Passed and adopted by the City Council of the City of Chanhassen, this 26th day of January , 1987. ATTEST: 42QJJb City Clerk/Manager Yes No Absent Hamilton Horn Johnson Boyt Geving None None .' e e e ( (, October, 1986 EXHIBIT A PROPOSED CHANGES FOR MINNESOTA RULES CHAPTER 7080 Adopted by ISTS Advisory Committee Note: Numbers in parenthesis refer to 6 MCAR 4.8040 The following changes have been proposed by the ISTS Advisory Committee for purpo~es of accuracy, improving clarity, and because of recent technical advances. These changes will be recommended as proposed by the ISTS Advisory Committee to the Minnesota Pollution Control Agency Board. The proposed changes will not officially be part of Minnesota Chapter 7080 until after being presented at public hearings throughout Minnesota and being adopted by the MPCA Board of Directors. The proposed change for 7080.0020, Subp. 17, page 5691 (B.16. on page 4) is: Subp. 17. ~~~~ ~~~&% Drainfield ~ Clean rock, crushed igneous rock'or similar insoluble, durable and decay-resistant material ~ ~ ~ ~ ~ ~ percent ~ wei~ht of dust, sand, silt, or clay. The size shall range from three-fourths inch to two and one-half inches. Reason: The trench rock of three-fourths inch size or greater cannot possibly perform any filtration function on septic tank effluent. The fact that trench rock is called "filter material" has lead to many misunderstandings and misconceptions by sanitary engineers who are familiar with the operation of a trickling filter. The primary purpose of the trench rock is to distribute effluent over the soil surface. It simply does not perform any filtration function. The words "filter material" appear numerous times in Chapter 7080 and all of the references to filter material will also need to be changed. The words "free from" mean that absolutey no material can be in the trench rock. Thus, if someone rigorously applied this definition, practically all of the rock presently available could be declared improper. The amount of 0.1 percent by weight provides a quantity by which the rock can be judged and is approximately equivalent to about 1/25 inch of depth of this material over the bottom vf the trench. This small amount should provide little restriction to flow. The proposed change for 7080.0020, Subp. 29, page 5692 (B.28 on page 5) is: Subp. 29. Sand. A soil texture composed by weight of at least S5 ~~6eR~ ~, S~~. p.*~~g~Qa ~aR~~R~ ~R ~~~e ~Weeft ~~~~ ufl6 ~~~ ~ ~ percent Qf ~ coarse. coarse. ~ medium ~ varyin~ in ~ ~ ~ ~ ~ ~ ~ ~ ..iQ. pt:>rcent Qf .fine. Q..t: ~ .fine. ~ ranaina in ~ between ~ ~ .o-..a.s. ~ ~ ~ ~ ~ lQ percent Qf particles smaller ~ ~ mm. Reason: It is important that the sand layer which is referred to in mound construction have no more than 10 percent of particles smaller than 0.05 mm. The proposed specification for sand is essentially that which is suggested by the Small Scale Waste ManagemA!1t: D!"r..,.;ACjoo ':1 'i7i.sr:...l!''1'''~ ..r"',...,.... -",..,'":',~..,~- " ~e~O?~~~ ~~~ ~C~~ ~~-~~~-~.,; e e e { ( . ~ -2- Also, for the proper performance of sewage treatment mounds and liner systems it is critical that the amount of silt or clay, and fine sand and very fine sand be limited. Since research has shown that soils having more than 50% of very fine sand and fine sand will have a slower long term acceptance rate than would be indicated by their percolation rate, the amount of fine sand and very fine sand permitted in this definition should be reduced. The proposed change for 7080.0020, Subp. 41, page 5692 (B.40. on page 6) is: Delete the entire definition Subp. 41.

Note: The remaining definitions will be renumbered. Reason: This definition can be deleted since mounds will be considered standard systems under the proposed changes. (" The proposed. change for 7080.0020, Subp. 45, page 5693 (B.44. on page 6) is: Subp. 45. Standard system. An individual sewage treatment system employing a building sewer, sewage tank, and~A soil treatment system ~~ry ~~~w~ a~ seepaqe bed or trenehe~7 drafn~fe~d, e-r ~~~-:t~~ consisting .Q.f trenches. seepaQ'e ~ gJ: mound Reason: One of the proposed changes is to move the section on mounds from 7080.0180 (Appendix A) to 7080.0170 (Section H) entitled "Final Treatment and Disposal." Thus, mounds will become one of the referred to "standard" systems. The proposed change for 7080.0040, page 5694 (C.l.b.(4) on page 8) is: Add Subp. 4. ~,i. An individual sewaae trpatment system ~ .u permitted ~ A ~ ~ .Q.f Q'overnment ~ ~ inspect.ed gJ: certified accordinQ' ~ ~ standards ~ ~ ~ ~ .Q.f Q'overnmp-nt gJ: ~ authorized reprp-sentativp-. Reason: It has been recommended by several inspectors that there is no. provision in Chapter 7080 requiring that local units of government inspect the construction of individual sewage treatment systems. This section is to provide a statement concerning the requirement for such inspection. The proposed change for 7080.0100, Subp. 4, page 5695 (C.3.d. on page 9) is: d. The following agencies and associations shall each have one non-voting ex officio member to assist the Advisory Committee and to be a.vised, in turn, on matters relating to ISTS: the Agency, the DNR, Department of Health, the U.S.D.A. Soil Conservation Service, the Metropolitan Council, the Association of Minnesota Counties, the Minnesota Association of ~ Offretats7 To~nships, the League of Minnesota Cities, and the Minnesota Society of Prnfess~.~~~l ~:l~i~.~c-~ --- e . . . If 'l ,T 'l -3- Reason: The Minnesota Association of Township Officials changed their name to the Minnesota Association of Townships. The proposed change for 7080.0100, Subp. 5, page 5695 (C.3.e. on page 9) is: e. All members shall be appointed by the Agency Board from recommendations by the affected groups. All members shall serve for ~~ ~ years, with terms staggered so as to maintain continuity. Reason: The Advisory Committee has not followed the term of office as specified, a rigorous application of the two year term would mean that we would need to meet once each year to select one-half of the members. Also, two years is not long enough for an individual to become acquainted with the various aspects of Chapter 7080 and possible changes to that document. Should members not be able to serve for a four year term, Subp. 5 has a provision for filling a vacancy. The proposed change for 7080.0130, Subp. 2.F., page 5698 (F.2.a. (6) on page 13) is: (6) Baffles ~ ~ inte~rally ~ ~ ~ ~ affixed ~ A perma'nent waterproof adhesive .QJ;, affixed ~ stainless ~ connectors. ~ ~ bottom. Sanitary tees, which ~ used ~ baffles, shall be affixed to the inlet and outlet pipes with a permanent waterproof adhesive.

The proposed change is for purposes of clarity since it was argued that the previous wording did not describe sanitary tees as being baffles, which they are. The proposed change for 7080.0130, Subp. 2.M. (l),page 5698 (F.2.a. (13) (a) on Page 14) is: (a) There shall be one or more manholes, at least 20 inches least dimension, and located within 6 feet of all walls of the tank. The manhole shall extend through the cover to a point within 12 inches ~ ~ ~ ~~ ~ lS'%x rr-rene:t oe:ow finished grade.

In the interest of safety, there should be an additional cover at the bottom of the manhole which can be removed by special equipment. Thus, this cover needs to have some minimum weight to prevent the curious from opening it. See the attached sketch for details. , , , . . . .., .. i . ~ " . Top Manhole - Cover ( t . '.
