INITIAL PUBLIC NOTICE: Critical Facility Standby Generator Implementation Program Calaveras County, California | HMGP 4431-034-007R

The U.S. Department of Homeland Security’s Federal Emergency Management Agency (FEMA) intends to provide federal financial assistance under the Hazard Mitigation Grant Program (HMGP) to the Calaveras County Water District (CCWD) in Calaveras County, California to provide emergency standby power. The proposed project will install generators at 11 sites throughout the CCWD for key facilities that are currently without emergency standby power. The project sites include six lift stations, four wells and tanks, and one location that is the main radio transmission communication hub for the CCWD’s radio and supervisory control and data acquisition (SCADA) communications systems. The proposed action would mitigate impacts from multiple natural disasters (including flood, wildfire, wind, atmospheric river storms, and landslides), as well as Public Safety Planned Shutdown (PSPS) events. Pursuant to Executive Order 11988 (Floodplain Management) and Executive Order 11990 (Wetlands Management) and FEMA’s implementing regulations at Title 44 of the Code of Federal Regulations Part 9, FEMA hereby provides interested parties with a notice of its intent to carry out an action affecting a floodplain and wetlands.

The purpose of the proposed action is to provide emergency standby power. The stationary standby generators would be placed in secure locations, on concrete slabs, and fenced. At each site, the generators would be placed on a 4-inch or 6-inch-thick concrete pad located above existing grade. The depth of disturbance would be 2 feet or less, and no more than 20 feet in length. The generators are approximately 6 feet wide and 18 feet long. All fuel tanks would be installed above ground per manufacturer's specifications. Fuel tanks would be double walled with built-in containment. Spill kits would be located at each site.

The Wallace Well 3 project area is in the 100-year floodplain as depicted on the FEMA Flood Insurance Rate Map (FIRM) panel number 06009C0350E, effective 12/17/2010. The FIRM shows that the project area lies within Special Flood Hazard Area (SFHA) Zone A. SFHA zones are defined as the areas that will be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year. The 1-percent annual chance flood is also referred to as the base flood or 100-year flood.

The U.S. Fish and Wildlife Service National Wetlands Inventory map shows the project is located outside of wetlands and not likely to result in any potential direct impacts that will adversely affect wetlands.

Additional information about FEMA’s proposed action, including maps showing the potential impacts on floodplains and wetlands, may be obtained by writing the FEMA Region IX Environmental Officer at FEMA, 1111 Broadway, Suite 1200, Oakland, California 94607, or fema- rix-ehp-documents@fema.dhs.gov. All requests should be received within 15 days after publication of this notice.
