Septic compliance inspections in Pine County, MN

A compliance inspection is a full evaluation of a septic system by an MPCA-licensed inspector, reported on MPCA's form. It ends in either a certificate of compliance or a notice of noncompliance. It is different from the septic disclosure a seller gives a buyer, and different from a pump-out receipt.

When Pine County requires one

Pine County has required point-of-sale inspections countywide since its septic ordinance took effect on April 1, 2014. Under the current ordinance, a compliance inspection of an existing system is required when the property is sold or transferred, when a construction permit is needed to repair or upgrade the system, when a change in use could affect the system, when a bedroom addition needs a permit, with any permit or variance application in shoreland, when an operating permit is renewed, and when the county has reason to check, such as a complaint.

Cities and townships that run their own septic programs (Pine City, Rock Creek, Henriette, Arna, Pokegama, and others) set their own requirements. The table in our point-of-sale inspection guide shows who handles what.

What the inspector checks

For an existing system, the county ordinance requires the inspection to assess the watertightness of every treatment tank, the vertical separation between the bottom of the drain field and saturated soil or bedrock, and any sewage backup, surface seepage, or discharge. For a bedroom addition it also checks that the system is big enough for the new total. Under state rules, the tank integrity part must be done on an empty tank unless an assessment from the past three years is available, so plan for a pump-out if there is no recent one.

Reports, timing, and how long a certificate lasts

The inspector has 15 calendar days after the inspection to submit the result to the county, and the county has 15 calendar days to deliver it to the owner. A certificate for an existing system stays valid for three years, and one for a new or replacement system for five, unless evidence of noncompliance turns up. At a sale, a certificate on file from within three years (or five, for a system less than five years old) can be used.

Winter sales, missing inspections, and escrow

For sales between November 15 and April 15, when frozen soil prevents a determination, the county requires a winter agreement with an SSTS permit application and an inspection by the following June 1. If a sale closes without an inspection, a transfer agreement is filed and the results must reach the county within 60 days after the transfer. If the seller cannot provide a certificate, the ordinance calls for an escrow of 150% of an installer's written estimate, or 110% of a signed contract price.

Who can do it

Only an MPCA-licensed inspection business can perform and sign a compliance inspection. Not every pumper holds an inspector license, so check the license type in MPCA's SSTS license search. Rush City and Harris are in Chisago County, which has its own rules; see the Rush City page.

Before the inspector arrives

• Find your permit, as-built drawing, and recent pumping receipts
• Mark or uncover the tank lids, or ask about risers
• Ask whether a pump-out is needed or a recent tank assessment can be used
• Book early, so a repair does not hold up closing
