Dear Mr. Bender:

In your letter of January 17, 1974, you asked about corrosion control requirements for steel risers on plastic service lines.

Steel risers on plastic services must be coated and cathodically protected as required by Section 192.455 of Subpart I of the Federal regulations. So as to facilitate cathodic protection, each service riser must be electrically insulated from other house piping such as at the regulatory shutoff valve or meter as required by Section 192.467(b). The level of protection must meet one or more of the criteria contained in Section 192.463.

Also, the frequency for monitoring the cathodic protection applied to service risers is covered by Section 192.465.

We trust this clarifies the requirements for corrosion control measures applicable to steel risers on plastic services. If you desire any further information, please advise.

Sincerely,

/signed/

Joseph C. Caldwell
