  4. DEFINITIONS.
    1. The following definitions apply to this regulation:
      1. Absorption area: that area determined by multiplying the length and width of the bottom area of the disposal trench.
      2. Absorption system: any part of a wastewater treatment and disposal system that discharges wastewater by design onto or into the ground.
      3. Absorption trench: excavations less than or equal to three (3) feet in width where the distribution system is laid for the purpose of distributing pretreated waste effluent into the ground.
      4. Adequate secondary treatment: secondary treatment that is similar to or better than the treatment provided by a drainfield meeting all requirements of Section 10(B) and (C).  Absorption beds qualify when minimum separations are met and there is not enough room for a drainfield.  Seepage pits qualify when minimum separation are met and there is not enough room for a drainfield or absorption bed.  If a replacement system will not meet minimum separations, the Department can require elevated or alternative treatment systems.  Adequate secondary treatment in the floodplain is an elevated sand mound or a system that incorporates advanced secondary treatment.
      5. Advanced secondary treatment:  a system designed to lower BOD and TSS to 7 day averages of 40mg/L & 45 mg/L or 30 day averages of 25mg/L & 30mg/L respectively, and when necessary, also lower fecal coliform levels in wastewater effluent. 
      6. Alternative system: a wastewater treatment and disposal system approved by the Department to be used in lieu of a conventional system.
      7. Approved site evaluator: a person approved by the Department to conduct site evaluations.
      8. Bedrock: Material that cannot be readily excavated by hand tools, or material that does not allow water to pass through or that has insufficient quantities of fines to provide for the adequate treatment and disposal of wastewater.
      9. Bedroom: any room that is or may be used for sleeping.  An unfinished basement is considered an additional bedroom. SEE APPENDIX “F”.
      10. Camping: the temporary placement of tents or cabins, or the parking of trailers or vehicles for the purpose of sleeping.  A travel trailer or RV that has skirting installed or has been connected to either
        electrical or sewage services in a permanent manner is not considered camping.
      11. Certified installers: installers of wastewater treatment and disposal systems who have passed an annual examination to ensure sufficient knowledge of the sewer regula­tion.
      12. Cesspool: a seepage pit without a septic tank to pre-treat the wastewater.
      13. Community wastewater treatment and disposal system: a public wastewater treatment and disposal system which serves a non-transient population characterized by residential development.
      14. Construction Season: March 1st through November 30th.
      15. Containment Vault:  a tank that is limited to containing accidental spills.  A tank that receives
        wastewater from a fixture is not a containment vault.
      16. Contaminate: an increase in the concentration of chemicals, viruses, or bacteria in water to a degree which is likely to affect present or future beneficial uses of the water or which violates any applicable ground water or surface water standard.
      17. Conventional secondary treatment: treatment after a septic tank that consists of a drainfield, and includes systems that use infiltration chambers, gravity distribution, or pressure distribution.
      18. DEQ: The Montana Department of Environmental Quality.

      22. Dosing Tank: a water‑tight receptacle placed after the septic tank or other treatment device approved by the Department, equipped with an automatic siphon or pump designed to discharge effluent.
      23. Drain rock: the rock or coarse aggregate used in an absorption system. Drain rock does not include gravels of shale, sandstone, or limestone.
      24. Drainageway: a course or channel along which stormwater moves in draining an area.
      25. Dwelling or residence: one or more structures or portion thereof, which is intended, designed, or used for human occupancy and provides independent living facilities including provisions for sleeping, cooking, and sanitation.
      26. Enlargement (of structure): an increase in the volume, or cubic feet, of a structure.
      27. Equal Distribution:  uniform distribution of septic effluent throughout an absorption system.  Gravity systems with no more than ten (10) foot difference in lateral length or pressure distribution systems meet the definition of equal distribution for the purposes of this regulation.
      28. Escarpment: any slope greater than 50 percent which extends vertically six (6) feet or more as

Prior to the issuance of a temporary repair permit, the owner of the property must execute any contracts, petitions, or agreements required by the utility, the Department, or other entity for the creation of SIDs or RSIDs and must meet other conditions which the municipality, the Department, or utility may require.  The homeowner shall sign a document indicating that he or she will connect to public sewer within 180 days after the installation of the sewer mains designed to service the property.
      4. A temporary repair or increased use permit satisfies the requirements of Section 16, which establishes requirements for replacement systems.
      5. Applicants for temporary permits may instead apply for a normal replacement permit, using the established fees and requirements of the Department.
      6. The granting of a temporary permit for repair or increased use does not guarantee a life expectancy or operation of the system and if the system fails prior to availability of public sewer, further repairs or upgrades to the system may be required by the Department.
  7. INSTALLER CERTIFICATION.
    1. General.
      1. Installation, modification, replacement, or repair of a wastewater treatment and disposal system that requires a permit in accordance with Section 6 must be supervised by a person who has passed an examination administered by the Department to ensure they have sufficient knowledge and training to complete the work in compliance with this regulation.

      3. When revoking a certification, the Department shall provide the installer with a written explanation of the reasons for the revocation in the form of a Notice of Violation.
  8. INSPECTION & FINAL APPROVAL.
    1. All systems must receive final approval from the Department for a permit to remain valid.
    2. Wastewater treatment and disposal systems require an inspection prior to covering the system unless specific permission has been granted by the Department to backfill a portion of the system for a justified reason.
    3. When there is no certified installer on site during an inspection the Department may charge a reinspection fee to return and reinspect the system when a certified installer is on site.  The Department may waive the requirement to have a certified installer on site during an inspection by arrangements made prior to the inspection. 
    4. When final approval is withheld, a written notice of deficiencies and required corrective action must be given to the certified installer or property owner.  The certified installer or property owner must notify the Department upon correction of all deficiencies.  The Department shall confirm the deficiencies have been corrected prior to granting final approval.  If reinspection is required the Department shall charge a re-inspection fee established by the Board.

    8. When a signed copy of the ‘as built’ plans for an engineered system is required by DEQ 4, Appendix D, the owner or authorized agent must submit the plans as described in DEQ 4 to the Department within 90 business days following the final inspection.
    9. Acceptance of a permit by the applicant confers upon the Department the authority to access the installation site at reasonable times to inspect or to collect samples.  The Department may also inspect existing systems that have been subject to complaint(s), create health hazard(s), or have become public nuisances.
    10. Deviations from the approved plans, which do not violate the regulation, may be approved by the Department. Approved deviations must be noted on the inspection form.
  9. SITE EVALUATIONS.
    1. A site evaluation must be conducted by an approved site evaluator who has passed an examination administered by the Department to demonstrate knowledge of soils and site characteristics and how they relate to the design and function of wastewater treatment and disposal systems. The following persons may be approved site evaluators.

      1. All systems must be located and designed in accordance with DEQ 4 unless a more specific or stringent requirement is included in this Code.
      2. Applicants proposing a new wastewater treatment and disposal system, or increased use of a system must designate a full sized separate replacement area that meets all the criteria for the initial drainfield or absorption system without any sizing reductions.
      3. The Department may require that both the primary and replacement drainfield areas be identified by staking prior to construction.
      4. All individual wastewater systems and designated replacement areas being reviewed as part of a Sanitation in Subdivision application must be located on the same lot as the dwelling or business served. This provision does not apply to:
        1. wastewater systems or replacement areas proposed on lots created on or before December 31, 2009; or,
        2. wastewater systems or replacement areas proposed on lots created as part of any Sanitation in Subdivision application submitted to the Department by December 31, 2009; or,
        3. wastewater systems or replacement areas proposed on lots created as part of any subdivisions with preliminary plat approvals from the County Commissioners or City Council by December 31, 2009; or,
        4. wastewater systems and replacement areas located off of the lot prior to application for subdivision.
      5. A structure, movable or immovable, may not be located over, or moved onto, any part of the system.  Vehicles may not be driven over the system after installation, except those portions properly designed to accept traffic loads.  The drainfield or other absorption system must be located and protected in a manner that prevents vehicles from passing over or parking on top of the system.  This area must be kept free of all obstructions, including pavement, which will prevent air from penetrating the soil.
      6. Fill may not be used to overcome minimum vertical or horizontal separation distances in Sections 10(B) and (C), except for sealed components.
    2. Prohibited locations.
      1. Steep slopes.
        1. No system or any portion of a system may be located on a slope that exceeds 35%. 
        2. Systems may not be located on slopes between 15% and 35% unless a registered professional engineer or a person qualified to evaluate and identify soil in accordance with the Natural Resource Conservation Service standards submits adequate evidence that conditions are such that there will be no visible outflow of effluent down slope from the installation of the system.
        3. Systems must meet minimum setback distances from steep slopes in accordance with Table 2.
      2. Floodplain or flood-prone areas. 
        1. Absorption systems may not be located within 100 feet of a floodplain or flood-prone area.
        2. When property within the designated FEMA floodplain can be shown to be above base floodplain elevation, an official action from FEMA is required to remove the area from the floodplain before a permit may be issued by the Department.  If the property is within shaded Zone X floodplain, written approval from the Floodplain Administrator is sufficient.
        3. A parcel containing Zone A approximate floodplain must have the base flood elevation determined by a licensed professional engineer through hydrologic and hydraulic analysis, or another method approved by the Floodplain Administrator before the Department may:
          1. approve a subdivision or,
          2. issue a septic permit on a DEQ-reviewed parcel that was created after August 15, 1983.
      3. Waterways.  A subsurface treatment and disposal system may not be located within a drainage way or within a natural or manmade intermittent watercourse.
      4. Groundwater.  Groundwater depth at any time of less than six (6) feet from the natural ground surface precludes the use of conventional subsurface wastewater treatment and disposal systems. There must be a minimum separation of at least four (4) feet of natural soil between the bottom of the drainfield and the maximum high groundwater elevation.
        1. The Department may require one (1) year of groundwater monitoring conducted by the Department to delineate the highest groundwater level.
        2. If the groundwater is within ten (10) feet of the ground surface, or if there is any reason to believe that the groundwater will be within ten 10 feet of the natural ground surface during any time of the year, groundwater monitoring is required.
        3. The applicant must provide groundwater test holes and piping to a depth of at least nine (9) feet within the   boundary of the proposed drainfield to determine the high groundwater during its peak occurrence. If shallow groundwater or an impervious layer is encountered during excavation of the test holes at a depth less             than nine (9) feet, the piping may be placed at that depth.
        4. The Department may refuse to accept seasonal high groundwater data when total precipitation for the previous year (defined as May 1 of the previous year through April 30 of the current year), or April 1 snowpack water equivalent, measured at the nearest officially recognized monitoring station, is more than 20 percent below the historical average
        5. The Department may consider soil morphology data and data from nearby groundwater monitoring sites with similar soil, geology and proximity to streams or irrigation ditches, if available, to determine maximum groundwater elevation.  Morphology data may only be substituted if groundwater monitoring was conducted and precipitation or snowpack for the monitoring period is more than 20 percent below the historical average per Section 10(B)(3)(d). The Department may charge a fee to be determined by the Board for review of morphology data.
      5. Bedrock and impervious layers. Four (4) feet of natural soil must be present between the bottom of the absorption system and bedrock or an impervious layer throughout the proposed drainfield site and replacement area.
    3. Minimum horizontal setbacks. Minimum horizontal setbacks are shown in Table 2, with clarifying statements shown in 1-8 below.
      1. Sewer lines and sewer mains may be located in roadways and on steep slopes if the lines and mains are safeguarded against damage.
      2. The minimum horizontal setback from a slope or escarpment applies to the slope down gradient of the absorption system.
      3. Sealed transport lines may be located within the flood prone/floodplain area.
      4. If the floodplain has not been designated and its level relative to a wastewater system is in question, the applicant must submit evidence adequate to establish the location of the floodplain.
      5. Sealed components of a wastewater system located in a 100-year floodplain or area of high groundwater must be designed and constructed to prevent surface and ground water inundation.  Pump lines must be pressure tested prior to use and must have a pressure rating of at least two (2) times the operating pressure or pump shutoff pressure, whichever is greater. Pipes must be tested at 1.5 times the operating pressure or pump shutoff pressure, whichever is greater, or must be tested as specified by the manufacturer.
      6. Separation of Water and Sewer.
        1. Horizontal separation of at least ten (10) feet is required between sewer and water mains, unless the sewer main must cross the water line.  The distance shall be measured from the closest edge of each pipe.
        2. Sewer mains which must cross water mains shall be laid to provide a minimum distance of 18 inches between the outside of the pipes. Service lines shall be constructed in accordance with the Uniform Plumbing Code.
      7. The Department may require greater horizontal separation distances than those specified in Table 2 if it determines that site conditions or water quality non-degradation requirements indicate a need for the greater distance.
      8. Exceptions for Irrigation Ditches.
        1. The setback distance from an irrigation ditch to an absorption system may be reduced to a minimum of 50 feet provided the ditch is sealed prior to construction of the system to prevent seepage of water out of the ditch and seepage of wastewater into the ditch.  The setback distances may be reduced to a minimum of 10 feet based on a case by case evaluation of engineered plans for piping submitted to the department.
        2. If the top of the absorption system is to be placed at an elevation equal to or lower than the flow line of the ditch to prevent wastewater effluent from entering the ditch and groundwater monitoring during the peak season demonstrates that seepage of water from the ditch will not result in a depth to groundwater of less than six (6) feet in the area of the absorption system, the setback distance may be reduced to a minimum of 50 feet.
    4. Maximum land application rates.
      1. Wastewater application into the soil may not exceed 700 gallons/useable acre/day for any system or group of systems.
        1. Total area for the purpose of calculating the maximum land application rate may include lots, interior parks, and public right of ways within the subdivision, minus floodplain or flood-prone area.
        2. All parcels included within a proposed project may be considered to determine compliance with this section.
        3. For the purpose of calculating application rate limits each individual single family dwelling unit is considered to have a discharge of 350 gallons per day.  The application rate for multi-family units will be calculated using the flows shown in Table 4.
        4. Flow rates for industrial and non-residential establishments must be as determined by design in accordance with DEQ 4, Chapter 3.
      2. Exceptions:
        1. Existing lots not being reviewed for subdivision to be used for single family dwelling(s) or multi- family dwellings with 4 or fewer dwelling units do not have to meet the requirements of 10(D)(1), but must demonstrate adequate room for both a drainfield and full replacement area and meet all other requirements of these regulations.
        2. If a Level II wastewater treatment system is used and nitrate is projected to be 5 mg/l or less at the end of the mixing zone, wastewater application may increase to 1,400 gallons/useable acres/day.
        3. If a DEQ groundwater discharge permit restricts and requires monitoring of the nitrate level in the effluent, wastewater application may increase based on the following formula: (50 mg/l ÷ x mg/l) x 700 gallons/useable acre/day, where x is the discharge permit nitrate limit in mg/l
  11. PRIMARY TREATMENT REQUIREMENTS
    1. All new and replacement wastewater treatment and disposal systems must provide a primary treatment device prior to disposal in an absorption system.
    2. The primary treatment device must consist of a septic tank that conforms to the design and construction requirements in DEQ 4.

  20. SPECIAL MANAGEMENT AREAS.
    1. Missoula Wastewater Treatment Plant Service Area (MWTPSA). The purpose of the MWTPSA requirements are to place landowners on notice that permission to use wastewater disposal in this area is temporary and is intended to be replaced with discharge to a public sewage treatment plant.  The following restrictions apply to all land within the Missoula Wastewater Treatment Plant Service Area depicted on the map in Appendix D:
      1. The Department may not issue a permit for an increased use, a new wastewater treatment and disposal system, or a replacement seepage pit in the MWTPSA unless the owner(s) execute a deed restriction waiving the right to protest the creation of a Special Improvement District (SID) or a Rural Special Improvement District (RSID) for the installation of public sewer, using the language set forth below. The filing of a deed restriction is not required if previously filed for the same parcel, or where similar language has been shown on an approved and filed subdivision plat or certificate of survey.
      2. Owners of property encumbered by a deed restriction must connect to sewer as established in the deed restriction.
      3. A new division of land, including any subdivision as defined in Section 4 within the MWTPSA must exhibit language consistent with Section 20(A)(1) of this regulation on the face of the recorded plat or on a Certificate of Survey.  Language approved by the City and County Attorney is available at the Department.
      4. Any person installing a new or replacement septic tank in an area of the MWTPSA designated for STEP (shown in Appendix D) must install a STEP septic tank with manway.
      5. A Multi-user or community wastewater treatment and disposal system serving five or more connections in the MWTPSA must be designed and located to allow a single, common future connection point to public sewer, and must conform to the design criteria established by the City of Missoula Public Works Department. The design, installation and inspection of all mains, service lines to public sewer, STEP tanks, and related appurtenances must be approved by the City of Missoula Public Works Department in accordance with its design criteria for sewers.  As-built plans for all multi-user, community, or dry laid systems must be submitted to the City of Missoula Public Works Department and the Department by the applicant within 90 days of installation.
      6. A new subdivision within the MWTPSA must provide easements as necessary to facilitate the connection of all parcels requiring facilities to public sewer service when sewer mains become available.
      7. If a property in the MWTPSA is part of a proposed subdivision containing five (5) or more lots of less than two (2) acres per lot in all phases, the developer must provide a multi-user or community wastewater treatment and disposal system converging at one common point that may be easily connected to public sewer when sewer mains are available to service the property. 
      8. A properly designed, installed and inspected dry laid pressure or gravity main connecting the lots with appropriate easements may be used in place of a multi-user or community system as required above in areas where the subdivision contains no more than fourteen 14 lots in all phases approved after September 21st, 1994 when the City Engineer makes the following written findings provided to the Department:
        1. That the design of the dry-laid system meets City Public Works criteria for design of sewers; and,
        2. that a dry laid main is preferable in a given instance to a community or multi-family septic system for eventual connection to public sewer because:
          1. the dry laid system will be less expensive for future homeowners to connect to public sewer; or
          2. because site characteristics make it infeasible to connect a community or multi family system to public sewer in the future.
      9. When the subdivision includes perpetually dedicated common areas and wildlands or an area reserved from development by deed restriction until public sewer becomes available, the Department will divide the area of such dedicated land by the number of lots and add the result to each lot area to determine applicability of Section 20(A)(7). 
    2. Rattlesnake Valley Special Management Area.  The following restrictions apply to wastewater treatment and disposal systems in the portion of the Rattlesnake Creek Drainage above the Mountain Water intake dam classified as A-closed by DEQ (see Appendix E).

      1. All parcels with existing plat approvals may install systems if the site meets the four (4) foot separation required from the bottom of the disposal trench to high seasonal groundwater.  High groundwater testing may be required to satisfy this requirement.
      2. All parcels without existing plat approvals may only install one single family system if all other requirements of this regulation are met.
      3. The Department shall perform a preliminary inspection of the site with the excavator at the start of construction to ensure that:
        1. maximum depth is maintained; and
        2. the absorption system is located properly.
      4. Wells must be grouted to a minimum twenty (20) feet.  Bacterial samples are recommended and disinfection may be necessary to ensure a potable water supply.  A copy of the well log shall be submitted to the Department showing adequate compliance with the plat approval and Montana DNRC Well Drilling Requirements. 
      5. The Department may not approve further subdivisions which create lots that generate wastewater or require wastewater facilities in the area until the cause of water contamination is discovered and the problem corrected.

“I/We, the undersigned, hereby certify that I/we are the owners of the real property located at (legal description) which is in an area where public sewer is planned to be installed.  I/we hereby waive any right to protest an RSIDs or SIDs affecting said property for the purpose of financing the design and construction of a public sewer benefiting said property.  Further, my/our signatures on this waver may be used in lieu of my/our signature(s) on an RSID or SID petition for the creation of one or more RSID or SID petitions for the purpose of financing the design and construction of a public sewer benefiting the above-described property.  This deed restriction is granted by the current and future owners of the property to the County or City of Missoula in exchange for permission to discharge sewage into the ground until such time that public sewer is installed.   This deed restriction shall also constitute an agreement whereby the owner(s) must connect to public sewer within 180 days after public sewer mains are installed and available to the property.

      accessed by the system’s users for maintenance and repair of the system.

20. SPECIAL MANAGEMENT AREAS.

(A) Missoula Wastewater Treatment Plant Service Area (MWTPSA). The purpose of the MWTPSA requirements are to place landowners on notice that permission to use wastewater disposal in this area is temporary and is intended to be replaced with discharge to a public sewage treatment plant.  The following restrictions apply to all land within the Missoula Wastewater Treatment Plant Service Area depicted on the map in Appendix D:

      (1) The Department may not issue a permit for an increased use, a new wastewater treatment and disposal system, or a replacement seepage pit in the MWTPSA unless the owner(s) execute a deed restriction waiving the right to protest the creation of a Special Improvement District (SID) or a Rural Special Improvement District (RSID) for the installation of public sewer, using the language set forth below.

“I/We, the undersigned, hereby certify that I/we are the owners of the real property located at (legal description) which is in an area where public sewer is planned to be installed.  I/we hereby waive any right to protest an RSIDs or SIDs affecting said property for the purpose of financing the design and construction of a public sewer benefiting said property.  Further, my/our signatures on this waver may be used in lieu of my/our signature(s) on an RSID or SID petition for the creation of one or more RSID or SID petitions for the purpose of financing the design and construction of a public sewer benefiting the above-described property.  This deed restriction is granted by the current and future owners of the property to the County or City of Missoula in exchange for permission to discharge sewage into the ground until such time that public sewer is installed.  

This deed restriction shall also constitute an agreement whereby the owner(s) must connect to public sewer within 180 days after public sewer mains are installed and available to the property.

This waiver runs with the land and shall be binding on the transferees, successors, and assigns of the owners of the land described herein.

All documents of conveyance must refer to and incorporate this waiver.”

                    The filing of a deed restriction is not required if previously filed for the same parcel, or where similar language has                                been shown on an approved and filed subdivision plat or certificate of survey.

              (2) Owners of property encumbered by a deed restriction must connect to sewer as established in the deed restriction.

(3) A new division of land, including any subdivision as defined in Section 4 within the MWTPSA must exhibit language consistent with Section 20(A)(1) of this regulation on the face of the recorded plat or on a Certificate of Survey.  Language approved by the City and County Attorney is available at the Department.

(4) Any person installing a new or replacement septic tank in an area of the MWTPSA designated for STEP (shown in Appendix D) must install a STEP septic tank with manway.

(5) A Multi-user or community wastewater treatment and disposal system serving five or more connections in the MWTPSA must be designed and located to allow a single, common future connection point to public sewer, and must conform to the design criteria established by the City of Missoula Public Works Department. The design, installation and inspection of all mains, service lines to public sewer, STEP tanks, and related appurtenances must be approved by the City of Missoula Public Works Department in accordance with its design criteria for sewers.  As-built plans for all multi-user, community, or dry laid systems must be submitted to the City of Missoula Public Works Department and the Department by the applicant within 90 days of installation.

(6) A new subdivisionwithin the MWTPSA must provide easements as necessary to facilitate the connection of all parcels requiring facilities to public sewer service when sewer mains become available.

(7) If a property in the MWTPSA is part of a proposed subdivision containing five (5) or more lots of less than two (2) acres per lot in all phases, the developer must provide a multi-user or community wastewater treatment and disposal system converging at one common point that may be easily connected to public sewer when sewer mains are available to service the property. 

(8) A properly designed, installed and inspected dry laid pressure or gravity main connecting the lots with appropriate easements may be used in place of a multi-user or community system as required above in areas where the subdivision contains no more than fourteen 14 lots in all phases approved after September 21st, 1994 when the City Engineer makes the following written findings provided to the Department:

      (a) That the design of the dry-laid system meets City Public Works criteria for design of sewers; and,

      (b) that a dry laid main is preferable in a given instance to a community or multi-family septic system for eventual connection to public sewer because:

            (i)  the dry laid system will be less expensive for future homeowners to connect to public sewer; or

      (ii) because site characteristics make it infeasible to connect a community or multi family system to public sewer in the future.

(9) When the subdivision includes perpetually dedicated common areas and wildlands or an area reserved from development by deed restriction until public sewer becomes available, the Department will divide the area of such dedicated land by the number of lots and add the result to each lot area to determine applicability of Section 20(A)(7). 

(B) Rattlesnake Valley Special Management Area.  The following restrictions apply to wastewater treatment and disposal systems in the portion of the Rattlesnake Creek Drainage above the Mountain Water intake dam classified as A-closed by DEQ (see Appendix E). 

      (1) A wastewater treatment and disposal system serving one (1) single family dwelling or other use with flows less

            than or equal to a single family dwelling per lot or parcel will be allowed provided all other requirements are met.

      (2) Except for a boundary line relocation, the Department may not issue a permit or approve a Certificate of

            Subdivision Approval for subsurface disposal of wastewater for a new division or subdivision of land inside

            the special management area.

      (3)The Department may place any conditions on a wastewater treatment and disposal system permit it deems

            necessary to ensure compliance with the A-closed classification standards, including but not limited to requiring

            an alternative treatment system effective at removing pathogens.

(C) Roman Creek/Touchette Lane Special-Management Area.  The following restrictions shall apply to all land included within the E 1/2 of Section 29, W 1/2 of Section 27, Section 28, T15N, R21W, bordered on the north by the Frenchtown Irrigation Canal and bordered on the south by U.S. Interstate 90.

(1) All parcels with existing plat approvals

(3) The Department shall perform a preliminary inspection of the site with the excavator at the start of construction to ensure that:

(a) maximum depth is maintained; and

(b) the absorption system is located properly.

(4) Wells must be grouted to a minimum twenty (20) feet.  Bacterial samples are recommended and disinfection may be necessary to ensure a potable water supply.  A copy of the well log shall be submitted to the Department showing adequate compliance with the plat approval and Montana DNRC Well Drilling Requirements.    

(5) The Department may not approve further subdivisions which create lots that generate wastewater or require wastewater facilities in the area until the cause of water contamination is discovered and the problem corrected.

(D) Seeley Lake Special Management Area. The following restrictions apply to land located in the NW quarter of T16  

       R15 Section 2, the East half of T16 R15 S03, and the South half of T17 R15 S35 (see Appendix G).

      (1) New or increased use may not be approved unless the Department determines that it will not cause or contribute

            to a violation of the nitrate standard established in 76-5-605, MCA.

      (2) The Department will evaluate septic permit applications on a case by case basis, using the best information

            available including, but not limited to, nitrate sample results and existing studies on groundwater flow direction.

            The Department may require an applicant to supply additional information to substantiate that groundwater will be

            protected.

      (3) Provided there has been no unapproved increased use, replacement systems will be allowed in this area.

(E) Non-designated Areas of Concern.

              The Department may impose restrictions or conditions on new, increased use or replacement wastewater treatment

              and disposal permits in areas where the activities may cause or contribute to the violation of water quality

              standards established in Title 75, Chapter 5, MCA.

  1. Purpose. The purpose of this regulation is to protect the public health, safety and welfare of the people and animals of Missoula County and to control and prevent the spread of rabies.
  2. Authority. Sections 50-2-116(1)(f) and (g), MCA, require local boards of health to identify, assess, prevent and ameliorate conditions of public health importance and to protect the public from the introduction of and spread of communicable disease. Section 50-2-115(2), MCA, authorizes local boards of health to adopt regulations that do not conflict with regulations adopted by the Department of Public Health and Human Services for the control of communicable disease. Rabies or rabies exposure is identified as a reportable communicable disease pursuant to ARM 37.11.203.
  3. Incorporation by Reference. In adopting this regulation, the Board finds that the rabies prevention and management recommendations set forth in the National Association of State Public Health Veterinarians, Inc., “2011 Compendium of Animal Rabies Prevention and Control” and in an official report of the American Public Health Association entitled “Control of Communicable Diseases Manual” provide an accepted scientific basis for regulations to prevent the spread of rabies.

    (1) Missoula County, the Owner of every dog, cat, or ferret 3 months of age or older shall have the animal vaccinated before the animal is 4 months old and thereafter in accordance with the Compendium. An animal receiving its initial vaccination is not considered effectively vaccinated for 28 days.
    (2) Unvaccinated dogs, cats, or ferrets more than 3 months of age that are acquired or moved into Missoula County must be vaccinated within 30 days of purchase or arrival unless there is documented evidence of current vaccination.
    (3) The Owner is responsible for assuring that his or her dog, cat, or ferret wears a collar or harness with identification and a durable tag indicating a current rabies vaccination and the valid year(s) of the vaccination securely attached. Dogs will be deemed to be in compliance with this requirement if they are wearing a current license tag issued by the Department.
    (B) Revaccination: The Owner of every dog, cat, or ferret shall have the animal revaccinated prior to the end of the12th month after initial vaccination. Thereafter, the interval between revaccinations should conform to the recommendations contained in the Compendium except that for dogs, only those vaccines that are approved for a tri-annual booster shall be given.
    (C) Vaccination Exemption: If, after an animal receives one initial and one booster rabies vaccination, a licensed veterinarian determines that an additional vaccination would endanger the animal’s life due to disease or other medical considerations, the animal may be exempted from the requirement for revaccination while the condition exists. The licensed veterinarian must complete and submit to the Department an Exemption From Rabies Vaccination document on a form approved by the Department. After receipt of such form, the Department shall issue a Rabies Vaccination Exemption Certificate, copies of which shall be provided to the veterinarian and the Owner of the exempted animal. If an exempted animal bites another animal or person and the Department seeks to determine the immune status of the biting exempted animal, immune status testing must be provided at the expense of the Owner. If an exempted animal bites it must be revaccinated after the quarantine period is over.
    (D) The safety and efficacy of rabies vaccination for wildlife and hybrids have not been established and no rabies vaccinations are licensed for these animals. Hybrids and wildlife animals will be treated as unvaccinated animals.
  7. Vaccination for Rabies Prior to Transfer of Animal Ownership.
    (A) It is unlawful for any person to sell, adopt out, or give away any dog, cat, ferret over 3 months of age unless, such animal has been vaccinated against rabies by a licensed veterinarian.

As an alternative to vaccination at the time of sale, adoption or gift of the animal, licensed veterinarian clinics, the Animal Control Shelter, Animal Shelters and Animal Welfare Organizations may sell a rabies certificate to the person acquiring the unvaccinated animal for presentation to a licensed veterinarian. The licensed veterinarian may redeem the rabies certificate for costs of administration of the vaccination from the shelter issuing the certificate. The issuer of the rabies certificate must verify that the animal has been vaccinated within 30 days of sale, adoption or gift, and promptly notify Animal Control if the vaccination has not been verified.

    (C) As soon as possible after investigating a report of possible rabies exposure, the local health officer must inform the exposed person or the individual responsible for the exposed person if that person is a minor whether or not treatment is recommended to prevent rabies and provide a referral to a health care provider.
    (D) Whenever the circumstances involve a dog, cat, or ferret, the local health officer must either:
    (1) Authorize impoundment of the animal for observation for signs of illness during a ten-day quarantine period at an Animal Shelter, veterinary facility, or other adequate facility approved by the Department, and ensure that any illness in the animal during the confinement or before release is evaluated by a veterinarian for signs suggestive of rabies; or
    (2) If the symptoms observed are consistent with rabies, order the animal euthanized and the head sent to the Department of Livestock’s diagnostic laboratory at Bozeman for rabies analysis. The local health officer may also order an animal euthanized subsequent to isolation, and the brain analyzed.
    (E) After the quarantine period is over, the animal must be vaccinated prior to release.
    (F) If a biting animal dies during the quarantine period for any reason whatsoever, the Animal Control Officer shall have the head of the animal sent to a diagnostics laboratory for rabies testing.
    (G) If a biting animal has a current rabies vaccination, the Local Health Officer may permit the Owner to confine the animal at home in strict Quarantine for 10 days, subject to a determination by the Local Health Officer that that the Owner is cooperative, responsible, has the facilities to confine the animal in Quarantine isolation and will permit observation of the confined animal by the Department upon request. Permission for home confinement may be revoked by the Local Health Officer at any time during the confinement period.
    (H) Any dog, cat or ferret who has salivary contact with or is bitten or scratched by a bat or other wild mammal known to be a potential rabies virus carrier, will be regarded as having been exposed to rabies unless determined otherwise by diagnostic testing of the biting animal.
    (1) If exposed to a rabid animal, unvaccinated dogs, cats or ferrets must be immediately destroyed. If the Owner is unwilling to have such animal destroyed, the unvaccinated animal must be placed in strict quarantine for six (6) months, at the Owner’s expense, in a secure place designated by the Local Health Officer and vaccinated before release.
    (2) If exposed to a rabid animal, a vaccinated dog, cat or ferret shall be immediately revaccinated, leashed and/or confined to the Owner’s property for ninety (90) days.

    (D) Animals impounded under this regulation shall be released to the Owner at the end of the quarantine period, as determined by the Local Health Officer. The Owner shall be required to pay any impoundment costs, including veterinarian evaluation or treatment and vaccination, prior to release of the animal. If an impounded animal is not claimed by its Owner and fees and costs paid, within 96 hours of the end of the quarantine or investigation period, the Owner forfeits all right, title and interest thereto to Missoula County and the animal is subject to adoption in accordance with Missoula City-County Animal Control Ordinance.
