What is The Sewer Use and Wastewater Control Ordinance?  Sets requirements for sanitary sewer users  Regulates the discharge of pollutants into the collection system  Enables the Water Authority to achieve compliance with U.S. EPA National Pollutant Discharge Elimination System (NPDES) and Southside Water Reclamation Plant (SWRP) effluent and sludge limits.

Limitations on Sludge Disposal Injury to Workers Options and/or from Hazardous Greater Fumes Expense Corrosion of Collection System and/or Treatment Plant Explosions Interference with Wastewater Pass-Through of Treatment Facility Toxics into Surface Waters

Why a new Ordinance?  A requirement of the new U.S. EPA National Pollutant Discharge Elimination System (NPDES) permit for SWRP

Ordinance Process  EPA MODEL PRETREATMENT ORDINANCE Office of Wastewater Management/Permits Division http://www.epa.gov/npdes/pubs/pretreatment_model_suo.pdf  Reviewed 40 CFR 403 Pretreatment regulations  Reviewed other Publicly Owned Treatment Works (POTWs) Pretreatment Ordinances

Ordinance Process  Draft Ordinance  Public Participation  Meetings  Ordinance, ERP, FOG Policy posted online  Incorporation of Comments  Submitted to EPA by October 1, 2013  EPA has comments or gives certificate of approvability  Ordinance posted publicly for one month  Water Authority Board approves and incorporates new ordinance

Ordinance Requirement: Fats, Oil and Grease (FOG)  Capacity, Management Operations, and Maintenance (CMOM) Plan with an emphasis on FOG policy  FOG policy is a re-evaluation of the existing Ordinance  Grease Removal System (GRS) Requirements  Maintenance  Inspections  Record Keeping  Best Management Practices (BMPs)  Enforcement Response Plan 7

Changes From The Previous Ordinance: Fats, Oil and Grease  Maintenance:  Minimum cleaning every 6 months  25% rule 8

Changes From The Previous Ordinance: Fats, Oil and Grease  Clarifies who needs grease removal systems  food service establishments,  wastewater discharge permit holders,  automotive shops,  vehicle fueling stations,  any other fats, oil, and grease dischargers  Clarification of ordinance violations  Must use a pumper that is not in violation 9

FOG Policy: Pumper Requirements  Complete Evacuation  All chambers must be pumped  No decanting or discharging of wastewater back into trap  Manifests  Must be provided  Date, time, volume, condition  Prohibitions  Discharging of unprocessed GRS waste at SWRP  Blending 10

Ordinance Requirement: Septage Haulers  Discharges:  Must be in compliance with Section 3-2-1 Prohibited Pollutants  TPH: 100 mg/l  FOG: 100 mg/l (animal/vegetable)  pH: 5.0 – 12.0  No remediation water

Ordinance Requirement: All Discharges  Administrative Assessments: power to assess at least $1,000.00 per violation per day  Is spelled out in Rate Ordinance passed 6/19/13  http://www.abcwua.org/Legislation___Ordinances.aspx
