§ 50.06. Permit requirements.

(a)

Permit required. No person shall install, alter, repair or extend any individual sewage treatment system in the city without first obtaining a permit from the building official for the specific work and complying with the provisions of Chapter 33 of this Code. Permits shall not be required for inspections involving the review and maintenance of systems. A building permit or variance may not be issued for the addition of a bedroom on a property served by a system unless the system is in compliance with the applicable requirements, as evidenced by a certificate of compliance issued by a licensed inspector, site evaluator or designer. However, the requirements may be waived between November first and April thirtieth of each year provided that an inspection of the system is performed no later than the following June first and the applicant submits a certificate of compliance no later than the following September thirtieth.

(b)

Application contents. Permit application shall be made in writing upon forms provided by the building official and shall contain data including, but not limited to that required under Minnesota Rules, Chapter 7080, and the following:

(1)

Correct legal description of the property on which the proposed work is to take place.

(2)

Site plan, drawn to scale, showing the location of all proposed and existing structures in relation to the boundary lines of the property; present or proposed location of water supply facilities and water supply piping; the name of the individual or firm who will install the sewage treatment system; terrain features such as bluff lines, waterways and water bodies; buried utilities; easements and other unique features of the site.

A scale drawing showing the following shall be kept on file at the department of saftey and inspections:

a.

Lot dimensions;

b.

House location;

c.

Location and plan of the proposed individual sewage treatment system;

d.

Relative elevations, in Saint Paul datum, of the house, lot corners and soil treatment area;

e.

Location and elevations of percolation test holes and soil borings;

f.

Slope of ground at site of soil treatment area; and

g.

Distance to all surface waters, wells, proposed wells, springs or other surface water within one hundred fifty (150) feet of the proposed soil treatment area.

h.

Soil test data, including soil boring logs, percolation test data with field notes, and location and identification of the test area.

i.

Plans and details of the proposed installation or work, including engineering data when required and supporting data attesting to compliance with the minimum standards of this chapter.

j.

Building plans showing existing and proposed room arrangement and uses.

k.

For other establishments, calculated or measured water use rates, occupancy and occupant load.

l.

Evidence of compliance with state or other jurisdiction regulations where applicable.

(3)

The following supporting data, which shall be kept on file at the department of safety and inspections:

a.

Log of all soil exploration work, including a description of the various strata encountered;

b.

Groundwater conditions, including indications of seasonal groundwater fluctuations, such as mottling, and the presence of gray soil coloration as indicated by a soil color with a chroma of two (2) or less (Munsell Color);

c.

Design data for the system;

d.

Soil test data derived from soil borings and percolation tests for each proposed site or installation shall be in accordance with Minnesota Rules 7080.0110. At a minimum, four (4) satisfactory soil borings per site shall be made. Borings shall be made by auger or excavation and shall be staked and protected until notification that field evaluation has been completed. If one (1) or more borings encounters unsuitable or limiting conditions, additional borings shall be made in order to outline an adequate area of suitable soil conditions;

e.

Results of at least two (2) soil percolation tests per site performed according to Minnesota Rules 7080.0110, subpart 4 and including:

1.

Within the outlined area, a minimum of two (2) percolation tests, evenly spaced, shall be made. Where soil conditions vary within the tested area, one (1) additional percolation test shall be made in each soil type. Fill soils may require more than one (1) additional percolation test;

2.

Percolation rates shall be determined for each test hole and recorded on worksheets showing all measurements and calculations.

f.

Written verification from the installer that the system was installed as designed and indicated on the "as built" drawings and in compliance with all the requirements of Minn. Rules Chapter 7080, and this chapter, as from time to time amended.

g.

Prior to final acceptance, a certificate of compliance and an "as built" drawing of the system must be submitted to the department of safety and inspections.

(4)

No building permit shall be issued for the construction, alteration, expansion or remodeling of any dwelling or other establishment served by an individual sewage treatment system until the permit required for the treatment system has been issued. Occupancy shall be prohibited until a final inspection of the system has been conducted.

(c)

Site evaluation. An evaluation of the site's suitability for an individual sewage treatment system according to the evaluation factors provided in Minnesota Rules 7080.0110, shall be made by an individual or firm licensed by the MPCA as a site evaluator.
