Article 9.6 - Land Treatment Units

California Health and Safety Code — §§ 25209-25209.7

Sections (18)

Added by Stats. 1987, Ch. 1374, Sec. 1.

The Legislature finds and declares as follows:

(a)Hazardous waste discharged into land treatment units may migrate beyond the treatment zone of the land treatment unit and thereby threaten the public health and the environment and pose a serious threat to the quality of the waters of this state.

(b)With the exception of land treatment units, all major forms of land disposal units are required by law to be equipped with liner and leachate collection and removal systems to ensure sufficient protection of the public health and

safety and the environment and to protect the quality of the waters of this state. It is in the public interest to extend these requirements to include land treatment units.

(c)It is the intent of the Legislature to establish a uniform and workable procedure for implementing requirements for liner and leachate collection and removal systems in all existing land treatment units, and replacements and lateral expansions of existing and new land treatment units, and to ensure that the vadose zone and groundwater beneath all land treatment units is adequately monitored to detect the presence of any contamination. Land treatment units in operation in this state must be made safe, or closed if necessary, to protect public health and safety and the environment, including the waters of the state.

§ 25209.1

Amended by Stats. 1990, Ch. 1686, Sec. 10.

For purposes of this article, the following definitions apply:

(a)“Discharge” means to place or dispose hazardous wastes in a land treatment unit.

(b)“Facility” has the meaning specified in Section 25117.1.

(c)“Hazardous constituent” has the meaning specified in regulations adopted by the department.

(d)“Hazardous waste” means a hazardous waste, as defined in Section 25117 and “non-RCRA

hazardous waste” has the same meaning as defined in Section 25117. 9.

(e)“Land treatment unit” means a facility or part of a facility at which hazardous waste is applied onto or incorporated into the soil surface so that hazardous constituents are degraded, transformed, or immobilized within the treatment zone.

above the highest anticipated elevation of the water table.

(h)“Vadose zone” means the unsaturated zone outside the treatment zone and between the land surface and the water table.

(i)“Waste management unit” has the meaning specified in the regulations adopted by the department.

§ 25209.2

Amended by Stats. 1990, Ch. 1686, Sec. 11.

(a)Except as provided in Section 25209.5, unless granted a variance pursuant to subdivision (b), or exempted pursuant to Section 25209.6, no person shall discharge hazardous waste into a new land treatment unit at a new or existing facility, any land treatment unit which replaces an existing land treatment unit, or any laterally expanded portion of an existing land treatment unit that has not been equipped with liners, a leachate collection and removal system, a groundwater monitoring system, and a vadose zone monitoring system which satisfy the requirements of Section 25209.5.

(b)The department may grant a variance from the requirements of subdivision (a) and Section 25209.3, concerning equipping the land treatment unit with liners and a leachate collection and removal system, if the owner or operator demonstrates to the department and the department finds all of the following:

(1)If the land treatment unit is an existing land treatment unit, no hazardous constituents have migrated from the treatment zone of the land treatment unit into the vadose zone or into the waters of the state. In making this demonstration the owner or operator shall take a sufficient number of core samples in, beneath, and surrounding the treatment zone of the land treatment unit to characterize the chemical constituents in the treatment zone, in the immediate area of the vadose zone surrounding the treatment zone, and in the area of the vadose zone beneath the treatment zone and shall submit groundwater monitoring data

sufficient in scope to demonstrate that there has been no migration of hazardous constituents into the vadose zone or into the waters of the state. The owner or operator, as an alternative to taking these core samples, may use the data obtained from any land treatment demonstration required by the department before issuing a hazardous waste facilities permit pursuant to Section 25200, if the data were obtained not more than two years prior to the application for the variance and is sufficient in scope to demonstrate that there has been no migration of hazardous constituents into the vadose zone or into the waters of the state.

(2)Notwithstanding the date that the land treatment unit commences operations, the design and operating practices will prevent the migration of hazardous constituents from the treatment zone of the land treatment unit into the vadose zone or into the waters of the state.

(3)Notwithstanding the date that the land treatment unit commences operations, the design and operating practices provide for rapid detection and removal or remediation of any hazardous constituents that migrate from the treatment zone of the land treatment unit into the vadose zone or into the waters of the state.

(c)(1) The department may renew a variance only in those cases where an owner or operator can demonstrate, and the department finds, both of the following:

(A) No hazardous constituents have migrated from the treatment zone of the land treatment unit into the vadose zone or into the waters of the state.

(B) Continuing the operation of the land treatment unit does not pose a significant potential of hazardous constituents migrating from the land treatment

unit into the vadose zone or into the waters of the state.

(2)In making the demonstration for the renewal of a variance pursuant to this subdivision, the owner or operator may use field tests, laboratory analyses, or, operating data.

(d)A variance, or a renewal of a variance, may be issued for a period not to exceed three years.

(e)Except for the exemption from vadose zone monitoring requirements specified in Section 25209.5, neither the requirements of this article nor the variance provisions of subdivision (b) shall relieve the owner or operator from responsibility to comply with all other existing laws and regulations pertinent to land treatment units.

§ 25209.3

Amended by Stats. 1988, Ch. 1632, Sec. 23.

(a)Every owner or operator of a land treatment unit subject to this article shall pay an annual fee to the department which shall be equivalent to 2 percent of the land disposal fee due under Section 25205.4. This fee shall be in addition to the annual hazardous waste facility fee and shall be due at the same time as the facility fee.

(b)The department may, by regulation, increase or decrease the amount of the fees specified in subdivision (a) if the department finds

that the amounts charged do not reflect the cost of providing services under this article.

§ 25209.10

Added by Stats. 2002, Ch. 597, Sec. 2. Effective January 1, 2003.

The Legislature finds and declares all of the following:

(a)The long-term economic and environmental sustainability of agriculture is critical to the future of the state, and it is in the interest of the state to enact policies that enhance that sustainability.

(b)High levels of salt and selenium are present in many soils in the state as a result of both natural occurrences and irrigation practices that concentrate their presence

in soils.

(c)The buildup of salt and selenium in agricultural soil is an unsustainable practice that degrades soil, harms an irreplaceable natural resource, reduces crop yields and farm income, and poses threats to wildlife.

(d)Salt and selenium buildup can degrade groundwater, especially in areas with perched groundwater aquifers.

(e)Off-farm drainage of irrigation water with high levels of salt and selenium degrades rivers and waterways, particularly the San Joaquin River and its tributaries. This environmental damage presents a clear and imminent danger that warrants immediate action to prevent or mitigate harm to public health and the environment.

(f)Discharge of agricultural drainage water to manmade drains and ponds has resulted in

environmental damage, including damage to wildlife. Proposals to discharge agricultural drainage to natural water bodies, including the San Francisco Bay, are extremely expensive and pose threats to the environmental quality of those water bodies.

(g)Water supplies for agricultural irrigation have been reduced significantly in recent years, necessitating increased efforts to use water more efficiently.

(h)Although salt can be collected and managed as a commercial farm commodity, California currently imports salt from other countries.

(i)Integrated on-farm drainage management is a sustainable system of managing salt-laden farm drainage water. Integrated on-farm drainage management is designed to eliminate the need for off-farm drainage of irrigation water, prevent the on-farm movement of irrigation and

drainage water to groundwater, restore and enhance the productive value of degraded farmland by removing salt and selenium from the soil, conserve water by reducing the demand for irrigation water, and create the potential to convert salt from a waste product and pollutant to a commercial farm commodity.

(j)Although integrated on-farm drainage management facilities are designed and operated expressly to prevent threats to groundwater and wildlife, these facilities currently may be classified as surface impoundments pursuant to the Toxic Pits Act of 1984, which discourages farmers from using them as an environmentally preferable means of managing agricultural drainage water.

(k)It is the policy of the state to conserve water and to minimize the environmental impacts of agricultural drainage. It is therefore in the interest of the state to encourage the voluntary

implementation of sustainable farming and irrigation practices, including, but not limited to, integrated on-farm drainage management, as a means of improving environmental protection, conserving water, restoring degraded soils, and enhancing the economic productivity of farms.

§ 25209.11

Amended by Stats. 2006, Ch. 309, Sec. 1. Effective January 1, 2007.

For purposes of this article, the following terms have the following meanings:

(a)“Agricultural drainage water” means surface drainage water or percolated irrigation water that is collected by subsurface drainage tiles placed beneath an agricultural field.

(b)“On-farm” means land within the boundaries of a property or geographically contiguous properties, owned or under the control of a single owner or operator or a publicly

organized land-based agency, that is used for the commercial production of agricultural commodities and that contains an integrated on-farm drainage management system and a solar evaporator.

(c)“Integrated on-farm drainage management system” means a facility for the on-farm management of agricultural drainage water that does all of the following:

(1)Reduces levels of salt and selenium in soil by the application of irrigation water to agricultural fields.

(2)Collects agricultural drainage water from irrigated fields and sequentially reuses that water to irrigate successive crops until the volume of residual agricultural drainage water is substantially decreased and its salt content significantly increased.

(3)Discharges the residual agricultural

drainage water to an on-farm solar evaporator for evaporation and appropriate salt management.

(4)Eliminates discharge of agricultural drainage water to evaporation ponds and outside the boundaries of the property or properties that produces the agricultural drainage water and that is served by the integrated on-farm drainage management system and the solar evaporator.

(d)“Publicly organized land-based agency” means a resource conservation district, as described in Division 9 (commencing with Section 9001) of the Public Resources Code, an irrigation district, as described in Division 11 (commencing with Section 20500) of the Water Code, any other district established pursuant to the Water Code whose operations may include managing agricultural irrigation or drainage, or a joint powers authority formed for the purpose of managing agricultural drainage or salt.

(e)“Regional board” means a California regional water quality control board.

(f)“Solar evaporator” means an on-farm area of land and its associated equipment that meets all of the following conditions:

(1)It is designed and operated to manage agricultural drainage water discharged from the integrated on-farm drainage management system.

(2)The area of the land that makes up the solar evaporator is equal to, or less than, 2 percent of the area of the land that is managed by the integrated on-farm drainage management system.

(3)Agricultural drainage water from the integrated on-farm drainage management system is discharged to the solar evaporator by timed sprinklers or other equipment that

allows the discharge rate to be set and adjusted as necessary to avoid standing water within the solar evaporator or, if a water catchment basin is part of the solar evaporator, within that portion of the solar evaporator that is outside the basin.

(4)The combination of the rate of discharge of agricultural drainage water to the solar evaporator and subsurface tile drainage under the solar evaporator provides adequate assurance that constituents in the agricultural drainage water will not migrate from the solar evaporator into the vadose zone or waters of the state in concentrations that pollute or threaten to pollute the waters of the state.

(g)“State board” means the State Water Resources Control Board.

(h)“Water catchment basin” means an area within the boundaries of a solar evaporator that is designated to

receive and hold any water that might otherwise be standing water within the solar evaporator. The entire area of a water catchment basin shall be permanently and continuously covered with netting, or otherwise designed, constructed, and operated to prevent access by avian wildlife to standing water within the basin.

Amended by Stats. 2006, Ch. 309, Sec. 2. Effective January 1, 2007.

The state board, in consultation, as necessary, with other appropriate state agencies, shall adopt or amend emergency regulations that establish minimum requirements for the design, construction, operation, and closure of a solar evaporator. The regulations shall include, but are not limited to, requirements to ensure all of the following:

(a)The operation of a solar evaporator does not result in a discharge of on-farm agricultural drainage water outside the boundaries of the area of land that

makes up the solar evaporator.

(b)(1) The solar evaporator is designed, constructed, and operated so that, under reasonably forseeable operating conditions, the discharge of agricultural water to the solar evaporator does not result in standing water or drift of salt spray, mist, or particles outside the boundaries of the solar evaporator to the extent that drift constitutes a nuisance condition.

(2)Notwithstanding paragraph (1), a solar evaporator may be designed, constructed, and operated to accommodate standing water, if it includes a water catchment basin.

(3)The board may specify those conditions under which a solar evaporator is required to include a water catchment basin to prevent standing water that would otherwise occur within the solar evaporator.

(c)Avian wildlife is adequately protected. In adopting regulations pursuant to this subdivision, the state board shall do the following:

(1)Consider and, to the extent feasible, incorporate best management practices recommended or adopted by the United States Fish and Wildlife Service.

(2)Establish guidelines for the authorized inspection of a solar evaporator by the regional board pursuant to Section 25209.15. The guidelines shall include technical advice developed in consultation with the Department of Fish and Game and the United States Fish and Wildlife Service that may be used by regional board personnel to identify observed conditions relating to the operation of a solar evaporator that indicate an unreasonable threat to avian wildlife.

(d)Constituents in agricultural drainage water discharged to the solar evaporator will not migrate from the solar evaporator into the vadose zone or the waters of the state in concentrations that pollute or threaten to pollute the waters of the state.

(e)Adequate groundwater monitoring and recordkeeping is performed to ensure compliance with this article.
