The U.S. Environmental Protection Agency (EPA) has not delegated authority to the state to administer the federal program; thus, 6iosolids generators must comply with requirements of both regulations, including repDrting and monitoring requirements. The required components of a Sludge (Biosolids) Management and Disposal Plan are described in the Wastewater Rules 1DAPA 58.01.16. A General Biosolids Land Application Plan for the City of Meridian was developed by Cl-12M HILL tin April of 1999 in accordance with 40 Code of Federal Regulations (Cl?R) Part 5IXi Regulation The Sludge (Bioso[ids) Management and Disposal Plan shall be developed in accordance with IDAPA 58.0'1.16 to include the following: • Land application maps that show the location of Relds, proximity to water supply wells, location of flood plains, residences, roadways and surface water • Copies of agreements from land owners • Laboratory analysis of soil from land application fields • Laboratory analysis of biosolids from the Municipal WWTP • Discussion of haw water quality and public health will be protected • Criteria for site selection of land application fields • Description of the application process • Procedwes utilized to prevent application which could result in a reduction of soil productivity or in the percolation of excess nutrients • Hydrologic characteristics of the site including existing quality and use of groundwater • Quality Assurance/Quality Control (QAQC~ Plan for soil sampling BASIS Of= DESIGN SC+4PE AND FEE DEVELOPMENT The following key assumptions were made in the compilation of this scope of work and the estimation of the level of effort: ow~r score of waxc 1. The planning work on this project will last 12 weeks from authorization to proceed and be completed in calendaz year , 2 T~ P~~g approach will be based on three interactive workshops and informal deliverables sketches, no more than 20 drawings, meeting minutes, and the likre as opposed to formal, comprehensive documentation such as TMs and extensive drawings. 3. The project will be executed in CH2M HILL's Boise design center. All workshops will be held in CH2M HILL's office or at the Municipal W WTP in Meridian, ID. 4. The Sludge (Biosolids} Management and Disposal Plan will be based on the federal, state, and local codes and standards in effect on the effective date of the authorization to proceed. Any changes in these codes may necessitate a change in scope. 5. The Sludge (Biosolids) Management and Disposal Plan will be pnapared as a single document. 6. The Owner will develop the actual permit application and required annual reports and PaY ~ Pmt Prang fees. 9. The drawings will follow CH2M HILL CAI;/CAD standazds. Microstation and ArcGIS will be used to develop the drawings. 8. The Owner will provide copies of all existing Biosolids Land Application Plans and arutual reports submitted to EPA on February 19~- of every yeaz for the past five years. These reports are considered true and accurate representation of the biosolids disposal and the Owner warrants the accuracy of these drawings.
