MWMC FACILmES PLAN The upgrade qualified all nine buildings to meet the current building code requirements for seismic loading. Public Health Risk from Catastrophic Release of Chlorine and Sulfur Dioxide Structural deficiencies at the plant could pose health risks if a seismic event resulted in structural damage to facilities and building collapse (risk to plant workers), or chemical release (risk to plant workers and the public). However, the recommended seismic upgrades have been completed and, therefore, potential public health risks from seismic activity near the WPCF are low. Additional information on the RMP for chlorine and sulfur dioxide is presented above. Biosolids Transport Biosolids are transported from the WPCF via pipeline to the BMF at a separate site. There, they are put into a sludge lagoon and subsequently processed (dewatered). The dewatered cake is transported via trucks to cooperative farms for land application. These are Class B biosolids, highly regulated, and not fit for land application on crops for human consumption. Alternatively, biosolids will be pumped in liquid form to the Biocycle Farm for liquid land application, or dewatered cake will be transported via truck for land application. Because biosolids are transported offsite, via pumping or by truck, and spread for land application, there is potential for a spill. However, a cleanup and response protocol for biosolids spills is in place, and the potential for public health hazards resulting from a biosolids spills is low. Public Health Risks from Biosolids Transport As noted above, biosolids are transported to onsite application areas through an enclosed biosolids distribution system, and dewatered cake is transported via trucks to cooperative farms for land application. If additional neighboring land is required for disposal, biosolids will be transported off site by truck. MWMC has developed a spill response plan that details actions to take in the event of a biosolids spill. The plan includes over-the-road spill response and clean-up proceduress. 2.2.5 Energy Management and Consumption During development of the 1997 Master Plan (CH2M HILL, 1997), a condition assessment of the WPCF was performed. This evaluation confirmed that the facility's energy consumption is extremely low in comparison to other similar treatment facilities. The plant operating staff has been very cognizant of energy consumption in the operation of the facility, and has been aggressive in both implementing improvements to reduce energy consumption and in obtaining grant funding to implement those improvements. Staff also have further managed continuous improvement of energy consumption through development and implementation of a Environmental Management System. The WPCF is ISO 14001 certified and includes an ongoing objective to reduce energy consumption. Numerous work programs have been implemented that include targets and measures to manage its continuous improvement strategy. 5 MWMC's biosolids spill response and cleanup procedures are adapted from the Biosolids Hauler Spill Response Procedure~CWEA Manual of Good Practice for Agricultural Land Application of Biosolids, 1998. 2-16 MWMC_2.0_REV23.DOC
