Additionally, this bill: 1)Requires DWR to submit these standards to the State Water Resources Control Board (SWRCB). 2)Requires SWRCB, upon receiving the updated well standards from DWR, to revise the model ordinance which includes water well, monitoring well, and cathodic protection well drilling and abandonment standards. FISCAL EFFECT: 1)According to DWR, an update of the well standards based on existing knowledge will cost approximately $1.7 million (General Fund). However, DWR notes there are significant information gaps that must be filled to develop the best possible standards, regardless of statutory requirements. As such, DWR estimates the cost of an appropriate update to be approximately $6.6 million over a five-year period. 2)SWRCB costs to update the model ordinance are absorbable. COMMENTS: 1)Purpose. DWR originally published standards for wells in 1968 and the most recent update was published in 1991. According to the author, the current standards are woefully out of date and do not cover the wide range of new materials and techniques developed by the well drilling industry. This bill requires the well standards to be updated. SB 995 Page 3 2)Background. DWR has the responsibility for developing standards for wells for the protection of water quality. California has four categories of water wells: a) "water wells" (sometimes called production wells) are built to extract water for human consumption, irrigation, or other purposes; b) "monitoring wells" are built to collect water samples and monitor groundwater levels; c) "cathodic protection wells" are built to protect metallic objects buried in the ground from corrosion; and d) "geothermal heat exchange wells" (GHEWs) are built to transfer heat to and from the soil as part of heating, ventilation and cooling systems (HVAC). DWR is currently in the final stages of updating GHEWs standards, so all but GHEWs are included in this bill. 3)DWR Bulletins. Statewide standards for water wells were first formally published in 1968 as DWR Bulletin 74, Water Well Standards: State of California. Standards for cathodic protection wells followed in 1973 as Bulletin 74-1, Cathodic Protection Well Standards: State of California. A revised edition of Bulletin 74 was published in 1981 as Bulletin 74-81, Water Well Standards: State of California. In 1991. Bulletin 74-90 was published as a supplement to Bulletin 74-81. Bulletin 74-90 was developed to respond to DWR's responsibilities under the Water Code and to keep pace with technical advances during the ten-year period following the publishing of Bulletin 74-81.
