Sec. 265.444  Inspections.

    (a) During construction or installation, liners and cover systems 
(e.g., membranes, sheets, or coatings) must be inspected for uniformity, 
damage and imperfections (e.g., holes, cracks, thin spots, or foreign 
materials). Immediately after construction or installation, liners must 
be inspected and certified as meeting the requirements of Sec. 265.443 
by a qualified Professional Engineer. This certification must be 
maintained at the facility as part of the facility operating record. 
After installation, liners and covers must be inspected to ensure tight 
seams and joints and the absence of tears, punctures, or blisters.
    (b) While a drip pad is in operation, it must be inspected weekly 
and after storms to detect evidence of any of the following:
    (1) Deterioration, malfunctions or improper operation of run-on and 
run-off control systems;
    (2) The presence of leakage in and proper functioning of leakage 
detection system.
    (3) Deterioration or cracking of the drip pad surface.

    Note: See Sec. 265.443(m) for remedial action required if 
deterioration or leakage is detected.
