1. A. The permittee shall use replacement pipe that meets the following minimum requirements:

   1. 1. The replacement pipe shall be High Density Polyethylene (HDPE) Pipe manufactured from a high density, high molecular weight polyethylene resin which conforms to ASTM D-1248 and meets the requirements for Type III, Class A, Grade P34, Category 5, and has a PPI rating of PE 3408, when compounded.

      1. a. The pipe produced from this resin shall have a minimum cell classification of 345434D or E (inner wall shall be light in color) under ASTM D3350.
   2. 2. The pipe shall be made from virgin material. No reworked material shall be used except that obtained from the manufacturer's production of the same formulation.
2. B. Before commencement of work, the permittee shall submit to the department for approval, the vendor's technical data, which shall include details about the physical properties of the pipe and pipe dimensions.

3. C. The Standard Dimension Ratio (SDR) classification for various depths shall be as follows.

   1. 1. The permittee shall specify the SDR for the various depths listed in Table I.
   2. 2. The depth shall be measured from the upstream and downstream manhole rim to the invert (the lowest point inside the pipe, where fluid begins to flow) of the existing sewer in the pipe segment to be replaced.

4. 3. The SDR shall be selected for the deeper of the two manholes for a given pipe segment
