SSLAP – Lowell Snohomish River Road Agricultural Land ___________________________________________________________________________________ ______________________________________________________________________________________ 7 Biosolids will only be applied during the drier summer months when nutrient addition would provide a significant benefit. In the event of heavy seasonal rainstorms during this period, biosolids application will be curtailed to minimize the potential for ru noff. Biosolids will be applied in compliance with City of Everett’s noise ordinance, EMC Chapter 20.08. No operations will occur during times or under conditions that may adversely impact the public’s health, the environment or the safety of City or contractors’ work crews. • Contingency Plan The City of Everett Biosolids Program and the Contractor will handle any incidents, such as a spill, traffic, or work site accident. Incidents will be managed to minimize or eliminate hazards to operations personnel, the environment, and the public. The haul contractor will handle any incidents or problems in transporting biosolids to the site according to the City’s “Residuals Haul & Emergency Response Handbook.” The City’s Biosolids Program and the biosolids application contractor will manage incidents occurring after the delivery of biosolids. Compliance, Record Keeping, and Reports Regulatory compliance will be in accordance with federal regulations (40 CFR Part 503) State regulations (WAC 173-308) and any local jurisdiction with authority. The City Biosolids Program will keep records for 5 years on the quantity of biosolids applied and biosolids quality information including the metals concentrations, pathogen and vector attraction reduction requirements, and certification statements that state and federal requirements were met. Additionally, records are typically maintained for pre- and post-application monitoring data, application areas, acreage, application rates, and response to incidents.
