OAR 340-093-0150: Construction Certification

Except as provided in OAR 340-093-0070(4): (1) The department may require, upon completion of major or critical construction at a disposal site or waste tire storage site, that the permittee submit to the department a final project report signed by the project engineer or manager as appropriate. The report must certify that construction has been completed in accordance with the approved plans including any approved amendments thereto. (2) If any major or critical construction has been scheduled in the plans for phase development subsequent to the initial operation, the department may require that the permittee submit additional certification for each phase when construction of that phase is completed. (3) Solid waste may not be disposed of in any new waste management unit (such as a landfill cell) of a land disposal site unless/until the permittee has received prior written approval from the department of the required engineering design, construction, Construction Quality Assurance, operations, and monitoring plans. Only after the department has accepted a construction certification report prepared by an independent party, certifying to the department that the unit was constructed in accordance with the approved plans, may waste be placed in the unit. If the department does not respond to a certified construction certification report within 30 days of its receipt, the permittee may proceed to use the unit for disposal of the intended solid waste.
