BE IT ORDAINED BY THE COUNCIL OF THE CITY OF WATERLOO, IOWA, as follows: That Article V, For Thermoplastic Use for Natural Gas, is hereby added to Ordinance No. 2021 , known as the Gas Piping Code, as follows: FOR THERMOPLASTIC USE FOR NATURAL GAS ARTICLE V Section 500 - Pipe Code for Thermoplastic Underground Only The requirements for plastic pipe or tubing for natural gas pipe for underground use shall be governed by this Code for such installation. Plastic pipe or tubing of the following types are approved for outdoor underground fuel lines and are limited to 100 psig maximum pressure Thermoplastic Pipe PE 3408 Type III Grade 3 Class C. Section 501 - Plastic Pipe Plastic pipe or tubing of the following types are approved as pipe for pressures up to 100 psig. Wall thickness and operating temperatures affect these. Buried pipe will be less than 73 degrees Fahrenheit normally while plastic in a riser is limited to the 120 degrees Fahrenheit rating.

Plastic tubing will become more flexible than normal in 100 degree temperature. Care shall be taken to prevent stretching. Plastic tubing will become more rigid than normal in freezing temperatures. The tubing will not become brittle or fracture at temperatures well below zero. Care shall be taken to prevent sharp bends which may kink the tubing. The minimum radius of 25 pipe diameters shall be used. See table below for recommended minimum bend radius.

The above-ground part of the plastic line is protected against deterioration and external damage by manufactured riser or Schield Pipe. 2. The plastic line is not used to support external loads. 3 . Riser support bracket be used to support each riser. 4. All buried fuel lines will have a valve at the beginning for control of gas in the buried portion of the line as per drawing. 5. For leak surveying purposes and general safety, plastic pipe will not be allowed under buildings, decks, etc. TYPICAL HOUSE TO GARAGE FUEL LINNZ HOUSE GARAGE , Value �� -i�sulatcd Union1! - ' Anadeless Riser . ... ..

When installing pipe through bores, it may be desirable to occasionally use rigid sticks of plastic pipe rather than coils. This may be particularly true in cold weather conditions. When using coiled plastic pipe, care should be taken to inspect for out-of-roundness. Fusions ( sidewall or butt) should not be made to out-of-round sections. Section 503 - Plastic Pipe--Qualifying Persons to Make Joints No person may make a plastic pipe joint unless that person has been qualified under the applicable joining procedure by: 1. Appropriate training or experience in the use of the procedure; and 2. Making a specimen joint from pipe sections joined according to the procedure that passes the inspection and test set forth in the following paragraph. BOOK 2.82 PAGE 2U7 Ordinance No. 3579 Page 3 The specimen joint must be: 1. Visually examined during and after assembly or joining and found to have the same appearance as a joint or photographs of a joint that is acceptable under the procedure; and 2. In the case of a heat fusion: (i) Tested under any one of the test methods listed under state code applicable to the type of joint and material being tested; ( ii) examined by ultrasonic inspection and found not to contain flaws that would cause failure; or (iii) cut into at least 3 longitudinal straps, each of which is: (A) Visually examined and found not to contain voids or discontinuities on the cut surfaces of the joint area; and (B) Deformed by bending, torque or impact, and if failure occurs, it must not initiate in the joint area. (C) A person must be requalified under an applicable procedure, if during any 12-month period that person: ( 1) does not make any joints under that procedure; or ( 2) has 3 joints or 3 percent of the joints made, whichever is greater, under that procedure that are found unacceptable by testing under U.S. Department of Transportation. (D) Each operator shall establish a method to determine that each person making joints in a plastic pipeline in his system is qualified in accordance with this section. Section 504 - Inspection of Joints No person may carry out the inspection of joints in plastic pipes required by U.S. Department of Transportation code unless that person has been qualified by appropriate training or experience in evaluating the acceptability of plastic pipe joints made under the applicable joining procedure. Section 505 - Installation of Plastic Pipe Plastic pipe must be installed below ground level. Plastic pipe must be installed so as to minimize sheer or tensile stresses. Plastic pipe must have an electrically conductive wire #12 copper THW or equal or other means of locating the pipe while it is underground. Section 506 - Pipelines Each segment of a plastic pipeline must be tested in accordance with this section. The test procedure must insure discovery of all potentially hazardous leaks in the segment being tested. The test pressure must be at least 150 percent of the maximum operating pressure of 50 psig, whichever is greater. However, the maximum test pressure may not be more than three times the design pressure of the pipe. The temperature of thermoplastic material must not be more than 100 degrees Fahrenheit during the test. ma 282 PAGE 268 Ordinance No. 3579 Page 4 Section 507 - Testing While Installing Air pressure must be maintained at all times when pipe is being buried. It will be inspected by a City of Waterloo Inspector.
