Environmental Standard Procedure <br /> Pate h <br /> 3.3.4.6. T6 (30% Sodium Hydroxide Storage Tank) — 540 gal double contained <br /> HDPE tank placed above grade on an epoxy coated double contained <br /> concrete slab that provides tertiary containment. 30% Sodium Hydroxide <br /> solution from T6 is automatically pumped to T3, T4 or T5 via metering <br /> pump to neutralize any transferred process waste solution. <br /> 3.3.4.7. T7 (36% Sulfuric acid Storage Tanis) -- 540 gal double contained HDPE <br /> tank placed above grade on an epoxy coated double contained concrete <br /> slab that provides tertiary containment. 30% Sodium Hydroxide solution <br /> from T6 is automatically pumped to T3, T4 or T5 via metering pump to <br /> neutralize any transferred process waste solution. <br /> 3.3.4.8. T8 (Non-RCRA Hazardous Waste Storage Tank) — 500 gal double <br /> contained HDPE tank placed above grade on an epoxy coated double <br /> contained concrete slab that provides tertiary containment. Hazardous <br /> waste is pumped into the tank via overhead schedule 80 piping. The waste <br /> is disposed offsite via hazardous waste manifest. <br /> 3.3.4.9. T9 (Nora-RCRA Hazardous caste Storage Tank) — 500 gal double <br /> contained HDPE tank placed above grade on an epoxy coated double <br /> contained concrete slab that provides tertiary containment. Hazardous <br /> waste is pumped into the tank via overhead schedule 84 piping. The waste <br /> is disposed offsite via hazardous waste manifest. <br /> 3.3.4.10. T10 (NonµRCRA Hazardous Waste Storage Tank) -- 500 gal double <br /> contained HDPE tank placed above grade on an epoxy coated double <br /> contained concrete slab that provides tertiary containment. Hazardous <br /> waste is pumped into the tank via overhead schedule 80 piping. The waste <br /> is disposed offsite via hazardous waste manifest. <br /> 3.3.4.11. V1 (Discharge Valve) — neutralized industrial process waste water from T5 <br /> is discharged via V1 in the open position into the City of Lodi sewer system <br /> in accordance with the City of Lodi Wastewater Discharge Permit# 579. <br /> V1 is closed if there is any risk of accidental or non-compliant off-site <br /> discharge. <br /> 3.3.4.12. V2 (Retreatrrment Valve) -- industrial process waste water from T5 is <br /> discharged back to T1 via V2 in the open position if re-treatment is <br /> necessary. V2 is closed unless re-treatment is necessary. <br /> 3.3.4.13. V3 (T1 Output Valve) — V3 is open during normal operation and closed <br /> after hours to prevent the output fine from losing "prime." <br /> 3.3.4.14. V4 (Secondary Containment Valve) — V4 is in the closed position during <br /> normal conditions. In the event of an accidental discharge or rain water <br /> collection within the epoxy coated concrete slab and berm secondary <br /> containment area, V4 in the closed position will ensure that collected <br /> material can be investigated prior to introduction into T1. <br /> 3.4. Inspections and Discharge Monitoring Procedure <br /> 3.4.1. Discharge Monitoring Procedure <br /> 3.4.4.1. Step 1 Identify the waste and estimate the volume to be discharged. <br />
