Bill Summary:(1) SB 995 requires the Department of Water Resources (DWR), on or before January 1, 2019, to update the well standards for water wells, monitoring wells, and cathodic protection wells. The bill also requires DWR to establish an advisory panel to identify critical gaps in existing knowledge about the best practices, and to conduct any necessary research and submit a report, by January 1, 2022, to the State Water Resources Control Board (SWRCB) outlining any recommendations. Upon the receipt of recommendations, SWRCB must revise the model water well, cathodic protection well, and monitoring well drilling and abandonment ordinance adopted pursuant to Section 13801. Fiscal Impact: According to DWR, the well standards update required in this bill will cost approximately $1.7 million (General Fund). However, DWR notes that there are significant information gaps that must be filled to develop the best possible standards. As SB 995 (Pavley) Page 1 of ? such, the "true" cost of an appropriate update would be approximately $6.6 million over a five-year period to perform the task below. Background: On average, California's groundwater provides approximately 30-46 percent of the state's total water supply and serves as a critical buffer against droughts. During dry years, groundwater may be used to meet nearly all of a community's water needs. Some communities do not have access to surface water sources and depend completely on groundwater sources to meet their needs. California has four categories of water wells: (1) "water wells" (sometimes called production wells are built to extract water for human consumption, irrigation, or other purposes; (2) "monitoring wells" are built to collect water samples and monitor groundwater levels; (3) "cathodic protection wells" are built to protect metallic objects buried in the ground from corrosion; and (4) "geothermal heat exchange wells" (GHEWs) are built to transfer heat to and from the soil as part of a heating, ventilation and cooling systems (HVAC). In the past, the Department of Water Resources (DWR) has been responsible for developing standards for the construction, maintenance, and destruction of all types of water wells. These standards are necessary in order to protect groundwater from contamination. If improperly built, maintained or destroyed, water wells can act as a conduit for contaminants. New advances in drilling materials and techniques have emerged since the adoption of well standards (outlined in Bulletin 74-90). Proposed Law: This bill: (2)Requires the DWR, on or before January 1, 2019, to update the well standards contained in Bulletin 74-81 and Bulletin 74-90 based on existing knowledge of water wells, monitoring wells, and cathodic protection wells. (3)Requires DWR to establish an advisory panel to identify SB 995 (Pavley) Page 2 of ? critical gaps in existing knowledge about the best practices for well construction, alteration, maintenance, and destruction for the types of wells. If the advisory panel identifies knowledge gaps that need further research, DWR must conduct scientific research to address those needs. (4)On or before January 1, 2022, the advisory panel must make recommendations for improvements in well regulations that DWR must submit to the SWRCB. (5)Upon the receipt of recommendations, the SWRCB must revise the model water well, cathodic protection well, and monitoring well drilling and abandonment ordinance. Related Legislation: AB 2334 (Cortese, Chapter 581, Statutes of 1996) required DWR to develop and submit to the SWRCB a report containing recommended standards for GHEWs. Staff Notes: Staff notes that this bill excludes GHEWs DWR issued a Draft of Standards for GHEWs in 1999, with the ultimate goal of creating one bulletin (Bulletin 74-99) to cover all four types of wells (water wells, monitoring wells, cathodic protection wells and geothermal heat exchange wells). However, due to delays, Bulletin 74-99 was never formalized and the GHEW standards remain as a Draft. Recently, DWR has been working through a review of the Draft 1999 GHEW standards and is nearly finished. Because the GHEWs standards are almost finalized, this bill does not include GHEWs. -- END --
