(a) For the purposes of this article, the following
definitions shall apply:
(1) "Public drinking water well" means a wellhead that provides
drinking water to a public water system, as that term is defined in
Section 116275, that is regulated by the State Water Resources
Control Board and that is subject to Section 116455.
(2) "MTBE" means methyl tertiary-butyl ether.
(3) "GIS mapping system" means a geographic information system
that collects, stores, retrieves, analyzes, and displays
environmental geographic data in a data base that is accessible to
(4) "Motor vehicle fuel" includes gasoline, natural gasoline,
blends of gasoline and alcohol or gasoline and oxygenates, and any
inflammable liquid, by whatever name the liquid may be known or sold,
that is used or usable for propelling motor vehicles operated by the
explosion type engine. It does not include kerosine, liquefied
petroleum gas, or natural gas, in liquid or gaseous form.
(5) "Oxygenated motor vehicle fuel" is motor vehicle fuel, as
defined in paragraph (4), that meets the federal definition for
"Oxygenated fuel" in Section 7545(m) of Title 42 of the United States
(6) "Oxygenate" means an organic compound containing oxygen that
has been approved by the United States Environmental Protection
Agency as a gasoline additive to meet the requirements for an
"oxygenated fuel" pursuant to Section 7545 of Title 42 of the United
(b) The State Water Resources Control Board shall upgrade the data
base created by Section 25296.35. This upgrade shall include the
establishment of a statewide GIS mapping system as described in this
section only upon an appropriation by the Legislature for this
(c) (1) For purposes of subdivision (b), the board shall create a
GIS Mapping and Data Management Advisory Committee. The committee
shall give the board advice on location standards, protocols,
metadata, and the appropriate data to expand the data base to create
a cost-effective GIS mapping system that will provide the appropriate
information to allow agencies to better protect public drinking
water wells and, if feasible, nearby aquifers that are reasonably
expected to be used as drinking water, from contamination by motor
vehicle fuel from underground storage tanks and intrastate and
interstate pipelines that are regulated by the State Fire Marshal
pursuant to the California Pipeline Safety Act of 1981, Chapter 5.5
(commencing with Section 51010.5) of Part 1 of Division 1 of Title 5
of the Government Code.
(2) The advisory committee shall include, at a minimum, members
from appropriate state and local agencies, affected industry and
business, the water agencies that provide drinking water in Santa
Monica, the water agencies that provide drinking water in the Santa
Clara Valley, nonprofit environmental groups dedicated to the
conservation and preservation of natural resources, and underground
storage tank owners.
(d) (1) The board shall create two pilot projects, the Santa
Monica Groundwater Pilot Project and the Santa Clara Valley
Groundwater Pilot Project, which shall terminate on July 1, 1999.
(2) The board shall create the pilot projects with the advice of
the advisory committee so as to expedite and prioritize the upgrading
of the data base for those regions of the state where groundwater
provides, or would be called on in an emergency to provide, a
significant portion of the region's drinking water.
(3) The board shall use the pilot projects to define and assess
the parameters of the data base, identify data needs, develop
opportunities to electronically link data bases and electronic
submission of information, offer access to the public via the
Internet, streamline existing processes, and work out the details for
data management and a GIS mapping system as described in this
(4) The pilot projects shall study appropriate notification to
public water systems and response times.
(e) To upgrade the data base as required by this section, the
board, in consultation with the advisory committee, shall do all of
(1) Coordinate with the Department of Water Resources and the
State Department of Public Health to obtain the location of existing
drinking water wells and appropriate water resource and quality data
to meet the requirements of this article.
(2) Coordinate with local agencies authorized to implement this
chapter to obtain the location of all underground storage tanks that
store motor vehicle fuel that are within 1,000 feet of a public
drinking water well.
(3) Coordinate with local agencies authorized to implement this
chapter to add the location of all known releases of motor vehicle
fuel from underground storage tanks that are within 1,000 feet of a
drinking water well.
(4) Coordinate with the State Fire Marshal to add the location and
leak history of all pipelines or segments of pipelines that
transport motor vehicle fuel and that are regulated by the State Fire
Marshal pursuant to Chapter 5.5 (commencing with Section 51010) of
Part 1 of Division 1 of Title 5 of the Government Code that are
within 1,000 feet of an existing public drinking water well.
(f) The board may expend up to four hundred thousand dollars
($400,000) from the Underground Storage Tank Cleanup Fund for the
purposes set forth in Section 25299.36 to fund the GIS mapping system
projects referred to in this section.
