Dear Ms. Felix:

This is in response to your November 08, 2012 email requesting clarification of the requirements for application of the "L" decal on non-DOT specification glass fiber reinforced plastic (GFRP) DOT-407 and 412 equivalent special permit tankers under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180).  Specifically you ask if an "L" marking should be applied to non-DOT specification GFRP DOT-407 and 412 equivalent tankers operating under special permit.

Your email does not reference any specific special permits.  However, the lining inspection requirements of § 180.407(f) do not apply if cargo tanks are authorized by the special permit they are operating under to be manufactured and utilized in transportation without a liner. 

Test and inspection marking requirements for cargo tanks are provided in § 180.415.  Section 180.415(a) requires each cargo tank successfully completing the test and inspection requirements contained in § 180.407 to be marked as specified in the rest of that section; to include an "L" marking for lining inspections.  If no liner is present in a cargo tank operating under a special permit, no lining inspection is required and no marking in accordance with § 180.415 is required. 

Unless otherwise provided for by special permit, any cargo tank utilizing a liner is subject to the lining inspection requirements of § 180.407(f) and subsequently the marking requirements in § 180.415(b).   

I hope this information is helpful.  If you have further questions, please do not hesitate to contact this office.

Sincerely,

Delmer Billings
