Answers from the rulebook for Pacific Junction

Rules another office applies inside Pacific Junction

Pacific Junction does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

  • Who permits septicMixed (with conditions)

    Private sewage disposal systems (septic) on land inside Pacific Junction city limits: the state rule applies and is administered by the local county board of health (Mills County) or the Iowa DNR as administrative authority

    • The administrative authority is the department or the local county board of health, as the rule defines it.
    • Pacific Junction city has not been shown to adopt its own septic ordinance; none was found.
    • Chapter 69 header states a rescission date of 7/12/31 under Iowa Code section 17A.7.
    ““administrative authority” means the department or the local county board of health as authorized by iowa code section 455b.172 and chapter 137.”
  • Septic permitRequired

    New or altered private sewage disposal systems on land inside Pacific Junction city limits

    • Applies to a system installed or altered as described in 567—69.1(3)“b”.
    • Permit is issued by the administrative authority (Iowa DNR or the local county board of health) before construction.
    • Repairs that do not change treatment or disposal are not alterations, but the discharge restrictions in 69.1(8) still apply.
    • Connection to a public sewer (potw) is required where one is available, so the septic permit question arises only where no potw is available.
    “69.1(4) construction permit required. no psds shall be installed or altered as described in 69.1(3) “b” unless a construction permit issued by the administrative authority is obtained prior to construction.”
  • Septic inspectionRequired

    Newly constructed private sewage disposal systems on land inside Pacific Junction city limits

    • Inspection is conducted by the administrative authority (Iowa DNR or the local county board of health).
    • A final as-built drawing is kept on file with the construction permit.
    • The system must also be entered into the department's onsite wastewater tracking system after final inspection.
    “c. final inspections. the administrative authority shall conduct an at-location inspection of all newly constructed psdss before the system is backfilled. a final as-built drawing shall be made as part of the final inspection and kept on file with the construction permit.”
  • Mandatory utility hookupConditional

    New homes inside Pacific Junction city limits: a septic system may not be used where a publicly owned treatment works (potw) sewer is available, so connection to public sewer applies when available

    • Availability is determined by the administrative authority.
    • A potw may be considered unavailable when it is more than 200 feet from any proposed building or exterior drainage facility on a lot that abuts and is served by a potw.
    • When a potw becomes available within 200 feet, any building then served by a septic system must be connected to the potw within a time and under conditions set by the administrative authority.
    • Whether Pacific Junction operates a public sewer and whether a city ordinance requires connection were not found in any official source.

    potw availability distance: <= 200 feet (Final determination of availability is made by the administrative authority.)

    “(1) no psds shall be installed, repaired, or rehabilitated where a publicly owned treatment works (potw) is available or where a local ordinance requires connection to a potw.”

Unanswered questions are usually a sign that Pacific Junction publishes no rule on the point, not that none exists. Mills County’s page lists the county offices to call.
