Internally lined USTs without corrosion
protection. An owner and permittee of an internally lined UST that does not
have corrosion protection must have the UST internally inspected or assessed in
accordance with a method that has been evaluated and approved by a third party
to ensure the tank is structurally sound and the lining is still performing in
accordance with all original design specifications. An owner and permittee must
have the internal lining inspections or assessments conducted:
(a) Within ten years after lining;
(b) Every five years
Internally lined USTs with corrosion protection. An owner and permittee of an
internally lined UST that has corrosion protection must conduct internal lining
inspections or assessments of the UST as required by section (1) of this rule.
However, internal inspections are not required if the owner and permittee meet
each of the following conditions:
integrity of the UST was inspected or assessed before the addition of corrosion
documentation of the inspection results and the internal inspection or
assessment is provided to the department that demonstrates the work was
conducted in accordance with a code of practice developed by a nationally
recognized association, an independent testing laboratory or by a method that
has been third party evaluated and approved: and
(c) If the original integrity inspection or
assessment was not conducted, documentation is not available or the
documentation is not sufficient as determined by the department, an owner and
permittee must complete at least one internal inspection of the tank lining
using the method specified byAmerican Petroleum Institute Publication
1631, "Recommended Practice for the Interior Lining of Existing Steel
Underground Storage Tanks".
(3) The owner and permittee must permanently
decommission an UST system if any internal inspection determines that the UST
is no longer structurally sound.
