City of Everett, Public Works Department, Water Pollution Control Facility BIOSOLIDS SAMPLING & ANALYSIS PLAN 10 b. Biosolids Nutrient Sampling Nutrient sampling of biosolids for agronomic rate determination is most representative if the samples are collected from dewatered biosolids. City of Everett biosolids that are land applied must meet Class B and Table 3 limits. To preserve the lifetime of the City owned application site, biosolids with pollutant concentrations that would require recording accumulative loading to the site will be landfilled in a Subtitle D facility. All the samples sent to the lab for analysis will be collected according to the protocol in Section 3B. 5. Data Analysis Review Recordkeeping and reporting will be per WAC 173-308-290 for Recordkeeping; and WAC 173-308-295 for Annual Reports. All required records and analytical data will be kept for a minimum of five years. Additionally, the Biosolids Program has developed a database that tracks pollutant levels of biosolids in the aeration cells. Soil sampling data, Chain-of-Custody forms, and Field Sampling Records are kept in a site-specific land application file created for each application site. Compost quality data, kept in a chronological file by year, is submitted to Ecology prior to beneficial use offsite and with the Annual Report required under WAC 173-308-295. 6.
