41805.5
. (a) Except as provided in subdivisions (b) and (c), the
operator of a solid waste disposal site shall submit to the district
on or before July 1, 1987, a solid waste air quality assessment test
report that contains all of the following:
(1) Test results to determine if there is any underground landfill
gas migration beyond the solid waste disposal site's perimeter.
(2) Analyses for specified air contaminants in the ambient air
adjacent to the solid waste disposal site to determine the effect of
the site on air quality.
(3) Chemical characterization test results to determine the
composition of gas streams immediately above the solid waste disposal
site, or immediately above the solid waste disposal site and within
the solid waste disposal site, as appropriate, as determined by the
district.
(4) Any other information that the district board requires, by
emergency regulation.
The solid waste air quality assessment test report shall be
prepared in accordance with the guidelines developed by the state
board pursuant to subdivision (d).
(b) The operator of an inactive solid waste disposal site shall
complete and submit the screening questionnaire, developed pursuant
to subdivision (e), to the district on or before November 1, 1986,
unless the operator is required to submit a report containing the
same information specified in subdivision (a) pursuant to a federal,
state, or district order, or unless exempted pursuant to subdivision
(c). The district shall evaluate the submitted screening
questionnaires in accordance with the guidelines developed pursuant
to subdivision (e) and shall determine whether the operator of the
site is required to submit all, or a portion of, the information
required to be reported in a solid waste air quality assessment test
report. The district shall notify the operator in writing on or
before January 1, 1987, of the information identified in subdivision
(a) to be submitted for the site. After receiving this notification,
the operator of the inactive solid waste disposal site shall submit a
solid waste air quality assessment test report containing the
required information on or before January 1, 1988, to the district.
(c) A district may exempt from subdivisions (a) and (b) a solid
waste disposal site or inactive solid waste disposal site that has
accepted or now contains only inert and nondecomposable solids. To
receive an exemption, the operator of the site shall submit, on or
before November 1, 1986, a copy of all permits, all waste discharge
requirements pertinent to the site, and any other data necessary for
the district to determine whether an exemption should be granted to
the site.
(d) On or before February 1, 1987, the state board, in
coordination with the districts, shall develop and publish test
guidelines for the solid waste air quality assessment report
specifying the air contaminants to be tested for and identifying
acceptable testing, analytical, and reporting methods to be employed
in completing the report.
(e) On or before October 1, 1986, the state board, in coordination
with the districts, shall develop and publish a screening
questionnaire for inactive solid waste disposal sites and guidelines
for evaluating the questionnaire by the districts pursuant to
subdivision (b). The screening questionnaire and guidelines shall
require an inactive solid waste disposal site to be evaluated based
on the nature and age of materials in the site, the quantity of
materials in the site, the size of the site, and other appropriate
factors. The guidelines for evaluating the screening questionnaire
shall require a district to weigh heavily the proximity of the site
to residences, schools, and other sensitive areas, and to pay
particular attention to potential adverse impacts on facilities such
as hospitals and schools, and on residential areas, within one mile
of the site's perimeter.
(f) A district may reevaluate the status of a solid waste disposal
site, including sites exempted pursuant to subdivision (c), and
require the operator to submit or revise a solid waste air quality
assessment test report after January 1, 1987. The district shall give
written notification to the operator of the solid waste disposal
site that a solid waste air quality assessment test report is to be
submitted, or that the existing report is to be revised, and the date
by which the report is to be submitted.
(g) A district shall evaluate any solid waste air quality
assessment test reports submitted pursuant to subdivisions (a), (b),
and (f), and determine if the report's testing, analytical, and
reporting methods comply with the guidelines developed pursuant to
subdivision (d). If the district determines that the solid waste air
quality assessment test report complies with the guidelines, it shall
evaluate the data. If the district determines, after evaluation of
the report and consultation with the state department and the
California Integrated Waste Management Board, that levels of one or
more specified air contaminants pose a health risk to human beings or
a threat to the environment, the district shall take appropriate
remedial action.
(h) If a district determines that a solid waste air quality
assessment test report does not comply with the guidelines developed
pursuant to subdivision (d), the district shall provide the operator
of the site with a written notice specifying the inadequacies of the
report and shall require the operator to correct the deficiencies and
resubmit the report by a date determined by the district.
(i) For the purpose of this section, the following definitions
apply:
(1) "Inactive solid waste disposal site" means a solid waste
disposal site that has not received any solid waste for disposal
after January 1, 1984.
(2) "Landfill gas" means any untreated, raw gas derived through a
natural process from the decomposition of organic waste deposited in
a solid waste disposal site or from the evolution of volatile species
in the waste.
(3) "Operator" means the person who operates or manages, or who
has operated or managed, the solid waste disposal site. If the
operator of the solid waste disposal site no longer exists, or is
unable, as determined by the district, to comply with the
requirements of this section, "operator" means any person who owns or
who has owned the solid waste disposal site.
(4) "Perimeter" means the outer boundary of the entire solid waste
disposal site property.
(5) "Solid waste disposal site" means a place, location, tract of
land, area, or premises in use, or which has been used, for the
landfill disposal of solid waste, as defined in Section 40191 of the
Public Resources Code, or hazardous waste, as defined in Section
40141 of the Public Resources Code, or both.
(6) "Specified air contaminants" means substances determined to be
air contaminants by the state board in coordination with the
districts. The state board and the districts shall consider
determining the following compounds to be air contaminants for
purposes of this paragraph: benzene, chloroethene, 1,2-dibromoethane,
1,2-dichloroethane benzyl chloride, chlorobenzene, dichlorobenzene,
1,1-dichloroethene, dichloromethane, formaldehyde, hydrogen sulfide,
tetrachloroethylene, tetrachloromethane, toluene,
1,1,1-trichloroethan e, trichloroethylene, trichloromethane, xylene,
and any other substance deemed appropriate by the state board or a
district.
