10.01.010 - Purpose and Policies.¶
The purpose of this Chapter is to establish uniform standards in order to control the location, design, and maintenance of hazardous waste facilities and to protect the health, quality of life, and the environment of the residents of the City.
(a) The City prioritizes hazardous waste management strategies as follows: source reduction (top priority), on-site recycling, off-site recycling, on-site treatment, off-site treatment, and disposal (last priority).
(b) The City will place public participation as a top priority throughout the process of siting hazardous waste facility projects.
(c) The City will cooperate fully with other local, State and Federal agencies to efficiently regulate the management of hazardous materials and hazardous waste.
(d) Transportation of hazardous waste will be minimized, and regulated where possible, to avoid environmentally sensitive areas and populated, congested, and dangerous routes, especially within the City.
(e) The regulations governing the discharge of hazardous waste into sanitation systems will be strictly enforced.
(f) The City recognizes that household hazardous wastes are a problem, and will work with San Bernardino County to ensure that household hazardous wastes are properly managed and not deposited in County landfills. The City of Twentynine Palms General Plan, when such Plan is prepared, shall address types and quantities of household hazardous waste generated in the City, options and strategies for managing these wastes, and a program for educating the residents of the City as to identification and proper management of household hazardous waste.

(90-88 § D)
10.01.050 - Standards and Locational Criteria.¶
All specified hazardous waste facility projects in the City must comply with the following provisions:
(a) Proximity to Populations. For a residual repository, as that term is defined in the Health & Safety Code, the distance from the active portion of the facility to one or more residences must be a minimum of two thousand feet (2,000′).
Treatment and storage facilities, as those terms are defined in the Health & Safety Code, should comply with zoning setback requirements for business park facilities, unless a greater distance is justified pursuant to a risk assessment.
(b) Proximity to Immobile Populations. For all types of facilities, a risk assessment must be performed which details the maximum credible accident from the facility operations and its impact on all immobile populations in the City. The extent of the study must appropriately address the quantity and types of wastes that could be received at the facility. It must also include consideration of the design features and planned operational practices at the facility. Additionally, the study must provide an estimate of the distance over which the affects of a spill or emergency situation would carry, a variety of options for reducing the risks, and procedures for dealing with such spills or emergency situations.
(c) Capability of Emergency Services. All facilities shall locate in areas where fire departments are able to immediately respond to hazardous materials accidents, where mutual aid and immediate aid agreements are well established, and where demonstrated emergency response times are the same or better than those recommended by the National Fire Prevention Association. In addition, hazardous materials accident response services at the facility may be required based on the type of wastes handled or the location of the facility.
(d) Flood Hazard Areas. Residual repositories are prohibited in areas subject to inundation by floods with a one-hundred year return frequency, and shall not be located in areas subject to flash floods and debris flows.
All other facilities shall avoid locating in flood plains or areas subject to flash floods and debris flows unless they are designed, constructed, operated, and maintained to prevent migration of hazardous wastes in the event of inundation.
(e) Proximity to Active or Potentially Active Faults. All facilities are required to have a two hundred foot (200′) setback from a known active earthquake fault.
(f) Slope Stability. Residuals repositories are prohibited in areas of potential rapid geologic change.
All other facilities shall avoid locating in areas of potential rapid geologic change unless containment structures are designed, constructed, and maintained to preclude failure as a result of such changes.
(g) Subsidence/Liquefaction. Residuals repositories are prohibited from locating in areas of potential rapid geologic change.
All other facilities shall avoid locating in areas of potential rapid geologic change unless containment structures are designed, constructed, and maintained to preclude failure as a result of such changes.
(h) Aqueducts and Reservoirs. All facilities shall locate in areas posing minimal threats to the contamination of drinking water supplies contained in reservoirs and aqueducts.
(i) Discharge of Treated Effluent. Facilities generating wastewaters shall be located in areas with adequate sewer capacity to accommodate the expected wastewater discharge. If sewers are not available, the site should be evaluated for ease of connecting to a future sewer or for the feasibility of discharge directly into a septic system or private treatment facility.
(j) Proximity to Supply Wells and Well Fields. A residuals repository shall locate away from the cone of depression created by pumping a well or well field ninety (90) days. Location is preferred where the saturated zone predominantly discharges to non-potable water without any intermediate withdrawals for public water supply.
All other hazardous waste facilities shall locate outside the cone of depression created by pumping a well field for ninety (90) days unless an effective hydrogeologic barrier to vertical flow exists.
(k) Depth of Groundwater. Residuals repositories and facilities with subsurface storage and/or treatment are prohibited in areas where the highest anticipated elevation of underlying groundwater is five feet (5′) or less from the lowest subsurface point of the facility. At all facilities, the foundation of all containment structures at the facility must be capable of withstanding hydraulic pressure gradients to prevent failure due to settlement, compression, or uplift as certified by a California Registered Civil Engineering Geologist.
(l) Groundwater Monitoring. Residuals repositories and facilities with subsurface storage and/or treatment must develop a program that successfully satisfies the RWQCB permit requirements for groundwater monitoring.
Facilities which handle liquids should be located where groundwater flow is in one direction with no vertical interformational transfer of water.
(m) Major Aquifer Recharge Area. Residuals repositories are prohibited within any area known to be, or suspected of, supplying principal recharge to a regional aquifer.
Facilities with subsurface storage or treatment must be located at least one-half (½) mile away from potential drinking water sources.
All other facilities located in areas known to be, or suspected of, providing recharge to an existing water supply well shall provide for increased spill containment and inspection measures.
(n) Soil Permeability. Soil permeability requirements for disposal and subsurface treatment and storage facilities shall conform to those required by the State Water Resources Control Board. All other above ground facilities shall have engineered structural design features common to other types of industrial facilities. These features shall include spill containment and monitoring devices.
All other facilities may be located in areas where surficial materials are principally highly permeable materials if adequate spill containment and inspection measures are employed.
(o) Existing Groundwater Quality. Residuals repositories are allowed only where the uppermost water-bearing zone or aquifer is presently mineralized (by natural or human-induced conditions) to the extent that it could not reasonably be considered for beneficial use.
(p) Non-Attainment Areas. All facilities with air emissions locating in non-attainment areas and emitting air contaminants in excess of established limits will require pre-construction review under new source review requirements, and the obtaining of a permit to construct and a permit to operate from the Air Pollution Control District.
(q) Prevention of Significant Deterioration (PSD) Area. All facilities with air emissions locating in the region which are classified under the PSD regulations as major stationary sources will be required to submit to pre-construction review and apply best available control technology.
(r) Wetlands. All types of facilities are prohibited from locating in wetlands.
(s) Proximity to Habitats of Threatened and Endangered Species. Facilities are prohibited in habitats of threatened or endangered species unless the developer can demonstrate that the habitat will not be disturbed and the survival of the species will not be threatened.
(t) Recreation, Cultural, or Aesthetic Areas. All facilities shall be prohibited in areas of recreation, cultural, or aesthetic value as determined by the Director of Community Development, Planning Commission and City Council.
(u) Areas of Potential Mineral Deposits. Residuals repositories shall not be located on or near lands classified as containing mineral deposits of significance by California's Mineral Land Class Maps and Reports.
All other facilities shall avoid locating on near lands classified as containing mineral deposits of significance if the use or preservation of the mineral deposit would be restricted or prevented.
(v) Proximity to Areas of Waste Generation. Subject to other standards and criteria described herein, all facilities shall be located in areas best suited for providing services to the hazardous waste generators of the City. Facilities which will primarily serve generators from outside the City must demonstrate why the facility cannot be located closer to the points of hazardous waste generation to be serviced.
(w) Distance From Major Transportation Routes. Distance traveled on minor roads shall be kept to a minimum. Facility proponents shall be required to pay user fees to ensure proper road construction and maintenance necessary to accommodate the anticipated increase in traffic due to the facility.
(x) Structures Fronting Minor Routes. Facilities shall be located such that any minor routes to and from State or Interstate divided highways to or from the facility are used primarily by trucks, and the number of nonindustrial structures (homes, hospitals, schools, etc.) along such routes is minimal.
The facility proponent shall evaluate the "population at risk" based on the Federal Highway Administration's Guidelines for applying criteria to designate routes for transporting hazardous materials. The population at risk factor should not exceed that for existing facilities and sites with lower factors are preferred.
(y) Capacity vs. Average Daily Traffic of Access Roads. The changes in the ratio of route capacity to average annual daily traffic shall be negligible after calculating the number of trucks on the major and minor routes expected to service the facility.
(z) Consistency with the General Plan. The proposed facility shall be consistent with all general plan requirements, zoning ordinances, and other planning actions or policies that were in place at the time the application was deemed complete.
(aa) Changes in Real Property Values. The project proponent shall fund an independent study of the effect of the facility on real property values within the City. Both the project proponent and the Community Development Agency shall agree beforehand upon the scope of the study and who will conduct it.
(bb) Direct Revenue to Local Jurisdictions. The City will explore, review, and impose appropriate taxes, user fees, and other revenue or compensation options.
(cc) Changes in Employment. The project proponent shall fund an independent study of anticipated changes in employment if the facility is sited. The developer and the City shall agree beforehand on the scope of the study and who will conduct it.
