     5.  If toxic materials are known or suspected by the Department to be present in a water, testing for toxicity may be required to determine compliance with the provisions of this section and effluent limitations. The Department may specify the method of testing to be used. The failure to determine the presence of toxic materials by testing does not preclude a determination by the Department, on the basis of other criteria or methods, that excessive levels of toxic materials are present.

     6.  Radioactive materials attributable to municipal, industrial or other controllable sources must be the minimum concentrations that are physically and economically feasible to achieve. In no case must materials exceed the limits established in the 1962 Public Health Service Drinking Water Standards (or later amendments) or 1/30th of the MPC values given for continuous occupational exposure in the “National Bureau of Standards Handbook No. 69.” The concentrations in water must not result in accumulation of radioactivity in plants or animals that result in a hazard to humans or harm to aquatic life.

     7.  Wastes from municipal, industrial or other controllable sources containing arsenic, barium, boron, cadmium, chromium, cyanide, fluoride, lead, selenium, silver, copper and zinc that are reasonably amenable to treatment or control must not be discharged untreated or uncontrolled into the waters of Nevada. In addition, the limits for concentrations of the chemical constituents must provide water quality consistent with the mandatory requirements of the 1962 Public Health Service Drinking Water Standards.

     8.  The specified standards are not considered violated when the natural conditions of the receiving water are outside the established limits, including periods of extreme high or low flow. Where effluents are discharged to such waters, the discharges are not considered a contributor to substandard conditions provided maximum treatment in compliance with permit requirements is maintained.

     (a) An assessment of the contaminated groundwater is conducted and indicates that the level of contamination is consistently below the action level for that water established pursuant to NAC 445A.22735;

     (b) A test of asymptotic concentrations specified in paragraph (c) is not appropriate, as determined by the Division based on the nature of the treatment used or the conditions at the site which limit the effectiveness of any available treatment, and the owner or operator complies with the conditions for the termination of remediation set forth in an approved plan of corrective action or an approved amendment to such a plan; or

     (c) After the groundwater is treated for not less than 1 year, the concentration of dissolved constituents in the water, measured monthly, fits a curve that is substantially linear and approaches zero slope at the final portion of the curve. The curve must be established using the following equation:

 

C   =   Cf   +   Coe^-kt

 

Where:    “C”   means the concentration of the contaminant at “t” in micrograms per liter.

 

               “Cf” means the final concentration of the contaminant in micrograms per liter which the curve approaches asymptotically.

 

               “Co” means the difference between the final concentration of the contaminant and the concentration of the contaminant at time zero in micrograms per liter.

 

               “e”    means the base of the natural log or 2.718.

     (a) The quality of surface water is lowered below that allowed by NRS 445A.565.

     (b) For groundwater:

          (1) The concentration of a constituent exceeds the greater of:

               (I) A state or federal regulation prescribing standards for drinking water; or

               (II) The natural background concentration of the regulated drinking water constituent; or

          (2) The concentration of WAD cyanide exceeds 0.2 mg/L.

Ê The Department may establish a numerical limit for any constituent not regulated by subparagraphs (1) and (2) which may reasonably be expected to be discharged by the facility in sufficient volume and concentration to cause an adverse impact on human health.

     (c) The quality of those waters of the State which already exceed the criteria established by subsection 2 is lowered to a level that the Department finds would render those waters unsuitable for the existing or potential municipal, industrial, domestic or agricultural use.

     2.  The Department may exempt a body of groundwater or portion thereof from the standards established in subsection 1 if the request for an exemption to the groundwater standards and the supporting information is submitted as part of the application for the permit. The following criteria will be considered by the Department in determining whether to exempt a potentially impacted body of groundwater from the standards in subsection 1:

     (a) The impacted groundwater does not currently serve as a source of drinking water and because of the following reasons the groundwater will not serve as a source of drinking water:

          (1) The groundwater produces a mineral, hydrocarbon or geothermal fluid which the applicant can demonstrate to the satisfaction of the Department exists at a concentration that is expected to be capable of commercial production and that releases by the facility will not affect this production;

          (2) The groundwater is situated at a depth or location which makes recovery of water for drinking economically or technologically impractical; or

          (3) It would be economically or technologically impractical to render the water fit for human consumption; or

     (b) The total dissolved solids in the groundwater is more than 10,000 milligrams per liter and the groundwater is not reasonably expected to become a supply of drinking water.

     (e) The fluid management system must be designed for the operating life of the system to be functional for 5 years after the projected operating life of the process component and permanent closure period.

     (f) The design of the process components must take into consideration the proposed range of operating conditions for each component and the history of seismic events at the site in order to preclude any differential movement or shifting of the subbase, liner or contained material which endangers primary or secondary containment integrity.

     2.  If the final plan for permanent closure of a facility that is required pursuant to NAC 445A.447 has not been approved by the Department before September 1, 2018, the following minimum criteria apply for the permanent closure period:

     (a) All process components must be designed or modified to withstand the runoff from a 24-hour storm event with a 500-year recurrence interval.

     (b) The primary fluid management system must be designed or modified to be able to remain fully functional and fully contain all fluids, including all accumulations resulting from a 24-hour storm event with a 500-year recurrence interval.

The federal public notification regulations, 40 C.F.R. §§ 141.201 to 141.211, inclusive, including Appendices A, B and C, as adopted by reference in NAC 445A.4525, provide the criteria for the tier assignment for each specific violation or situation, and the requirements for the content, form, manner and frequency of the notice.

     (c) Each public water system shall provide public notice to persons served by the water system in accordance with this section. Public water systems that sell or otherwise provide drinking water to other public water systems are required to give notice to the owners or operators of those systems, who are then responsible for providing public notice to the persons they serve. If a public water system has a violation in a portion of the distribution system that is physically or hydraulically isolated from other parts of the distribution system, the Division or the appropriate district board of health may allow the system to limit distribution of the public notice to only those persons served by that portion of the system which is out of compliance. Permission by the Division or the appropriate district board of health for limiting distribution of the notice must be granted in writing.

     (d) A copy of the notice must also be sent to the Division or the appropriate district board of health in accordance with the requirements of 40 C.F.R. § 141.31(d), as adopted by reference in NAC 445A.4525.

     3.  Public notice of a violation of NAC 445A.455 is required pursuant to NRS 445A.940 and as follows:

     (a) When a secondary maximum contaminant level exceeds the levels or units specified in subsection 1 of NAC 445A.455, the public water system shall, within 90 days, collect and analyze three additional samples from the same sample point, but not more than one sample per month. If the average contaminant level of the four samples exceeds the secondary maximum contaminant level, the public water system shall notify the Division or the appropriate district board of health and shall provide notice to the public. The notice must be:

          (1) For community public water systems:

               (I) Published in a newspaper of general circulation in the area served by a system not more than 30 days after the standard is exceeded, or delivered personally or by mail to each person served by the system not more than 30 days after the standard is exceeded; and

               (II) Published and delivered annually thereafter as provided in the annual consumer confidence report prepared pursuant to NAC 445A.4845 if the standard continues to be exceeded.

      NAC 445A.487  Variances: General conditions and procedure for granting. (NRS 445A.855, 445A.860)

     1.  The Commission may grant a variance from a primary drinking water regulation to a public water system which cannot meet a requirement respecting a maximum contaminant level specified in such drinking water regulation because of characteristics of the raw water source or sources which are reasonably available to the system. A variance may be issued to a system on the condition that the public water system install the best available technology, treatment techniques or other means which the Commission and the Administrator of the United States Environmental Protection Agency find are reasonably available after taking costs into consideration and based on an evaluation satisfactory to the Commission that indicates that alternative sources of water are not reasonably available to the public water system. Before such a variance may be granted, the Commission must find that the variance will not result in an unreasonable risk to health.

     2.  The Commission may grant a variance to a public water system from any provision of a primary drinking water regulation which requires the use of a specified treatment technique with respect to a contaminant. Before the issuance of such a variance, the public water system must demonstrate to the satisfaction of the Commission that the treatment technique is not necessary to protect the health of persons because of the nature of the raw water source of the system.

     3.  The Commission may grant a variance from a secondary drinking water regulation to a public water system in accordance with the procedures for seeking variances from the Commission.

     4.  Public hearings and other procedures for consideration of requests for variances from NAC 445A.450 to 445A.492, inclusive, must be conducted in accordance with the procedures for seeking variances from the Commission. The Commission will grant a variance from a regulation only if it finds from the evidence presented at the hearing that:

     (a) There are circumstances or conditions which:

          (1) Are unique to the applicant;

          (2) Do not generally affect other persons subject to the regulation;

          (3) Make compliance with the regulation unduly burdensome; and

          (4) Cause a hardship to and abridge a substantial property right of the applicant; and

     (b) Granting the variance:

          (1) Is necessary to render substantial justice to the applicant and enable him or her to preserve and enjoy his or her property right; and

          (2) Will not be detrimental or pose a danger to public health and safety.

Ê Whenever an applicant for a variance alleges that he or she suffers or will suffer economic hardship by complying with the regulation, the applicant must submit evidence demonstrating the costs of his or her compliance with the regulation. The Commission will consider the evidence and determine whether those costs are unreasonable.

     5.  As used in this section, “best available technology, treatment techniques or other means” means technology, techniques and means which are found reasonably available by the Administrator of the United States Environmental Protection Agency and which are identified and applied in accordance with 40 C.F.R. §§ 141.61 to 141.66, inclusive, and 142.61 to 142.65, inclusive, as adopted by reference in NAC 445A.4525.

The use of an advanced wastewater treatment unit may allow for a reduction that is not more than 25 percent in land area, if the design engineer can demonstrate to the satisfaction of the Division or other administrative authority that the on-site sewage disposal system will not adversely impact the local groundwater or surface water.

     3.  An on-site sewage disposal system with projected daily sewage flow greater than:

     (a) Fifteen thousand gallons per day, or which receives flows other than domestic sewage, must obtain an individual permit from the Division or other administrative authority.

     (b) Five thousand gallons per day may be required by the Division or other administrative authority to obtain a groundwater mounding analysis. If required by the Division or other administrative authority, the design engineer shall submit sufficient site-specific data which predicts both the height of the water-table mound that will develop beneath the field and the rate of lateral and vertical flow away from the absorption area. The site will be deemed unsuitable if the data predicts that the water-table mound that will develop beneath the site cannot be maintained 4 feet or more below the bottom of the absorption area or if it is determined that effluent is likely to become exposed onto the ground surface.

     4.  All sewage within an on-site sewage disposal system must be treated and dispersed in a manner approved in accordance with NAC 445A.950 to 445A.9706, inclusive, and cesspools are prohibited.

     5.  A person shall not discharge untreated or partially treated wastewater or septic tank effluent directly or indirectly onto the ground surface or into a deep pit, mine shaft, abandoned well or other waters of the State. Such discharge constitutes a public health hazard and is prohibited.

     6.  A person shall not discharge into any on-site sewage disposal system cooling water, air-conditioning water, water softener brine, swimming pool or hot tub water, groundwater, oil, hazardous materials, roof drainage or other aqueous or nonaqueous substances that are detrimental to the performance of the system or to groundwater. Commercial kitchens must provide a grease interceptor, approved by the appropriate local health authority, before discharge to the septic tank or other treatment unit. Laundromats must provide a lint interceptor before discharge into a septic tank or other treatment unit.

     7.  A person shall not connect a commercial facility to an on-site sewage disposal system if the additional flow would result in a greater projected daily sewage flow than that allowed under the permit for the system, unless expressly allowed by the Division or other administrative authority.

     8.  Each on-site sewage disposal system must have adequate capacity to properly treat and disperse the maximum projected daily sewage flow. The projected daily sewage flow must be determined from the table set forth in NAC 445A.9656 or from another source specified by the Division or other administrative authority.

     9.  The owner of an on-site sewage disposal system shall operate and maintain the system in compliance with all permit conditions and applicable requirements set forth in NAC 445A.950 to 445A.9706, inclusive, and shall not create a public health or safety hazard or pollute the waters of the State.

     10.  Any aspect of design, construction, operation or maintenance of an on-site sewage disposal system not addressed in NAC 445A.950 to 445A.9706, inclusive, must meet the most restrictive requirements in the current publication of the Uniform Plumbing Code, adopted by reference in NAC 445A.9592, and any guidelines established by the Division.

     11.  All plumbing fixtures in commercial facilities and other structures from which sewage is or may be discharged must be connected to and discharge into an approved area-wide sewerage system or a permitted on-site sewage disposal system that is not a failing system.

      NAC 445A.9674  Calculation of required size of effluent absorption area. (NRS 445A.425)

     1.  The required size of the effluent absorption area for an on-site sewage disposal system must be calculated based on the long-term acceptance rate of the soil at the site, unless the system uses an elevated mound system or an intermittent sand filter system for effluent absorption. An elevated mound system or an intermittent sand filter system must use the table set forth in NAC 445A.9686 for determining the size of the absorption area. The long-term acceptance rate, as determined by either the percolation rate of the soil or soil texture, must be determined in accordance with the following table:

 

Long-Term Acceptance Rates (LTAR) for Wastewater

Application to Soil Absorption Systems

 

     2.  The absorption area required for an on-site sewage disposal system, unless an elevated mound system or intermittent sand filter system is used, must be calculated as Q/LTAR=A, where:

     (a) “A” is the absorption area required;

     (b) “Q” is the average projected daily sewage flow based on septic tank or other treatment unit size; and

     (c) “LTAR” is the long-term acceptance rate of the soil at the site.

Ê For example, if a 3,000 gallon septic tank is proposed and the site consists of loam with a long-term acceptance rate of 0.7 gallons per square foot per day, the calculation would be 3,000 gallons per day divided by 0.7 gallons per square foot per day for a total required absorption area of 4,286 square feet. Thus, the required septic tank capacity determined from the table set forth in NAC 445A.9656 must be divided by the long-term acceptance rate from the table set forth in this section to determine the minimum absorption area required.

In such a case, an alternative effluent absorption system may be used in accordance with NAC 445A.9678 to 445A.969, inclusive.

     2.  An absorption trench system used in an on-site sewage disposal system must meet the following design and construction criteria:

The aggregate must extend from at least 2 inches above the distribution pipe to at least 12 inches below the distribution pipe. If the trench is more than 6 feet below the finished grade, the aggregate must extend not less than 12 inches below the ground surface to avoid anaerobic conditions in the trench.

     (f) The aggregate in the trench must be covered with untreated building paper, straw with a minimum thickness of 1 inch, geotextile fabric or a similar covering approved by the Division or other administrative authority. The top of the trench must be backfilled with not less than 4 inches or more than 6 inches of soil, and fines must be kept from entering the trench from poorly cleaned gravel or poorly cleaned cover. As used in this paragraph, “fines” means any small, crushed or powdered material which may seriously impair the absorption ability of the aggregate used in an absorption trench.

     3.  The total absorption area of the trench must be determined by measuring the size of the effective area of each sidewall of the trench beneath the distribution pipe. Not more than 4 feet of aggregate below the distribution pipe may be used to calculate the effective area of the sidewall unless approved by the Division or other administrative authority. To determine the required length of the absorption trench to meet the total absorption area requirement for the on-site sewage disposal system as calculated pursuant to NAC 445A.9674, the total absorption area required, in square feet, must be divided by 2 times the depth, in feet, of the aggregate beneath the distribution pipe. The depth of the aggregate must be multiplied by 2 to account for both sidewalls of the trench. For example, if the required absorption area is calculated at 3,000 square feet and the aggregate below the distribution pipe is 4 feet deep, the equation would be 3,000 feet squared/(4 feet x 2) = 375 linear feet of distribution pipe, and thus absorption trench, required.

      NAC 445A.9684  Capping fill trench. (NRS 445A.425)

     1.  Except as otherwise provided in subsection 2, a capping fill trench may be used where conditions relating to high groundwater prohibit the installation of an absorption trench pursuant to NAC 445A.9676.

     2.  A capping fill trench must not be used if the soil in which the capping fill is to be placed is saturated.

     3.  The soil surrounding and beneath the bottom of a capping fill trench must have a percolation rate that is more than 10 minutes per inch but less than or equal to 120 minutes per inch. A capping fill trench must not be installed on a slope that is more than 5 percent with a percolation rate slower than 60 minutes per inch, but may be installed on a slope of not more than 10 percent if the percolation rate is equal to or faster than 60 minutes per inch.

      NAC 445A.9686  Elevated mound system. (NRS 445A.425)

     1.  An elevated mound system consists of a suitable fill material, an absorption area made of coarse aggregate and fill material with a distribution network, and a soil cap. In an elevated mound system, the effluent must be gravity fed, pumped or siphoned into the upper part of the absorption area through a distribution network. The effluent must pass through the aggregate and the fill material, with treatment of the wastewater occurring as it passes through the fill material and the unsaturated zone of the native soil.

     2.  In preparing an elevated mound system, the site must be scarified, except that tree stumps and other herbaceous materials must be left in place after mowing or cutting to prevent excessive alteration of the soil structure. Mound construction must begin immediately after scarification, and each layer of the absorption system must be placed in such a manner as to prevent differential settling and to promote uniform density.

     3.  An elevated mound system must not be constructed on a slope that is:

     (a) More than 6 percent if the soils comprising the slope have percolation rates slower than 60 minutes per inch; or

     (b) More than 12 percent if the soils comprising the slope have percolation rates equal to or greater than 60 minutes per inch.

     4.  Percolation tests must be conducted at the depth estimated by the design engineer as being the point of interface between the native soil and the fill material and at a depth of 20 inches below the surface of the native soil. The size of the required area for the elevated mound system must be based on the slowest percolation rate obtained.

     5.  The basal absorption area of an elevated mound system must be sufficiently large to absorb the wastewater before it reaches the perimeter of the elevated mound. The infiltration rates for determining the size of the basal absorption area are as follows:

 

 

     6.  The absorption area required for an elevated mound system must be determined from the table set forth in subsection 5. In addition, if the site on which the elevated mound system will be located is:

     (b) Sloping, only the area below and down slope from the absorption bed must be used to determine the absorption area of the elevated mound system, calculated as W x (L+S), where:

          (1) “W” is the width of the absorption bed;

          (2) “L” is the length of the absorption bed; and

          (3) “S” is the required side slope of the elevated mound pursuant to subsection 9, as measured from the edge of the absorption bed to the perimeter of the mound.

     7.  At least 4 feet of unsaturated soil or fill material, or any combination thereof, must be maintained between the bottom of the mound system and the top of the seasonal high groundwater or any impervious barrier, including, without limitation, any bedrock. On sloping sites, the depth of unsaturated soil and fill material must be increased to maintain a level bed.

     8.  If practicable, the bed for an elevated mound system must be rectangular with a long axis that is parallel to the contour of the slope to minimize the possibility of seepage from the base of the elevated mound. If the natural soil has a percolation rate that is less than 60 minutes per inch, the bed must be made narrow and extend along the contour of the slope as far as practicable. The bed must be filled at least 9 inches deep with clean, graded aggregate.

     9.  The side slopes of an elevated mound system must extend in a horizontal to vertical ratio that is at least 3 to 1.

     10.  The aggregate in the absorption bed must be covered with untreated building paper, straw with a minimum thickness of 1 inch, geotextile fabric or a similar covering approved by the Division or other administrative authority.

     11.  After placement of the covering required pursuant to subsection 10, the entire absorption bed must be covered with at least 1 foot of topsoil. The topsoil cap, which must be placed at the center of the mound, must maintain a minimum slope of 2 percent away from the crown.

     12.  The following is a diagram of an elevated mound:

The dosing rate must not be less than 4 doses or more than 24 doses per day.

     4.  The vessel containing the sand filter must be watertight, structurally sound, durable and capable of withstanding stress from installation and operational service. The intermittent sand filter system may be placed above grade, partially buried or fully buried depending on site and service specifications and must be justified by the design engineer in the design specifications submitted pursuant to NAC 445A.9614.

     5.  The filter media used in the intermittent sand filter system must consist of washed, durable granular material with less than 1 percent organic matter by weight. The effective size of the filter media must not be less than 0.25 millimeter or more than 1.0 millimeter. The uniformity coefficient of the filter media must be less than 4.

     6.  The depth of the filter media must be at least 24 inches, and the top and bottom surfaces of the filter media must be level.

     7.  The filter media used in the intermittent sand filter system must meet the following criteria:

 

Filter Media Specifications

 

 

Source: ASTM C-33, “Specifications for Fine Aggregate”

 

The filter media must not have more than 45 percent passing any one sieve and retained on the next consecutive sieve of those shown in the table above. The fineness modulus must not be less than 2.3 or more than 3.1. As used in this subsection, “fineness modulus” means the sum of the cumulative percentages retained in the sieve analysis, divided by 100, for the sieve sizes shown in the table above.

     8.  The required size of the intermittent sand filter system depends on the projected daily sewage flow of the on-site sewage disposal system. The maximum wastewater loading rate is 1 gallon per day per square foot of inlet surface at the rated projected daily sewage flow. For example, a system with a flow of 4,000 gallons per day would require a sand filter of at least 4,000 square feet.

     9.  The native soil portion of the absorption system must be designed to ensure that the linear loading rate does not exceed the disposal capability at the site.

     1.  A pressure distribution system may be used in conjunction with any effluent absorption system that uses distribution pipes. A pump must be used to pressurize the pressure distribution system.

     2.  The active dosing volume of a pressure distribution system must be approximately 10 times the total volume of the distribution pipe used in the effluent absorption system.

     3.  A solid delivery pipe which connects the dosing tank to the perforated distribution piping must be placed below the frost line. The delivery pipe must maintain a downward slope from the distribution lines to the dosing tank to ensure drainage between discharges. The use of check valves and other devices that prevent backflow to the pump is prohibited.

     4.  To reduce the potential for plugging and clogging of distribution pipes, the diameter of the discharge hole must be at least 3/8 inch. If an effluent screen is used, the diameter of the discharge hole may be reduced accordingly. The rate of discharge for various-sized holes at various pressures are set forth in the following table:

 

 

     5.  Friction losses in schedule 40 plastic pipe are listed in the following table:

 

 

     6.  Distribution pipes in the pressure distribution system must be looped.
