Section 0400-12-02-.03 - SITING CRITERIA FOR NEW COMMERCIAL HAZARDOUS WASTE MANAGEMENT FACILITIES

(1) General

(a) Purpose/Scope

1. Paragraph (2) of this rule establishes the criteria which define an acceptable site for a new commercial facility in Tennessee. These criteria provide a basis upon which permit applications for facilities will be evaluated. The differences between treatment, storage and disposal facilities are incorporated into a ''unit'' approach (i.e. ''land-based units'' and ''non-land-based units'). This approach rather than a ''facility'' approach was selected in recognition that a ''facility'' may include several different ''units'' of various types and functions. The land-based/non-land-based distinction was selected over a storage/treatment/disposal distinction when it became apparent that the structural nature of a unit was much more important than its intended use function in evaluating the risks the unit poses to human health and the environment in a given locational setting. For example, a surface impoundment holding hazardous wastes presents much the same hazards to surrounding persons and properties whether it is holding the wastes for purposes of storage, treatment, or disposal. In effect, the land-based/non-land-based approach distinguishes between certain types of storage/treatment units and others, with disposal units always considered land-based units. This is consistent with the approach taken in establishing the hazardous waste management facility standards promulgated in Chapter 0400-12-01, Hazardous Waste Management.

2. Paragraph (3) of this rule establishes the criteria by which the permit applicant's previous operating history in the field of solid or hazardous waste management will be evaluated.

3. Paragraph (4) of this rule establishes the documentation deemed necessary in order for the department to determine compliance with the criteria of paragraphs (2) and (3). These information requirements must be met in order for a person to be permitted to operate a new commercial facility in Tennessee.

(b) Applicability

1. Except as provided in part 4 of this subparagraph, the requirements of this rule apply as specified to the following hazardous waste management facilities or units, and the owner(s) and operator(s) thereof:

(i) All new commercial facilities that are required to apply for a permit pursuant to Rule 0400-12-01-.07;

(ii) All new hazardous waste management units to be added to commercial facilities which previously received a permit pursuant to this rule and Rule 0400-12-02-.02;

(iii) New land-based and thermal treatment units to be added to existing or proposed commercial facilities which do not meet the definition of ''new commercial facility'' at Rule 0400-12-02-.01(2)(a).

(iv) Those permitted non-commercial facilities whose permit is modified to allow commercial operation.

2. Except as provided in subpart 1(iii) of this subparagraph, the requirements of this rule shall not apply to:

(i) Those commercial facilities or units which were in existence and had a permit and/or interim status on July 1, l989;

(ii) Proposed commercial facilities or units which do not meet the definition of ''new commercial facility'' at Rule 0400-12-02-.01(2)(a).

3. The requirements of this rule shall not apply to those commercial facilities which are seeking a new permit to replace an expiring permit unless subpart 1(ii) or (iii) of this subparagraph also apply.

4. With respect to the addition of new units to permitted commercial facilities;

(i) The requirements of paragraph (3) and subparagraphs (4)(q) and (r) of this rule shall not apply, and

(ii) The other requirements of this rule shall apply only to those units for which a permit is required pursuant to Rule 0400-12-01-.07.

(c) Relationship to Rules 0400-12-01-.06 and 0400-12-01-.07(5)

1. The criteria of paragraphs (2) and (3) of this rule shall apply to new commercial facilities in addition to the facility standards of Rule 0400-12-01-.06. In the event of any overlap or conflict between these criteria and standards, the more stringent requirements shall apply.

2. The information required in paragraph (4) of this rule must be submitted as part of, or along with, the Part B permit application described in Rule 0400-12-01-.07(5). However, those portions of the documentation submitted in compliance with paragraph (4) of this rule must be clearly identifiable and separable.

(d) Definition of ''Existing''

The distance criteria of this rule shall apply to those wetlands, wells, streams, intake points, parks, structures and other protected entities as those entities exist on the date of original Part A application submittal (exclusive of voided Part A applications - see Rule 0400-12-02-.02(2)(a)) for a proposed new commercial facility. The term ''existing'' is used in this rule to denote this.

(2) Siting Criteria

(a) Floodplains

1. New land-based units shall not be located in 100-year floodplains.

2. Owners or operators of new non-land-based units located in 100-year floodplains must demonstrate, to the satisfaction of the commissioner, that the unit is designed, constructed, operated, and maintained to prevent the washout of any hazardous waste by a 100-year flood, and to enable the unit to withstand the effects of erosion during its active life. New units will be prohibited in locations where the owner or operator is unable to make these demonstrations.

3. Owners or operators of new units located in the 100-year floodplain must further demonstrate that maintenance activities will repair controls after a flood.

4. New non-land-based units shall not be located in the historical migration zone of 100-year floodplains.

5. As used in this subparagraph:

(i) ''100-year flood'' means a flood discharge that has a one-percent chance of being equaled or exceeded in any given year.

(ii) ''100-year floodplain'' means any land area which is subject to a one percent or greater chance of flooding in any given year from any source.

(iii) ''Historical Migration Zone'' means the area within any 100-year floodplain as defined by the Federal Emergency Management Agency (FEMA) on their Flood Insurance Rate Maps (FIRMs) having a Flood Hazard Factor code greater than or equal to A7.

(iv) ''Flood Hazard Factor'' (FHF) is, for a given reach of any body of water, the weighted difference between the 10- and 100-year water surface elevations expressed to the nearest one-half foot; FHFs have been calculated by FEMA for the vast majority of flood-prone areas of the U.S.

(v) ''Washout'' means the movement of hazardous waste from hazardous waste management unit as a result of a flood event.

(b) Wetlands

1. New land-based and non-land-based units shall be prohibited in or adjacent to wetlands.

2. As used in part 1 of this subparagraph:

(i) ''Adjacent'' to a wetland means bordering, contiguous, neighboring, or hydrologically interconnected via surface water or ground water. Adjacent wetlands include, but are not limited to, those areas that are separated from other waters of the states by man-made dikes, berms, or barriers, natural river berms, and beach dunes.

(ii) ''Wetland(s)'' means those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support a prevalence of vegetation typically adapted to life in saturated soil conditions. Wetlands include, but are not limited to, swamps, marshes, bogs, and similar areas.

(c) Seismic Considerations

1. New land-based and non-land-based units to be located in the vicinity of a fault along which movement during the Holocene has occurred shall be located no closer than 200 feet (61 meters) to the fault, unless a site-specific demonstration under part 3 of this subparagraph is made.

2. For new land-based and non-land-based units that will be located within 3,000 feet of a lineament, owners or operators shall demonstrate, to the satisfaction of the commissioner, that no faults along which movement during the Holocene has occurred are present within 200 feet of the unit. This is the minimum distance specified by the commissioner, unless a site- specific demonstration is made under part 3 of this subparagraph.

3. In cases where the owner or operator or the regulatory authority believes that the 200 foot distance is either larger than necessary or not large enough to protect human health and the environment, they may do site-and regional-specific studies to demonstrate, to the satisfaction of the commissioner, that the zone of deformation is smaller or larger than 200 feet. This comprehensive site and regional investigation must show that any movement along the Holocene fault and in the adjacent zone of deformation will not disrupt the contents of any unit or damage the structural integrity of any unit, or in any way threaten human health or the environment.

4. For new land-based and non-land-based units to be located in a seismic impact zone, as determined by the owner or operator based on approved seismic risk maps or methods, the owner or operator shall demonstrate, to the satisfaction of the commissioner, that:

(i) The structural integrity of the unit will allow it to withstand damage caused by any ground shaking, liquefaction, or seismic wave motion exceeding the predicted maximum horizontal acceleration for the corresponding seismic impact zone, or

(ii) There is less than 10 percent probability that the maximum horizontal acceleration at the site will exceed 0.10g in 250 years.

5. As used in parts 1 through 4 of this subparagraph:

(i) ''Displacement'' means the relative movement of any two sides of a fault measured in any direction.

(ii) ''Fault'' means a fracture or zone of rock fracturing in any material along which there has been an observable amount of displacement of the sides relative to one another.

(iii) ''Holocene'' means the most recent geologic epoch within the Quaternary Period, from the end of the Pleistocene Epoch to the present, including the last 10,000 - 12,000 years.

(iv) ''Lineament'' means an arranged topographical line or series of lines on the earth's surface, which may be straight or gently curved, and of sufficient length as to indicate or reflect the alignment of buried structural configurations (these features may be indicated by depressions, uplifts, changes in stream course, or changes in vegetation, and may denote the presence of faults, folds, or joints).

(v) ''Horizontal ground acceleration'' is the maximum change in velocity over time relative to horizontal movement of the earth's surface as measured at a particular point during an earthquake. This is a parameter used to specify the hazard posed to structures caused by ground motion during an earthquake. This information can be used to calculate the acceleration values for any particular area and is derived from equations relating to the area's geology and its past seismicity. Calculated acceleration values are plotted on a map and contoured to delineate regional variations in predicted estimates of maximum ground acceleration. Such maps are available in Open-File Report No. 82-1033 of the U.S. Geological Survey.

(vi) ''Seismic impact zone'' means an area where the probability is greater than or equal to 10 percent that the maximum horizontal acceleration in lithified earth material will equal or exceed 0.10g (expressed as a percentage of the earth's gravitational pull (g), in 250 years.

(vii) ''Structural component(s)'' means any constituent, part, element, or ancillary device used in the construction and operation of a land-based or non-land-based unit.

(viii) ''Zone of deformation'' means the area adjacent to and surrounding a Holocene fault which is subject to structural deformation as a result of movement along the fault. Geologic features that may occur in a zone of deformation include splay or satellite faults, gauge zones, en echelon fault clusters, and complexly deformed strata.

(i) Owners and operators of new land-based and non-land-based units to be located in areas where poor foundation conditions exist at, beneath, adjacent to, or in the area of the unit shall demonstrate, to the satisfaction of the commissioner, that the problem conditions can and will be mitigated, or have been mitigated, using appropriate engineering methods.

(ii) As used in subpart (i) of this part, ''poor foundation conditions'' means those areas where features exist which indicate that a natural or man-induced event may result in inadequate foundation support for the structural components of a land-based or non-land-based unit.

2. Areas Susceptible to Mass Movement

(i) Owners and operators of new land-based and non-land-based units to be located in areas susceptible to mass movement shall demonstrate, to the satisfaction of the commissioner, that appropriate engineering measures will be applied to ensure unit structural integrity and to mitigate the threats posed to human health and the environment by mass movement.

(ii) As used in subpart (i) of this part, ''areas susceptible to mass movement'' means those areas of influence (i.e., areas characterized as having an active or substantial possibility of mass movement) where the movement of earth material at, beneath, or adjacent to the unit, because of natural or man-induced events, results in the downslope transport of soil and rock material by means of gravitational influence. Areas of mass movement include, but are not limited to, landslides, avalanches, debris slides and flows, creep, solifluction, block sliding, rock fall, and slump. As a minimum those areas identified on the Geological Hazards Map of Tennessee (published in 1977 by the Tennessee Department of Conservation and the Tennessee State Planning Office) as subject to mass movements, shall be so considered.

(iii) As used in subpart (i) of this part, ''structural integrity'' means the ability of a unit to withstand physical forces exerted upon designed components, ancillary devices, and containment structures (e.g., liners, dikes) of the unit.

(III) A geotechnical and hydrogeologic investigation of the site as required by part (4)(h)1 of this Rule shows that the site is stable within Holocene time, and that subsidence into or collapse of subsurface solution cavities as a consequence of instability caused by liquefaction of overburden or by the presence of subsurface voids will not occur.

(ii) New non-land-based units shall not be located in a karst terrain unless the owner or operator demonstrates, to the satisfaction of the commissioner, that:

(I) The site hydrogeologic characterization requirements of part (4)(h)1 of this rule have been met, and

(II) A geotechnical and hydrogeologic investigation of the site as required by part (4)(h)1 of this rule shows that the site is stable within Holocene time and subsidence into or collapse of subsurface solution cavities as a consequence of instability caused by liquefaction of overburden or by the presence of subsurface voids will not occur, or

(III) Where the requirement of item (II) of this subpart cannot be met, that appropriate engineered measures are applied to ensure the unit's structural integrity and to contain, mitigate, or eliminate the adverse effects to human health and the environment that may occur as a result of locating in karst terrain.

(iii) Owners or operators of new units located in a karst terrain that meet the demonstration requirements specified in subparts (i) and (ii) of this part shall design, construct, operate, and maintain the unit in a manner such as to prevent any adverse impacts on human health and the environment as a consequence of the unit's location in karst terrain.

(iv) As used in subparts (i) through (iii) of this part, ''karst terrain'' means a specific type of topography that is formed by dissolving or solution of carbonate formations, such as limestone or dolomite; it is characterized by closed depressions or sinkholes, caves, sinking and reappearing streams, and/or underground conduit drainage flow.

(e) Ground water

1. Complex Hydrogeology

(i) New land-based units are prohibited in areas where the owner or operator cannot demonstrate, to the satisfaction of the commissioner:

(I) That the hydrogeology of the site can be adequately characterized. The characterization shall include the rate and direction of ground water flow within the uppermost aquifer and all interconnected aquifers using a ground water flow net (or equivalent hydrogeologic model on a local scale as specified under part (4)(i)1 of this rule);

(II) Compliance with the ground water monitoring requirements under Rule 0400-12-01-.06(6); and

(III) The technical practicability of a corrective action program at the site, based on the availability of current or new and innovative technologies that could practicably achieve ground water remediation. The demonstration shall specify how a corrective action response will be effectively implemented to remediate a release to ground water within the facility property boundary and shall illustrate all the factors that are necessary to be in compliance with the corrective action requirements under Rule 0400-12-01-.06(6).

(ii) Owners or operators of new land-based units that meet the requirements for an exemption from ground water monitoring/correction requirements as specified under Rule 0400-12-01-.06(6)(a) 2 are exempt from items (i)(I) and (i)(II) of this part.

2. High-Resource-Value Ground Waters

(i) New land-based units located in vulnerable hydrogeologic settings overlying high-resource-value ground waters or the recharge zone of high-resource-value ground waters are prohibited unless the following conditions are met by the owner or operator:

(I) An extension of the post-closure-care period is granted by the commissioner for such time as is necessary to protect human health and the environment;

(II) The unit contains only waste that has been treated using Best Demonstrated Available Technology (BDAT) as required under Rule 0400-12-01-.10; and

(III) The owner or operator can demonstrate, to the satisfaction of the commissioner, that health-based criteria for those hazardous wastes or hazardous constituents of concern will not be exceeded beyond the limit of the waste management area in the event of a release, or that the owner or operator can implement an effective corrective action program within the time necessary to prevent contamination in the underlying aquifer from moving beyond the facility property boundary and endangering human health and the environment. Health-based criteria are:

I. Maximum contaminant levels (MCLs) promulgated under Section 141.2 of the Safe Drinking Water Act ( 40 CFR Part 141 Subpart B), or

II. For hazardous constituents for which MCLs have not been promulgated, a concentration which satisfies the following criteria, assuming exposure through consumption of the water contaminated with the hazardous constituent:

A. Is derived in a manner consistent with U.S. Environmental Protection Agency guidelines for assessing the health risks of environmental pollutants (51 FR 33992, 34006, 34014, 34028), and

B. Is based on scientifically valid studies conducted in accordance with the Toxic Substances Control Act (TSCA) Good Laboratory Practice Standards ( 40 CFR Part 792), or equivalent, and

C. For carcinogens, represents a concentration associated with an excess upper bound lifetime cancer risk of 1x10-6 due to continuous constant lifetime exposure, and considers the overall weight of evidence for carcinogenicity, and

D. For systemic toxicants, represents a concentration to which the human population (including sensitive subgroups) could be exposed on a daily basis that is likely to be without appreciable risk of deleterious effects during a lifetime.

(ii) The commissioner shall extend the unit post-closure-care period as specified under Rule 0400-12-01-.06(7)(h) 1 for new land-based units in vulnerable hydrogeologic settings overlying ground waters other than high-resource-value ground waters for such time as is necessary to protect human health and the environment.

3. Corrective Action Buffer Zone

(i) Owners or operators of new land-based units shall establish a dedicated buffer zone between the unit and the facility property boundary adequate to ensure that ground water time of travel, measured along a flow line at least 100 feet in length and originating at the base of the unit, allows adequate time to implement the corrective action response necessary to remedy a hazardous waste release to ground water and to mitigate, contain, or eliminate the release within the facility property boundary. Calculation of the ground water time of travel shall be made as specified under item (4)(i)2(iii) of this rule.

(ii) Owners and operators of new land-based units that cannot establish a dedicated buffer zone at their site that fulfills the requirements under subpart (i) of this part are prohibited from constructing their facility at that particular site.

(iii) A dedicated buffer zone as required under subpart (i) of this part shall meet the following criteria:

(I) It shall consist of an area of land between the unit and the facility property boundary that is owned by the owner or operator and serves as a separation distance between the unit and facility property boundary. The buffer zone shall be used for corrective action and not for the treatment, storage, or disposal of hazardous waste;

(II) It shall serve as a buffer zone for as long as hazardous waste or hazardous constituents remain in the unit, and

(III) It shall be recorded as a notation on the facility property deed as a dedicated portion of the facility property for the sole purpose for which it is intended as specified under items (I) and (II) of this subpart.

4. Definitions

As used in parts 1 through 3 of this subparagraph:

(i) ''Areas of complex hydrogeology'' include, but are not limited to, karst terrains where ground water flow occurs through conduits and along bedding planes and fractures enlarged by dissolution of the rock; fractured rock formations (joints and faults; excludes self-healing fractures); irregularly stratified geologic deposits (e.g., certain fluvial and glacial deposits); mixed hydrogeologic regimes (e.g., certain glacial deposits overlying fractured crystalline bedrock); folded areas where flow paths may be contorted and recharge zones where background water quality cannot be determined.

(ii) ''Areas of vulnerable hydrogeology'' are sites where ground water is particularly susceptible to contamination in the event of a release of hazardous waste or hazardous constituents from a hazardous waste unit. Areas of vulnerable hydrogeology are determined by calculating the time of travel (TOT) of ground water measured along a 100-foot flow line originating at the base of the land-based unit. Procedures for calculating the ground water time of travel are described in EPA statutory interpretive guidance document no. EPA 530-SW-86-0228 entitled, 'Criteria for Identifying Areas of Vulnerable Hydrogeology Under the Resource Conservation and Recovery Act,'' Interim Final, July l986.

(iii) ''Flow net'' is a graph of flow lines and equipotential lines used in the study of ground water that represents three-dimensional flow through porous media. Procedures for constructing a ground water flow net are described in EPA statutory interpretive guidance document no. EPA 530-SW-86-0228 entitled, ''Criteria for Identifying Areas of Vulnerable Hydrogeology Under the Resource Conservation and Recovery Act,'' Interim Final, July, l986. Equivalent hydrogeologic models may be used in place of a flow net, subject to the approval of the commissioner.

(iv) ''High-Resource-Value Ground waters'' are defined as those ground waters that are characterized by either of the following factors: the ground water is irreplaceable because no reasonable alternative source of drinking water is available to substantial populations, or the ground water is ecologically vital because it provides the base flow for a particularly sensitive ecological system that, if polluted, would destroy a unique habitat.

(v) ''Recharge Zone'' is defined as that part of a geologic unit, which is an aquifer, where ground water is absorbed and added to the zone of saturation; from this area the ground water can migrate through the geologic unit under the influence of existing hydraulic gradients.

(vi) ''Release'' means any spilling, leaking, pouring, emitting, emptying, discharging, injecting, pumping, escaping, leaching, dumping, or disposing of hazardous waste or hazardous constituents into the environment including the abandonment or discarding of containers, barrels, and other closed or open receptacles containing hazardous waste or hazardous constituents.

5. Vertical Buffer Zones

(i) New land-based units shall be located and constructed such that there is, between the bottom of the unit's liner system and the seasonally high water elevation in the uppermost saturated zone underlying the unit, a buffer layer of natural and/or emplaced soil meeting one of the following descriptions:

(I) Ten feet thick, with a saturated hydraulic conductivity of 1x10-5 centimeters per second, or

(II) Five feet thick, with a saturated hydraulic conductivity of 1x10-6 centimeters per second.

(ii) New non-land-based units shall be located and constructed such that there is, between the bottom of the unit's secondary containment system and the seasonably high water elevation in the uppermost saturated zone underlying the unit, one of the following:

(f) Drinking Water Supplies

1. Except as provided in part 4 of this subparagraph, new land-based units shall be located at least:

(i) Outside the lateral limits of the theoretical cone of depression (calculated at the design capacity of the existing pumping system) for any public or private drinking water supply well which withdraws water from the uppermost aquifer or any underlying aquifer which is hydraulically connected to the uppermost aquifer within this cone of depression; and

(ii) Two times the corrective action buffer zone distance calculated pursuant to part (e)3 of this paragraph from existing private drinking water supply wells; and

(iii) Five times the corrective action buffer zone distance calculated pursuant to part (e)3 of this paragraph from existing public water supply wells; and

(iv) Two times the corrective action buffer zone distance calculated pursuant to part (e)3 of this paragraph from any stream segments that are, relative to existing private drinking water supply intakes:

(I) For impounded stream segments, within one mile upstream or downstream, and

4. The set-back requirements of parts 1 through 3 of this subparagraph shall not apply to those water supply wells and intakes used to supply drinking water solely to the hazardous waste management facility itself, providing such are monitored on at least a quarterly basis and other measures taken as necessary to ensure a safe drinking water supply for employees.

(g) Surface Waters

1. New land-based units shall be set back from streams, lakes, ponds, reservoirs, and other surface water bodies (except those constructed as part of the facility) by a distance at least equal to the corrective action buffer zone distance calculated pursuant to part (e)3 of this paragraph.

To ensure that human enjoyment of scenic, cultural, and recreational areas are not impaired, new commercial facilities must:

1. Be screened from sight, or at sufficient distance as to be indistinguishable from the surroundings, from the boundaries of such areas, unless the owner or operator demonstrates to the satisfaction of the commissioner that the facility and operations are consistent with the visual character of other surrounding structures and activities; and

2. Be located, configured, designed, constructed, and/or operated such that driveways, transport vehicle parking areas, loading and unloading areas, and other areas where mechanized (or other) noisy operations may take place do not cause a significant increase in the noise level at the boundaries of scenic, cultural, and recreational areas.

(i) Endangered Species

A new commercial facility must be located, designed, constructed, operated, maintained, closed, and (for disposal units) cared for during the post-closure care period in a manner that does not:

1. Cause or contribute to the taking of any endangered or threatened species of plants, fish, or wildlife; or

2. Result in the destruction or adverse modification of the critical habitat of endangered or threatened species.

(j) Distances from Other Structures/Areas

This subparagraph establishes criteria governing the location of proposed commercial facilities relative to other structures or areas, which may be impacted. These criteria are designed to minimize incompatibility with the character of the surrounding area, to minimize adverse effects on the value of surrounding areas through impairment of the ability to enjoy or use such structures/areas, and to provide additional protection to public health and safety. These requirements shall not apply to structures which are part of or associated with the facility or which the owner or operator owns.

1. Except as provided by part 5 of this subparagraph, new commercial facilities shall be at least 1,500 feet from the actual location of the hazardous waste facility measured as the shortest distance between the permitted hazardous waste management unit and the property line of existing structures/areas identified in part 3 of this subparagraph. New commercial facilities must also be screened from sight, or at a sufficient distance (not less than 1,500 feet) as to be indistinguishable from the surroundings and from existing structures/areas as identified in part 3 of this subparagraph, unless the owner or operator demonstrates to the satisfaction of the Commissioner that the facility and operations are consistent with the visual character of other surrounding structures and activities.

2. New commercial facilities must be located, configured, designed, constructed, and/or operated such that transport vehicle parking areas (excluding driveways/access roads), loading and unloading areas, and other areas where mechanized (or other) noisy operations may take place do not cause a significant increase in the noise level at existing structure/area boundaries as identified in part 3 of this subparagraph.

3. The requirements of parts 1 and 2 of this subparagraph apply to:

(i) Structures which are hospitals, nursing homes, or other institutions which house populations of the aged or sick;

(ii) Structures which are schools, child-care centers, or other non-residential facilities where children spend substantial amounts of time, and surrounding areas of associated use (e.g., including playgrounds but excluding driveways and parking areas);

(iii) Structures which are used as residences, and surrounding areas of associated use (e.g., including yards but excluding driveways, parking areas, farmlands, woodlots, etc.);

(iv) Structures which are churches, and surrounding areas of associated use (e.g., including yards, playgrounds, and picnic areas, but excluding driveways and parking areas); and

(v) Structures which are used for public service, commercial retail, or commercial service purposes and frequented by the public.

4. New non-land based units and other areas/units (other than land-based units) where hazardous wastes are managed (including transport vehicle parking lots but excluding driveways and access roads) shall be located at least 50 feet from the facility property line.

5.
