Find the Failure
Separate a cracked shell from damaged fittings, blocked pipes, worn lids or a pump fault.
Match the Repair
Explain the proposed parts and access. Structural damage may make replacement more practical than a patch.
Confirm DEQ Review
Ask DEQ which repair or maintenance category applies. Field or treatment-unit replacement can follow a different permit path.
Protect Nearby Components
Locate utilities and the field before excavation. Preserve the approved replacement area.
Document the Work
Retain component details, approvals and relevant inspection records for future care or a sale.
