Section 25208.17.
Cal. Health and Safety Code - HSC § 25208.17.
in effect(a)
Except as provided in subdivision (g), a person specified in subdivision (h) is exempt from filing the report required by Section 25208.7 if the surface impoundment has been closed, or will be closed before January 1, 1988, in accordance with Subchapter 15 (commencing with Section 2510) of Chapter 3 of Title 23 of the California Code of Regulations, and it has only been used for the discharge of economic poisons, as defined in Section 12753 of the Food and Agricultural Code, and if the person submits an application for exemption to
the regional board on or before February 1, 1987, pursuant to subdivision (b) and an initial hydrogeological site assessment report to the regional board on or before July 1, 1987. A qualified person shall be responsible for the preparation of the hydrogeological site assessment report and shall certify its completeness and accuracy.
(b)
A person seeking exemption from Section 25208.7 shall file an application for exemption with the regional board on or before February 1, 1987, together with an initial filing fee of three thousand dollars ($3,000). The application shall include the names of persons who own or operate each surface impoundment for which the exemption is sought and the location of each surface impoundment for which an exemption is sought.
(c)
Notwithstanding Section 25208.3, each person filing an application for exemption pursuant to subdivision (b) shall pay only
the application fee provided in subdivision (b) and any additional fees assessed by the state board to recover the actual costs incurred by the state board and regional boards to administer this section. The person is not liable for fees assessed pursuant to Section 25208.3, except that, if the person is required to comply with Section 25208.7 or 25208.6, the fees assessed under this section shall include the costs of the regional board and state board to administer those sections.
(d)
If a person fails to pay the initial filing fee by February 1, 1987, or fails to pay any subsequent additional assessment pursuant to subdivision (c), the person shall be liable for a penalty of not more than 100 percent of the fees due and unpaid, but in an amount sufficient to deter future noncompliance, as based upon that person’s past history of noncompliance and ability to pay, and upon additional expenses incurred by the regional board and state board as a
result of this noncompliance.
(e)
Notwithstanding Section 25208.3, after the regional board has made a determination pursuant to subdivision (g), a final payment or refund of fees specified in subdivision (c) shall be made so that the total fees paid by the person shall be sufficient to cover the actual costs of the state board and the regional board in administering this section.
(f)
The hydrogeological site assessment report shall contain, for each surface impoundment, all of the following information:
(1)
A description of the surface impoundment, including its physical characteristics, its age, the presence or absence of a liner, a description of the liner, the liner’s compatibility with the hazardous wastes discharged to the impoundment, and the design specifications of the impoundment.
(2)
A description of the volume and concentration of hazardous waste constituents placed in the surface impoundment, based on a representative chemical analysis of the specific hazardous waste type and accounting for variance in hazardous waste constituents over time.
(3)
An analysis of surface and groundwater on, under, and within one mile of the surface impoundment to provide a reliable indication of whether or not hazardous constituents or leachate is leaking or has been released from the surface impoundment.
(4)
A chemical characterization of soil-pore liquid in areas that are likely to be affected by hazardous constituents or leachate released from the surface impoundment, as compared to geologically similar areas near the surface impoundment that have not been affected by releases from the surface impoundment.
This characterization shall include both of the following:
(A)
A description of the composition of the vadose zone beneath the surface impoundment. This description shall include a chemical and hydrogeological characterization of both the consolidated and unconsolidated geologic materials underlying the surface impoundment, and an analysis for pollutants, including those constituents discharged into the surface impoundment. This description shall also include soil moisture readings from a representative number of points around the surface impoundment’s perimeter and at the maximum depth of the surface impoundment. If the regional board determines that the use of suction type soil sampling devices is infeasible due to climate, soil hydraulics, or soil texture, the regional board may authorize the use of alternative devices. The initial report shall contain all data in tabular form so that data, constituents, and concentrations are readily
discernible.
(B)
A determination of the chemical characteristics of the soil made by collecting a soil sample upgradient from the impoundment or from an area that has not been affected by seepage from the surface impoundment and that is in a hydrogeologic environment similar to the surface impoundment. The determinations shall be analyzed for the same pollutants analyzed pursuant to subparagraph (A).
(5)
A description of current groundwater and vadose zone monitoring being conducted at the surface impoundment for leak detection, including detailed plans and equipment specifications and a technical report that provides the rationale for the spatial distribution of groundwater and vadose zone monitoring points for the design of monitoring facilities, and for the selection of monitoring equipment. This description shall include:
(A)
A map showing the location of monitoring facilities with respect to each surface impoundment.
(B)
Drawings and design data showing construction details of groundwater monitoring facilities, including all of the following:
(i)
Casing and hole diameter.
(ii)
Casing materials.
(iii)
Depth of each monitoring well.
(iv)
Size and position of perforations.
(v)
Method for joining sections of casing.
(vi)
Nature and gradation of filter material.
(vii)
Depth and composition of annular
seals.
(viii)
Method and length of time of development.
(ix)
Method of drilling.
(C)
Specifications, drawings, and data for the location and installation of vadose zone monitoring equipment.
(D)
Discussion of sampling frequency and methods and analytical protocols used.
(E)
Justification of indicator parameters used.
(6)
Documentation demonstrating that the monitoring system and methods used at the facility can detect any seepage before the hazardous waste constituents enter the waters of the state. This documentation shall include, but is not limited to, substantiation of each of the following:
(A)
The monitoring facilities are located close enough to the surface impoundment to identify lateral and vertical migration of any constituents discharged to the impoundment.
(B)
The groundwater monitoring wells are not located within the influence of any adjacent pumping water wells that might impair their effectiveness.
(C)
The groundwater monitoring wells are screened only in the zone of groundwater to be monitored.
(D)
The casing material in the groundwater monitoring wells does not interfere with, or react to, the potential contaminants of major concern at the impoundment.
(E)
The casing diameter allows an adequate amount of water to be removed during sampling and allows full
development of each well.
(F)
The annular seal of each groundwater monitoring well prevents pollutants from migrating down the well.
(G)
The water samples are collected after at least five well volumes have been removed from the well and that the samples are collected, preserved, transported, handled, analyzed, and reported in accordance with guidelines for collection and analysis of groundwater samples that provide for preservation of unstable indicator parameters and prevent physical or chemical changes that could interfere with detection of indicator parameters. If the wells are low-yield wells, in that the wells are incapable of yielding three well volumes during a 24-hour period, the methods of water sample collection shall ensure that a representative sample is obtained from the well.
(H)
The hazardous waste
constituents selected for analysis are specific to the facility, taking into account the chemical composition of hazardous wastes previously placed in the surface impoundment.
(I)
The frequency of monitoring is sufficient to give timely warning of any leakage or release of hazardous constituents or leachate so that remedial action can be taken prior to any adverse changes in the quality of the groundwater.
(7)
A written statement from the qualified person preparing the report indicating whether any hazardous constituents or leachate has migrated into the vadose zone, water-bearing strata, or waters of the state in concentrations that pollute or threaten to pollute the waters of the state.
(8)
A written statement from the qualified person preparing the report indicating whether any migration of hazardous constituents
or leachate into the vadose zone, water-bearing strata, or waters of the state is likely or not likely to occur within five years, and any evidence supporting that statement.
(g)
The regional board shall complete a thorough analysis of each hydrogeological site assessment report submitted pursuant to subdivision (b) within one year after submittal. If the regional board determines that a hazardous waste constituent from the surface impoundment is polluting or threatening to pollute, as defined in subdivision (
l
) of Section 13050 of the Water Code, both of the following shall occur:
(1)
The regional board shall issue a cease and desist order or a cleanup and abatement order that prohibits any discharge into the surface impoundment and requires compliance with Section 25208.6.
(2)
The person shall file a report
pursuant to Section 25208.7 within nine months after the regional board makes the determination pursuant to subdivision (g). In making any determination under this subdivision, the regional board shall state the factual basis for the determinations.
(h)
For purposes of this section, “person” means only the following:
(1)
Pest control operators and businesses licensed pursuant to Section 11701 of the Food and Agricultural Code.
(2)
Local governmental vector control agencies who have entered into a cooperative agreement with the department pursuant to Section 116180.
