unnecessary treatment, costing significant money in excess fees by the <br /> Metropolitan Council Environmental Services (MCES) for that additional volume <br /> all being routed into the Pigs Eye Treatment Plant. <br /> Staff noted two kinds of inflow: that from illegal connections (e.g. sump pumps, <br /> downspouts, foundation drains) being channeled directly into sanitary sewer <br /> pipes; and inflow from groundwater seeping into sewer pipes due to cracks or <br /> leaky joints. Staff advised that this becomes a problem as the excess clear water <br /> uses sanitary sewer capacity needed for the treatment of the city's wastewater, <br /> often resulting in more back-ups and increased costs for treating that clear water. <br /> Staff further noted that the MCES required communities with excess UI to invest <br /> in local reduction remedies, including disconnecting sump pumps and foundation <br /> drains from the sanitary sewer system, and repairing leaky sanitary sewer pipes. <br /> Staff advised that the City of Roseville was one of 74 cities identified and <br /> required to pay an annual surcharge for that excess UL For the City as a whole, <br /> staff reviewed what was being done to reduce UI and this additional cost to City <br /> taxpayers and utility users through sanitary sewer lining, manhole inspections, <br /> and sump pump inspections. <br /> With the current Sewer Use and Regulations Ordinance (Chapter 802) originally <br /> adopted in 1969, with only minor revisions since then, staff noted the need for a <br /> general update of the entire chapter, as well as incorporating the sump pump <br /> inspection portion (Section 802.06.h) specific to construction requirements; and <br /> additional language in Section 802.08 prohibiting certain discharges. <br /> Chair Stenlund addressed the lack of specifics regarding pollution prevention <br /> requirements omitted in Section 802.06 during the construction process, with staff <br /> advising that any and all ground water management was part of the application, <br /> permitting, and review process to ensure environmental structures during <br /> construction work. <br /> As noted by Member Cihacek, staff confirmed that other parts of City Code <br /> addressed that (e.g. permit requirements for anything utility related) with erosion <br /> control addressed as part of that construction and under separate sections of City <br /> Code. <br /> Member Stenlund noted the need to address how and where soils being excavated <br /> are stored and managed (e.g. no "garbage" allowed in the hole, smells, and <br /> mottles of how to perform the work). <br /> Staff advised that the proposed language revisions incorporated into the new draft <br /> for Chapter 802 had been researched from the ordinance examples from the <br /> Village of St. Anthony and the City of Golden Valley. <br /> Page 3 of 14 <br />
