwater [Title 27, § 20240(c)], including the capillary fringe. 2. Surface and subsurface drainage from outside of a waste management unit shall be diverted from the unit [Title 27, § 20365(e)].
