Highway 12 &Luce Line Trail, Orono, Hennepin County, Minnesota, Plan No. PLB 1106-00212
We are NOT able to grant approval at this time of the plans and specifications submitted for the above-
designated project. The following comment(s) outline the changes and/or additional information that must be
submitted so that we can further evaluate the plans and specifications for compliance with the standards of this
department:
1. Sheet C4.1 appears to indicate utility easement lines around the watermain, forcemain sewer, and lift
station within the property lines. Please indicate whether these utilities are located within a permanent
easement where all utilities within the easement are permanently owned and maintained by the city of
Orono. If so,please provide documentation from the city of Orono stating this is correct. If the utilities
within the easement lines will not be permanently owned and maintained by the city,they are subject to the
Minnesota Plumbing Code. The following information is then required:
a. The plans indicate polyethylene pipe for the watermain and the forcemain sewer, but do not indicate the
construction standard of the pipe. The plan must be revised to include the pipe construction standards,
joining method, and the installation standard to be used for directional boring.
b. If the pipe materials are not listed as approved materials in the Minnesota Plumbing Code for the
intended purpose, alternate material approval must be obtained from the city of Orono before the plans
will be approved by this office. The project owner must make a written request to the city for the
alternate materials and installation method. The pipe construction standards and installation standard
must be clearly identified in the request. The owner must acknowledge that the materials and
installation method are not approved in the Minnesota Plumbing Code.
c. If the city of Orono approves the alternate materials and installation method, a copy of the local
approval must be submitted to this office.
2. Using Minnesota Rules, part 4715.2310:
a. The 4-inch building drain branch must be at least 5 inches in size at the branch connection serving the
bathroom in Room No. 140 on Sheet P 1.
