A-002: INTRODUCTION

These regulations establish requirements for sub-surface sewage disposal. The Nevada County Department of Environmental Health (hereafter, “Department”) is the agency responsible for the application of this Chapter. The California Regional Water Quality Control Boards (the Central Valley Region for the west slope of the Sierra Nevada and the Lahontan Region for the east slope of the Sierra Nevada) are the state agencies responsible for the protection of ground and surface water quality.

While the Department administers these regulations, the Regional Boards retain the authority to issue permits for any discharge of waste that may affect water quality, including discharges from individual systems. The Regional Boards adopt “Basin Plans” to define beneficial uses of water, adopt water quality objectives, and to provide guidelines to protect water quality.

The Basin Plan for the Lahontan Region contains criteria for individual waste disposal systems. Some of these criteria are more stringent than those provided in these regulations. However, provisions of a Memorandum of Understanding (MOU) between the Lahontan Regional Board and the County will allow the Department to grant exceptions to the onsite criteria established by the Lahontan Regional Board. The Lahontan Basin Plan also establishes a maximum density criteria and contains a prohibition area for individual on-site sewage disposal systems in the Truckee River watershed. The Department will not issue permits for new individual on-site sewage disposal systems in conflict with the Lahontan Basin Plan’s density criteria or discharge prohibition areas, except as otherwise provided in the MOU.

A-004: ORGANIZATION OF THESE REGULATIONS

The sewage disposal regulations are divided into two major parts. The first part is the Administrative, consisting of Sections A-002 through A-046, which explains general requirements for using the regulations and obtaining a permit. The second part is the Technical, consisting of Sections T-048 through T-116 that give the specific requirements for designing, installing and using a sewage disposal system. The Definitions of Terms used in the Administrative section of the regulations are located in Section A-046, and are important in understanding these regulations.

A-006: STATEMENT OF PURPOSE

Regulations Goals and Mission:

To restore and maintain the quality of public waters (see Definitions of Terms), and to protect the public health and general welfare of the people of Nevada County.

To provide technical guidance and standards for on-site wastewater treatment and disposal systems.

To facilitate the process of obtaining a sewage disposal permit, installing the sewage system successfully and maintaining it for it’s long term use.

A-008: GENERAL STANDARDS AND REQUIREMENTS

(1) Approved System. An approved disposal system (sewage disposal or public sewer system) is needed for all structures that generate sewage. The following types of sewage disposal systems are approved under these regulations (see Definitions of Terms):

(A) Standard system.

(B) Special Design systems.

(C) Experimental systems.

(D) Other types of systems permitted in the Technical section, including vault privies, holding tanks, waterless toilets, portable toilet, kitchen waste disposal and graywater systems.

(E) Pit privies may only be approved on a case-by-case basis in accordance with the variance process described in Section A-030, for primitive-type campgrounds where the Department has determined that a septic tank and leachfield are not practicable and vault privies would be inaccessible for service. Additional requirements are located in the Technical section.

Descriptions of these types of systems can be found in the Technical section of these regulations.

(2) Sewage Discharge. A person may not discharge sewage onto the ground or into the groundwater or surface water. A system must treat and dispose of sewage in a manner approved by these regulations.

(3) System Connection. A person may connect any structure, or increase the flow to a system, only if that system is designed and approved to accommodate the flow. A septic system permit may be required as per Section A-024.

(4) System Requirements. In order for a system permit to be approved and issued, the property must have a "site approval report" (see Section A-014) and be free of encumbrances (such as easements, deed restrictions, etc.) which would conflict with installing or operating the system. The design, construction, and operation of a new system must meet the requirements of the Technical section of these regulations.

(5) Public Sewer. When a public sewer system is available (as described in Section A-018 (1) (E)), connection to the public sewer system is required, and a system permit will not be issued. In areas where public sewer systems may become available, planning for future connection to the sewer system is encouraged.

(6) Easements. When any portion of a system will be put on a separate property, an easement or covenant protecting against conflicting uses must be recorded on that property. The Department will provide the form for this requirement.

(7) Replacement Area. A minimum 100% replacement area (see Definitions of Terms), must be provided for any proposed system except for system repairs. The replacement area must meet the same site criteria as a system.

(8) Area Restrictions. The system must be sited in a location that does not conflict with any other applicable county requirements, including, without limitation, those contained in the county General Plan or the county zoning regulations applicable to the property, and erosion control requirements of the Grading ordinance and related regulations. The soils testing and system site must also comply with any applicable restrictions and notes of the recorded map, for example, those designating no-disturbance zones or environmentally-sensitive resources (such as wetlands, landmark groves of hardwood trees or steep slopes) to be avoided.

Unless specifically permitted, a system must remain free from vehicle traffic, driveways, pavement, corrals, arenas, stables, structures, grading, or similar uses or changes. Uses that may damage the system area must be avoided.

(9) Abandoned Wells. Any abandoned well on the property must either be properly destroyed, or maintained for future use, in accordance with the Nevada County Land Use and Development Code, Chapter X (well ordinance), before a sewage disposal system permit can receive final approval and the system is put into use.

(10) Operation & Maintenance. A system must be operated and maintained so that it does not create a public health hazard, public nuisance (as defined in the California Penal Code) or pollute water. Any special operation and maintenance requirements of a system permit must be followed. See also Section A-026.

(11) System Location. Systems should be located where they will be easily accessible for maintenance and repair. Surface runoff, roof, or other types of drainage must not run onto or into your system.

(12) System Failure. A failing system (see Definitions of Terms) must be immediately repaired, or its use discontinued. The Department may require temporary measures to eliminate a public health hazard.

(13) Discrepancies. If any part of these regulations conflict with other laws or regulations, or is found to be invalid, the other parts of the regulations still remain effective.

(14) Other Standards. If a standard is not specified for a system in this Chapter, the most recently Board of Supervisors-adopted Uniform Plumbing Code standard will be used.

A-010: DEPARTMENT STAFF QUALIFICATION REQUIREMENTS

A careful evaluation and analysis of the site conditions is essential to the successful siting and long-term operation of a system. This includes the recognition of on-site soils types, potential for groundwater problems, and consideration of the local geology. This goal is accomplished through the cooperative interaction of your private consultant and Department staff.

The State Regional Water Quality Control Boards delegate authority to the County to regulate and permit individual and small community systems. These Boards establish minimum criteria that counties must follow, to protect public health and waters, as well as fulfill requirements of the Porter-Cologne Water Quality Act. In order for the County to implement these regulations and fulfill the mandates of the State Regional Water Quality Control Boards, the following program of on-going staff education and training is required:

Any Department personnel participating in the site evaluation process of Section A-014 must be thoroughly educated and trained in the subject of on-site sewage disposal systems, and possess current registration as an environmental health specialist in the State of California.

(1) Minimum education requirements include:

(A) A bachelor’s degree or greater, fulfilling the requirements of the Business and Profession Code for registration as an environmental health specialist in California.

(B) Completion of course work in an earth science class, offered through an accredited institution; or similar course instruction provided through a comprehensive environmental health agency which regulates on-site sewage disposal.

(C) On-going annual education/training in sewage disposal for a total of six (6) Continuing Education Units, provided by an accredited institution, a recognized professional organization (e.g., California Environmental Health Association, American Society of Agricultural Engineers, California On-Site Wastewater Association), or a comprehensive environmental health agency.

(2) Minimum experience requirements include:

(A) One (1) year working as a consultant conducting site evaluations for on-site sewage disposal systems; or

(B) Six months working under the direct supervision of qualified staff in the Department’s Land Use Division, conducting site evaluations for on-site sewage disposal systems.

A-012: HOW TO GET A SEWAGE DISPOSAL SYSTEM PERMIT

  1. Obtain a site approval report (see Section A-014).
  2. Make an application for a sewage disposal system permit (see Section A-016).
  3. Pay the applicable fees.

A site evaluation, a site approval report and a sewage disposal system permit are needed to install, repair, or change a system. This applies whether you are an owner, contractor, company or public agency. A permit will only be issued to an owner or the owner's authorized representative (see Definitions of Terms).

A site evaluation is the procedure where your consultant and the Department staff meet at your property and evaluate the site's ability to dispose of sewage. This is where the initial soils testing is done, (i.e., "soil test pit"). Once the site evaluation is finished, your consultant will prepare and submit to the Department a site evaluation report. The Department will then produce a site approval report, which approves or disapproves a location on the parcel for a sewage disposal system permit application.

The sewage disposal system permit application is the actual process for obtaining the permit to work on your system.

A-014: SITE EVALUATION PROCESS

(1) Review Department Records. In general, all Department parcel files are public information. You are encouraged to review the property file before you make an application for a site evaluation. A site approval report is not required where soils testing was conducted prior to the adoption of this Chapter and the Department finds that the site and prior test results are acceptable.

(2) Obtain A Consultant. It will be necessary for you to obtain a consultant (see Definitions of Terms) to help in making the site evaluation. This person will work with you and the Department, and assist you in making important decisions affecting your parcel. The consultant is the person that performs your percolation tests examines your soil test pit, and prepares the site evaluation report .

(3) Make An Application And Pay The Required Fee

(A) You must then make an application for a site evaluation to the Department and pay the required fee. The Nevada County Board of Supervisors sets the fee.

(B) The application form for this service must be filled out completely by the owner or the owner's authorized representative.

(C) It is important that sufficient information be provided with the application. This must include (see Diagram 1):

(1) An accurate location map. We must be able to find your property.

(2) A legible copy of the Assessor's plat.

(3) Additional information will be helpful. This could include: a copy of the survey map (if available), location of wells, streams, ponds, drainage ways, proposed house site, existing buildings, rock outcrops, easements, proposed driveways, and so forth.

(4) Schedule The Site Evaluation. Your consultant will schedule an appointment with the Department to meet at your property to perform the soil tests. The “soils test pits" are excavations with a backhoe to examine the different soil layers. It is essential that the property boundaries are located and clearly identified.

(5) Conduct The Site Evaluation.

(A) Your consultant, the backhoe and operator, and the Department representative will all meet at the property.

(B) A minimum of two (2) soil test pits (see Definitions of Terms) will be excavated in an area proposed for placing a system. In some cases, more soil test pits will be needed to find a suitable area for the sewage disposal system.

(C) Along with the soil test pits, the overall site will be evaluated by the Department and your consultant for other considerations, such as slope, leaking irrigation ditches, setbacks, road cuts, etc. The Department will complete a field report for each site evaluated. The field report will contain information that defines all areas tested, and comments on the ability to dispose of sewage.

(D) All soil test pits must be protected to prevent people and animals from falling in. There are specific State laws which also regulate this. For greatest safety, the soil test pits should be backfilled upon completion of the evaluation. In any case, all soil test pits must be completely backfilled upon completion of the testing.

(E) Where sufficient information is already available, the Department may waive the requirement for soil test pits.

(6) Concerning Wet Weather Testing. Some lots need soil test pits dug and observed during a specific time of year, due to seasonal changes in the groundwater. A Wet Weather test period is defined by the time of year when high groundwater is most likely to occur.

(A) For Western Nevada County (all land less than 5,000-feet elevation), Wet Weather conditions begin when at least 22-inches of precipitation have fallen commencing July 1 of each year, with at least 5-inches in the last 30 days, in Nevada City. For Eastern Nevada County, Wet Weather conditions occur during the months of March, April, and May. However, these time periods may change depending on the specific conditions in a year, and may be modified by the Department if necessary.

(B) The Department may require that a parcel be tested during the Wet Weather test season before a system site is approved, based on revealing conditions seen in the soil test pit. This requirement may also be set based on historical soils information available for an area.

(C) The process for conducting a Wet Weather test is similar to the process for conducting a site evaluation. Different types of Wet Weather tests may be permitted based on individual conditions.

(7) Have Percolation Tests Performed. Percolation tests are normally required before a site evaluation report can be completed. Percolation tests must be done according to the requirements in the Technical section of these regulations.

(8) Obtain A Site Approval Report. The primary purpose of the site evaluation is to determine whether or not a parcel can accommodate a system. If a suitable site is identified at the site evaluation, this will be confirmed in the Department’s site approval report. It also helps preserve property rights by establishing a probable future sewage disposal site for setback considerations when improvements are proposed for neighboring properties, such as wells, ponds, etc. However, if the site evaluation does not identify a suitable area, the site evaluation and approval reports will not support the issuing of a sewage disposal system permit.

(A) Regardless of the outcome of the site evaluation, the consultant for the site must provide the Department a site evaluation report, including a scaled (1”=50’ minimum) site plan identifying the location and results of all soils testing performed. The soils test results provided must show the minimum information required on forms specified by the Department. For sites where a sewage disposal area is identified, the proposed system area and layout must also be shown. The consultant must submit the site evaluation report as specified in Section T-052 (3), within 60 days of completion of the site evaluation.

(B) A site approval report must be prepared by the Department before a sewage disposal system permit application can be accepted. (Exception: a site approval report is not required where soils testing was conducted prior to the adoption of these regulations and the Department finds that the site and prior test results are acceptable.) The site approval report is not a permit to install a system.

(C) The site approval report will specify the type(s) of system(s), if any, that can be approved for a specific site. It will also note any specific limitations or conditions that may be part of an approval for a system. If an off-site easement is required for a system, this easement must be recorded and a copy of the recording provided to the Department.

(D) A site approval report is transferable and runs with the land.

(E) An area approved for a system in a site approval report will be considered the same as an already installed system, for purposes of determining on-site or off-site setbacks. An owner may revoke a site approval report by written request to the Department.

(F) Future changes in laws governing sewage disposal systems may require a modification to the site approval report.

(G) The site approval report and approval for a sewage disposal area are based upon property conditions at the date of the report. Changes made to the property may render that area unacceptable. Examples of types of changes include: grading, cuts and fills, new buildings, wells, ponds, etc. Owners must take care not to encumber or alter the approved area in a manner that affects the future system.

A-016: SEWAGE DISPOSAL SYSTEM PERMIT APPLICATION PROCESS

(1) Permit Required. A sewage disposal system permit is needed in order for any person to install, replace, repair, abandon, or change a system. This applies whether you are an owner, contractor, company or a public agency. A septic permit is valid for two (2) years from the date it is issued. It may be renewed under procedures described in Section A-020.

(2) Site Approval Report Required. A site approval report must be on file at the Department before a sewage disposal system permit application for a new installation can be submitted. (Exception: A site approval report is not required where soils testing was conducted prior to the adoption of this Chapter and the Department finds that the site and prior test results are acceptable.) In general, all of the Department’s property files are public information, and you are encouraged to review your property’s file before you make an application.

(3) Obtain A Sewage Disposal System Permit Application. The owner or the owner's authorized representative must fill out the application for the permit. The application must be filled out completely. You can obtain a package of information as well as an application for a sewage disposal system permit (hereafter "Permit") at the Department. It contains useful and helpful information to assist you. Read carefully the materials you receive to help you make a complete application.

(4) Apply For The Sewage Disposal System Permit And Pay The Required Fee. Make sure your application is complete, and that a site approval report prepared by the Department is in the Department’s file. (Exception: a site approval report is not required where soils testing was conducted prior to the adoption of this Chapter and the Department finds that the site and prior test results are acceptable.) You must pay a permit fee when you make your application. The permit fee varies with the type of permit, and the Nevada County Board of Supervisors determines that amount. A complete application includes, at a minimum:

(A) A good location map with clear instructions on how to find the property (conditions may have changed since the site evaluation).

(B) Two (2) copies of a site development plan drawn to scale (see Diagram 2). Scale must not be greater than one (1) inch equals fifty (50) feet. An example of a site development plan is available from the Department. The plan must be drawn so that it is clear and readable. Include the following information on your plans:

(C) If it is a special design or experimental system, include the following:

(5) Worker's Compensation Responsibility. When applying for a sewage disposal system permit, be sure that you have completed a Worker's Compensation Declaration or Certificate of Exemption from Worker's Compensation Insurance, in compliance with California State requirements.

(6) Permit To Be Acted Upon. The Department will either issue, conditionally approve, or deny the permit application within twenty (20) working days after receipt of your completed application.

A-018: REASONS YOUR PERMIT MAY BE DELAYED OR DENIED

(1) Every effort is made to ensure that your permit application is reviewed and approved quickly and with a minimum of problems. However, certain situations may result in delays or denial of a permit application, renewal, or transfer. These include:

(A) The application is incomplete or contains incorrect information.

(B) The proposed system would be in conflict with these regulations, or laws or regulations of another agency.

(C) The proposed system is significantly different from what was approved in the site approval report.

(D) The proposed system location has been modified or encumbered.

(E) A public sewer system is available as follows:

(1) For existing parcels, the sewer main is within two hundred (200) feet of any boundary of the property, as measured in a straight line; or

For proposed Parcel Maps or Final Maps, the sewer

connection point is within five hundred (500) feet of any boundary of the property, as measured in a straight line; and

(3) The public sewer connection can be legally and physically achieved.

(2) If your permit is denied for any reason, the Department will notify you in writing. You may appeal a permit denial by following the appeal procedures of Section A-032.

A-020: THE ISSUED PERMIT

Your permit will be issued with certain conditions. These are tailored to your specific parcel conditions and type of system. It is important that the person working on your system has a copy of the approved permit and plans. The conditions on your permit ensure that your system is installed properly. In order to facilitate this:

(1) The system must be installed according to the permit conditions. Specific conditions of operation and maintenance issued for your septic permit will remain in effect for the life of the system, unless otherwise specified in the permit.

(2) The person who works on your system must be a licensed contractor or the owner (see Definitions of Terms).

(3) A copy of your approved permit and plans must be at the job site once the work begins and until the final inspection and approval of the work.

(4) Your permit is valid for two (2) years from the date it is issued. It may be renewed or transferred by following these procedures:

(A) Permit Renewal

(1) Your permit may be renewed for a maximum of two (2) additional years. If your permit has expired; a new application and fee are required.

(2) In order to renew your permit, you must make a written request to the Department.

(3) A permit considered for renewal may require review to ensure that there have not been significant changes in technology or knowledge that affect the design of the system. In some cases, the consultant may be required to review their design.

(4) A renewed permit expires when four (4) years have elapsed from the date the permit was first issued. Any further review requires a new permit application and fee to be paid, consistent with subsection (B).

(B) Re-evaluation of Expired Permits: An expired permit is no longer valid. In order to obtain a new permit, a new fee and application are required. When the Department performs an evaluation of your expired permit, consideration is given to the following:

(1) A recent history of system failures in the area.

(2) The proposed type of system has a history of problems, and/or is no longer approved for use.

(3) The Department was not present for the original soil testing, or there is new information about soils in the area.

A permit issued in this circumstance is considered a new permit.

(C) Permit Transfer: A new owner must make a written request for transfer of the permit upon the change of ownership. Expired permits are non-transferable.

(5) If you propose a change to the septic permit (e.g., adding bedrooms, different type of system, new system location, etc.), an additional review fee and new permit conditions may be required.

(6) At times it may be necessary to revise a system design. Either the consultant or the Department may require this due to changes in technology or new information about a particular type of system. This may require the Department to revise the existing permit requirements and/or conditions.

A-022: GETTING YOUR SYSTEM INSPECTED

Be sure to follow the permit conditions and requirements closely. If the approved permit design requires the consultant to inspect the system, make sure you coordinate the construction inspections with both the consultant and the Department. Clear communication with your system installer and consultant is vital.

(1) Inspections) of the system are required. For special circumstances, an on-site pre-construction meeting may be required. The Department may waive any required inspection with sufficient justification.

(2) The system must be installed as required by these regulations and any permit conditions. Make sure the installer has a copy of the approved permit and plans. Any changes to the permit or plans must first be approved by the Department and the consultant (if any).

(3) A request for an inspection must be made to the Department prior to 7:00 AM on the date the inspection is wanted. The Department has a 24-hour phone inspection line to make this process convenient. Incorrect or incomplete inspection request information may delay your inspection.

(4) The system must be ready for the type of inspection you are requesting. All necessary components must be installed and functioning. If extra inspections are needed, an additional inspection fee will be charged.

(5) An accurate "as-built" or record drawing of the complete installed system must be provided to the inspector at the time of final inspection. The Department will provide an "as-built" drawing form with your permit that can be used to meet this requirement.

(6) Following the inspection, the Department will provide you with a written notice for inspection(s) made of the system. The notice will indicate if any further work or action is required. The system may only be backfilled (covered) with written approval from the Department. For work that is not approved, a correction notice will be provided that specifies the changes to be made as provided in Section A-040.

(7) When a consultant's inspection is required, they must provide the Department with a written certification. The certification must indicate that the system has been installed in accordance with the approved design. This is required before a permit can receive final approval.

(8) Systems must be backfilled within ten (10) days of written approval for backfill from the Department and the consultant (if required), or as specified by the approved design. In any case, the system must be protected from damage caused by weather, earth-moving, or other causes, and must not pose a public health and safety hazard. Adequate erosion control measures must be in place in accordance with applicable requirements of other county regulations.

(9) The Department will issue a Certificate of Satisfactory Completion for the system upon satisfactory completion of the requirements of the permit and these regulations.

A-024: HOW TO MAKE CHANGES OR REPAIRS TO YOUR EXISTING SYSTEM

(1) A Permit Is Required. A system permit is required for you to change, repair, or increase the sewage flow to your existing system. However, a permit is not required for servicing or replacing installed mechanical or electrical parts of the system. This would include such items as: float switches, pumps, electrical box, sanitary tee in the septic tank, etc. (Note: a building permit may be needed for some of this work—check with your local building authority). Replacement or addition of a septic tank or leachfield does require a sewage disposal system permit.

(2) Obtain A Site Evaluation. For certain types of changes or repairs to your system, a site evaluation may be required, as described in Section A-014. For purposes of this Section only, the Department may waive the requirement of a consultant for the site evaluation. Examples of situations that may require a site evaluation include: a failing system, adding a bedroom to your house, and relocating your system.

(3) Make Your Permit Application. The process for applying for this type of permit is similar to the procedure described in Section A-016. A permit will be issued if the regulations requirements can be met, there is an approved site approval report (if applicable), and the proposed system will not create a public health hazard or degrade or pollute the public waters

(4) Special Considerations For System Repairs. A failing system (see Definitions of Terms) creates a public health hazard and/or can pollute water.

(A) (1) A failing system must be immediately repaired, or it’s use immediately discontinued. The Department will require temporary measures to eliminate a public health hazard.

(2) If an immediate repair cannot be accomplished, the Department may allow a delay in making the repair. In this case, a Notice of Violation will be issued as described in Section A-040 (3), and will specify temporary measures required to eliminate the immediate public health hazard or pollution of public waters.

(B) (1) If the site will allow for a standard system, this type of system must be used.

(2) If the site does not meet the requirements for a standard system, the Department may approve a permit for a special design system so long as those requirements can be met.

(3) If the site does not meet the requirements for a standard or special design system, the Department may approve a permit for an experimental system or other repair in order to eliminate a health hazard.

(4) Where no type of system can be approved, the system must be abandoned as described in Section A-028.

(5) Obtain A Certificate Of Satisfactory Completion. The Department will issue a Certificate of Satisfactory Completion for the system upon satisfactory completion of the requirements of the permit and these regulations.

A-026: MONITORING AND MAINTENANCE OF YOUR SYSTEM

(1) With the advent of approval of new and innovative methods to develop on-site sewage disposal systems comes the responsibility and requirements to ensure that these types of systems will function properly. While these systems provide a greater ability to utilize parcels previously designated as “unbuildable”, failure to properly operate, monitor and maintain these types of disposal systems will lead to subsequent failure, resulting in health hazards, water pollution, and financial and legal woes for the property owner.

(2) A program of monitoring, operation and maintenance of systems is specified below. Additional performance criteria will be developed by the Department in alliance with the community to more fully implement the overall program framework described below.

The additional performance criteria will be reviewed by the Sewage Disposal Technical Advisory Group and the California Regional Water Quality Control Board.

(3) This program will be administered by the Department to ensure safe property development and use of these systems. All pressurized-distribution systems, mound systems, and sand filter systems developed subsequent to adoption of these regulations, are required to be monitored, inspected and maintained on an on-going basis for the life of the system. The Department will encourage the owners of property with these types of systems developed prior to these regulations to voluntarily enter into this program.

(4) The program includes, at a minimum:

(A) All systems covered by this Section will be inspected at least once annually.

(B) Property owners obtaining a permit for these systems, or new owners taking legal possession of an existing system, are required to sign and record an Agreement with the property title. The Agreement states that the owner will operate and maintain these systems and comply with all applicable requirements in existence, or as may be lawfully changed from time-to-time as described in sub-section (D) below.

(C) Property owners obtaining a permit for these systems, or new owners taking legal possession of these systems, are required to sign and record an Easement Agreement with the property title. The Easement Agreement permits Department staff or certified persons hired to fulfill the requirements of this Section, to enter upon the property at reasonable times and with prior notification, by procedures approved by the Nevada County Board of Supervisors.

(D) The Department may implement changes in requirements for the monitoring, inspection, and maintenance of these systems for just cause, and upon review by the Sewage Disposal Technical Advisory Group, based on new or revised information, or practical experience.

(E) Annual monitoring, inspection and/or maintenance may only be performed by persons who are currently registered, licensed, or certified by the State of California under the Business and Professions Code, and fulfill the requirements of sub-section (F) that follow. Other professional classifications may be considered by the Department on a case-by-case basis.

(F) All persons performing the monitoring, inspection or maintenance service on these systems must be certified by passing a test administered by the Department, demonstrating knowledge and competency in applicable sewage disposal principals. The certification must be valid and current in order to provide this service.

(G) Department staff may make periodic quality assurance checks to ensure that certified system service providers are adhering to the requirements of the regulations, and policies and procedures established for implementation of the regulations. The Department may suspend or revoke a person’s certification for just cause.

(H) All owners of systems covered by this Section will possess and maintain an annual operating permit issued by the Department. The operating permit may be suspended or revoked for failure to adhere to the requirements of the regulations, policies and procedures established for implementation of the regulations. The Department is authorized to take enforcement action described in Section A-040 to ensure that the system does not create a health hazard or pollution.

(5) Enforcement action may be taken under any applicable Section of these regulations. For purposes of this Section, a system which is not in compliance with this Section may be considered a “failing system”, and corrective actions may be taken by the Department as described in Section A-024 (4).

A-028: HOW TO ABANDON A SYSTEM

(1) When A System Must Be Abandoned. Your system must be abandoned under the following situations:

(A) If you have connected to an approved sewer system.

(B) The system will no longer be used.

(C) If you have received a notice or order from the Department to abandon the system (for reasons such as: the system has failed and cannot be repaired, an illegal system, etc.).

(2) How To Abandon The System.

(A) A permit must be obtained before you abandon a system. The application for abandoning the system must include:

(1) Two (2) copies of a site plan showing where the septic tank and leachfield are located.

(2) A description of how the system will be abandoned.

(B) The septic tank must be pumped by a licensed septic tank pumper (a list of licensed pumpers is available from the Department) to remove the contents. You must provide a receipt to the Department showing that this was done.

(C) The septic tank must be abandoned as follows:

(1) If possible, the septic tank cover will be collapsed, or,

(2) If the septic tank cover cannot be collapsed, the tank will be filled so that there is not a cave-in or other structural hazard, or,

(3) The septic tank may be removed to an approved location, and

(4) The septic tank or excavation hole must be filled with clean earth, sand, gravel, or other material approved by the Department.

(D) The building wastewater plumbing system, if not connected to an approved septic or sewer system, must be permanently capped.

(3) Obtain A Certificate Of Satisfactory Completion. The Department will issue a Certificate of Satisfactory Completion for the system abandonment upon satisfactory completion of the requirements of the permit and these regulations.

A-030: HOW TO OBTAIN A VARIANCE

You can apply for a variance from any requirement of these regulations. However, a variance can only be given to reduce or modify a requirement, not eliminate it entirely. In reviewing a variance, sufficient information must be provided by the applicant so that the Director can make a finding that there will not be a health hazard or pollution created, along with other requirements listed below.

(1) No variance will be granted that constitutes a grant of a special privilege inconsistent with limitations placed upon other properties in the vicinity and zoning district. An application for a variance must show:

(A) Special circumstance(s) exist(s) for the property that create(s) a unique hardship, or that will deprive the owner of privileges enjoyed for other property in the vicinity and zoning district in which such property is located; and

(B) The hardship was not intentionally caused by the action of the applicant; and

(C) Granting the variance would not have any significant adverse environmental effect and would not significantly affect use of adjoining property; and

(D) Reduction of requirements would not present a public health hazard or the pollution or degradation of public waters.

(2) The procedure for applying for a variance is as follows:

(A) Obtain an information packet from the Department. It includes useful and helpful information to assist you. Read carefully the materials you receive to help you make a complete application.

(B) Submit the completed application and any needed supplemental information to the Department. You must pay a review fee at that time. The Nevada County Board of Supervisors sets the fee.

(3) The Director or designated staff will review and investigate the variance applicationand either approve, conditionally approve, or deny it in writing within fifteen (15) working days from the date a completed application was received. For unique, lengthy, or complex variances, the applicant may chose to waive the 15-day time period in writing to the Department. California Environmental Quality Act (CEQA) time frames apply to projects where CEQA review is required for that variance. Variances are reviewed on a case-by-case basis.

(4) After conclusion of the investigation, the Director will prepare a written order of specific findings of fact and reasons for granting or denying your variance.

(5) An applicant or any person interested in the variance may appeal any decision of the Director regarding the variance. See Section A-032 for the appeal procedure.

A-032: HOW TO APPEAL A DECISION MADE BY THE DEPARTMENT

(3) Group Organization. The Sewage Disposal Technical Advisory Group will elect a chairperson. The group will adopt reasonable rules of procedure and conduct subject to the approval of the Board of Supervisors.

A-036: LAND DEVELOPMENT REQUIREMENTS

(1) These standards apply to any proposed land development project, including land divisions, use permits, site plans, etc. It is important to demonstrate that a proposed land development project will be able to dispose of sewage safely. Unless otherwise approved by the Department, the site evaluation process of Section A-014 will be used to demonstrate sewage disposal.

(2) The site evaluation process listed in Section A-014 must be completed and the site evaluation report submitted to the Department concurrently with the project application to the Nevada County Planning Department.

The location of the site evaluation must be in a place on the site where a system could be located so as not to conflict with any other applicable county requirements, including, without limitation, those contained in the county General Plan or the county zoning regulations, for example, site development standards to protect environmentally sensitive resources (such as wetlands, landmark groves of hardwood trees or steep slopes).

(3) Requirements for subdivisions:

(A) This is the minimum number of site evaluation reports that must be submitted at the time of application to the Nevada County Planning Department:

Parcel Size

Percent To Be Tested

Less than 5 acres:

Each proposed parcel

5 up to 9.99 acres:

50% of proposed parcels

10 up to 19.99 acres:

30% of proposed parcels

20 acres or greater:

10% of proposed parcels

All proposed parcels must have a satisfactory site approval report as specified in Section A-014 (8), prior to recordation of the map. This requirement may be waived by the Department for subdivisions creating parcels 40 acres or greater.

(B) The site evaluation locations must be distributed throughout the subdivision so as to be representative of logical building sites in the varying conditions found.

(C) The supplemental map recorded with the final record map must include a Minimum Useable Sewage Disposal Area for each proposed parcel. The site for the Minimum Useable Sewage Disposal Area shall meet all the requirements for a Standard or Special Design system, except that slopes cannot exceed 30%. The site must also meet the setback distances as shown in Table 1 of these regulations.

(E) Where there is an existing system on a proposed parcel in a subdivision, the Department may permit a system evaluation in place of providing a Minimum Useable Sewage Disposal Area. The system evaluation may include an on-site inspection of the system, a site evaluation, and demonstrating a 100% repair area. If the results of the system evaluation are satisfactory, the 100% repair area will be shown on the supplemental map for the final record map, instead of a Minimum Useable Sewage Disposal Area for that parcel.

(F) An experimental system is not permitted for creating parcels, with or without a variance.

(4) Except for Centralized Systems as defined in Chapter L-VI Article 3 of the Nevada County Land Use and Development Code, off-site sewage disposal easements may not be used for creating parcels.

(5) All other land development projects must provide at least one approved site evaluation report, unless otherwise approved by the Department. Depending upon the scope and nature of the project, the Department may require additional soils testing in order to ensure an adequate system.

A-038: CENTRALIZED SEWAGE DISPOSAL SYSTEM REQUIREMENTS

Centralized sewage disposal systems must meet the requirements of the Nevada County Land Use and Development Code Chapter L-VI Article 3.

A-040: ENFORCEMENT AND PENALTIES FOR NON-COMPLIANCE

Most residents of Nevada County strive to meet the necessary requirements to ensure that sewage is disposed in a safe and healthful manner. The Department stresses education and cooperation over enforcement. However, when a violation of these regulations exist or the public health could be threatened, this Section applies.

(1) Violations. It is unlawful to construct, install, replace, alter, repair, enlarge, operate, abandon, or maintain a system, or to increase sewage flows to the system, except in conformance with these regulations. Any person who violates any of the regulations or conditions of a permit or causes or maintains a public health hazard may be charged criminally or be subject to civil abatement action to stop the violation, and may be assessed fines, penalties and/or costs.

(2) Right of Entry. The Health Officer, Code Enforcement Officer and the Department are authorized to enforce the requirements of these regulations. Any of them may enter upon any premises to make inspections and perform tests for the purpose of enforcement of code provisions or these regulations or the abatement of a public health hazard or public nuisance, so long as they do so in compliance with State and Federal law. If consent is not given to a search where necessary, an administrative inspection warrant may be secured upon reasonable cause, allowing the inspection.

(3) Enforcement Actions. When a violation, public health hazard or public nuisance has been verified, a Notice of Violation, Correction Notice, and/or Stop Work Order may be issued. A sewage disposal system permit may also be suspended or revoked and any enforcement action permitted by law may be commenced to cure the violation.

(A) Notice of Violation: The Department may issue a Notice of Violation which directs the cessation or correction of a violation or public health hazard. The notice will direct immediate measures required to eliminate a potential or actual public health hazard or a public nuisance. Any further enforcement action permitted by law may be commenced to cure if there is a failure to comply with the requirements of a Notice of Violation.

(B) Correction Notice: The Department may issue a Correction Notice upon a person responsible for working on a system or operating a system where that work or operation is in violation of these regulations and/or conditions of the sewage disposal system permit or operating permit. The Correction Notice will state the measures that must be taken to correct the violation. Failure to comply with the requirements of a Correction Notice is a violation of these regulations, and is subject to any enforcement action permitted by law.

(C) Stop Work Order: The Department may issue a Stop Work Order for work that is in violation of these regulations, the sewage disposal system permit, or is occurring in an unsafe and dangerous manner. The Stop Work Order will be issued to the person responsible for the work, and will specify the reason for the Stop Work Order. It may also direct corrective measures necessary to abate the violation. Work may only recommence upon written release by the Department. Failure to comply with the requirements of a Stop Work Order is a violation of these regulations, and is subject to any enforcement action permitted by law.

(D) Permit Suspension or Revocation:

(1) When the construction or operation of a system is in violation of these regulations or conditions of the permit, or where a person has misrepresented any material fact in the application for a permit, the Department may suspend or revoke the permit.

(2) The Department will provide the owner a written notice of intent to suspend or revoke a permit. The owner will be given the opportunity to request a hearing before the Department. A written request for a hearing must be received by the Department within ten (10) working days of the Department’s written notice. A failure to request the hearing within the ten (10) working days is deemed a waiver of the right to a hearing.

(3) The Department will schedule a hearing within ten (10) working days from the receipt of a written request for a hearing. The Director of the Department shall conduct the hearing. The decision resulting from the hearing may be appealed in accordance with the appeal procedures of Section A-032.

(4) No work, use or operation may continue on a system where the permit has been suspended or revoked. Work or operation on a system may recommence only upon reinstatement of the permit in writing by the Department. A permit that has been revoked will not be reinstated. Before any work, use or operation will be allowed for a revoked permit, a new permit must be applied for and issued by the Department.

(E) Recordation of Notice of Violation: If a procedure has been otherwise adopted by the County for recordation of Notices of Violation, a Notice of Violation of these regulations may be recorded with the County Recorder’s office following those procedures.

A-042: LIABILITY

Department staff charged with the enforcement of these regulations, when acting within the scope of their public employment, are protected from liability by the immunities available to public employees under the California Tort Claims Act (see California Government Code sections 820, et seq.), including, but not limited to, not being liable for adoption or failure to adopt or enforce an enactment; issuance, denial, suspension, or revocation of a permit, failure to inspect, or negligent inspection of, property; and institution or prosecution of judicial or administrative proceedings.

FOOTNOTES:
  1. The 100-feet setback from a septic tank to a well, surface water or canal, may be reduced to 50-feet if the tank is bedded on a 6” layer of sand or ¾” minus aggregate, and passes a water-tight test.
  2. Setbacks shall be measured from the edge of the 10-year historic high water level (western county) or the 100-year historic high water level (eastern county). For western county, where a flood plain is indicated on a FEMA map, the 100-year setback shall be utilized unless a 10-year flood plain has been delineated by a drainage study or other approved methods. In no event shall a system be placed within a 100-year flood plain or within an area of special flood hazard as defined in the Flood Plain Management Regulations contained in Chapter XII of the Nevada County Land Use and Development Code.
  3. Where the deepest portion of the surface water liquid level is higher in elevation than the highest liquid level in the leachfield, this setback may be reduced to twenty-five (25) feet.
  4. Where the deepest portion of the curtain drain liquid level is higher in elevation than the highest liquid level in the leachfield, this setback may be reduced to ten (10) feet. For septic tanks, this setback may be reduced to ten (10) feet if the tank is bedded on a 6” layer of sand or ¾” minus aggregate, and passes a watertight test.
  5. “ROW”=Right of Way
  6. The height (in feet) of the cut or escarpment as measured from the toe of the cut or escarpment vertically to the projection of the natural ground slope.
  7. The ten (10) feet separation applies where adjacent parcels have been developed with a dwelling and approved water supply as defined in Chapter X, Land Use and Development Code. The 50-feet separation shall be used when adjacent parcels have not been so developed. For subdivisions, disposal fields may be ten (10) feet from interior property lines in private well areas if a well has been drilled on the affected parcel and meets Department standards for an approved domestic water supply. The greater setback shown above shall apply to parcels adjacent to the subdivision.
  8. The Department encourages the placement of septic tanks and other treatment units as close as feasible to the minimum separation from the building foundation in order to minimize possible clogging of the building sewer.
  9. A water line constructed of materials approved for use within a building and sleeved in schedule 40 pipe (or approved equivalent) may cross a leach field so long as the water pipe is installed above the highest liquid level of the leachfield, and the sleeve extends a minimum of ten (10) feet on both sides of the leachfield and is constructed so as to be watertight.
  10. A water line constructed of materials approved for use within a building may be installed crossing a septic tank so long as a minimum of one (1) foot of vertical separation is maintained.
  11. A system may be installed underneath overhead power lines or cross other utilities (e.g., canals) providing all of the following conditions are met:

    (a) written authorization is received from the utility company operating and maintaining the utility affected or for which the easement or restriction was granted;

    (b) the Department determines that the encroachment is necessary and there is no other viable area in which to install the system; and

    (c) all construction modifications required by the Department and the affected utility company(ies) are instituted to carry out the purposes of these regulations. Unless otherwise approved, canal crossings shall be made in conformance with current construction requirements of the Nevada Irrigation District.
