Jennifer,
It was a pleasure talking with you this afternoon regarding the City of Molalla’s NPDES permit requirements and the City’s efforts in addressing inflow and infiltration (I&I) issues within the City’s sanitary sewer system. I wanted to take a moment to summarize our key points of discussion:
· It is the DEQ’s understanding that the City is currently mapping the entire sanitary sewer system and is taking steps over the next year to address I&I issues. These steps include smoke testing, installation of flow meters (estimated for Feb/March 2015) for winter and summer flow monitoring, and video inspections of mainlines and laterals. The City hopes to have a defined plan for correcting I&II issues towards the end of 2015 and to actively engage in repairs and improvements starting in 2016. There is a potential that some repairs could be accomplished in 2016.
· We reviewed the principal schedules of your NPDES permit. In particular, we reviewed Table B13 (Reporting Requirements and Due Dates) on Pages 17 and 18 of the permit that summarizes all the reports (and due dates) associated with your permit. I pointed out that an annual I&I report is due to the DEQ by March 1 of each year.
· We also reviewed Condition 1 (Inflow Removal) of Schedule D (Special Conditions) of the NPDES Permit regarding the requirement to submit to DEQ for approval an updated Inflow Removal Program or Plan within 180 days of the effective date of the permit (June 1, 2014). If requested by the City, the DEQ may be able to provide examples of other plans or programs prepared by other sources to assist in the development of the City’s program.
· The DEQ recommended that the City become familiar with all schedules and conditions of the NPDES permit. We discussed that the NPDES permit regulates the discharge of treated wastewater and recycled water from the City’s sewage treatment plant. The NPDES permit does not authorize discharges to wetlands or other waters of the state relative to Section 404 of the Clean Water Act or Oregon Removal/Fill Law.
My general contact information is provided below for your use. Should you have any questions regarding your NPDES permit, please do not hesitate to contact me at the number listed below. I look forward to working with you in the future. Best wishes on your new position with the City of Molalla. Thanks. Mark
