Operation & Maintenance (O&M)
Required to permit the reduction of soil treatment areas, vertical separation distances to limiting layers or reductions in horizontal separation distances by using higher level treatment systems are based on the criteria that these systems are functioning as designed. If these criteria are not met, failure or malfunction is likely, which could result in damage to public health and water quality.
EPCPH has developed a program of inspections, maintenance, recordkeeping and enforcement to ensure and document that higher level treatment systems are meeting the designed standards. Systems utilizing pressure distribution or an in tank treatment unit are required to provide a maintenance contract with a listed O & M Certified Inspector. Additionally, all newly installed systems require the submission of a maintenance inspection every 6 months for the first year followed by annual inspection thereafter.
