Answers from the rulebook for Lidderdale

Rules another office applies inside Lidderdale

Lidderdale 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 Lidderdale city, Iowa. The state rule is set by the Iowa DNR; the local county board of health is the administrative authority that issues permits and inspects, and applies inside Lidderdale city as well as in the rest of the county.

    • The rules in 567 IAC chapter 69 are applicable only to private sewage disposal systems (psdss).
    • The statewide rule defines the administrative authority as the DNR department or the local county board of health.
    • I did not verify which county board of health serves Lidderdale city on an official Carroll County page; the official Carroll County, Iowa health office page could not be opened.
    ““administrative authority” means the department or the local county board of health as authorized by iowa code section 455b.172 and chapter 137.”

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