310 CMR, § 80.35 - Requirements for Periodic Inspections

(1) Owners and Operators are responsible for ensuring that periodic visual inspections meeting the requirements in 310 CMR 80.35(2) through (4) are conducted at all underground storage tank systems. The Owner, Operator or certified Class A or B operator, or an individual under the direction of the Owner, Operator, or certified Class A or B Operator shall conduct the periodic visual inspections.

(2) Every 30 Day

(a) Inspect leak detection equipment and records as follows:

1. Verifying leak detection equipment is currently on and is operating with no alarms or other unusual operating conditions present;

2. Verify all indications of leakage or releases were responded to in accordance with 310 CMR 80.26 including, but not limited to, printing a report from the electronic system if applicable; and

3. Verify leak detection records are complete, accurate and current.

(b) Inspect each spill bucket and cover as follows:

1. Visually inspect to determine if there is solid or liquid material in the spill buckets, and remove and manage solid and liquid material in accordance with applicable federal, state and local laws and regulations;

2. Visually inspect spill buckets and covers for signs of corrosion, deterioration, cracks and holes and repair and replace as necessary;

3. Verify that sensors are set in accordance with the manufacturer's specifications, if applicable, or, if no such specifications exist, the sensors shall be placed at the lowest possible location in the spill bucket;

4. Check for and remove obstructions in the fill pipes;

5. Check the fill pipe caps to verify they are securely on the fill pipes; and

6. For double-walled spill buckets with interstitial monitoring, check for leakage in the interstitial area.

(c) Verify that grade level fill covers are properly color-coded to correctly reflect the regulated substance in the UST system in accordance with 310 CMR 80.24(4).

(3) Every 90 days inspect each turbine, intermediate and dispenser sump without continuous monitoring sensors, except sumps that only contain a single-walled siphon line with no connections within the sump and sumps that only contain European Suction Systems or sumps that do not contain any regulated substance piping connections, as follows:

(a) Visually inspect sumps, sump covers and manhole covers for damage, corrosion, breakage and wear, leaks to the containment areas and releases to the environment, and repair and replace as necessary;

(b) Remove solid and liquid material from the sumps in accordance with applicable federal, state and local laws and regulations; and

(c) For double-walled sumps, check for leakage in the interstitial area.

(4) Annually

(a) Inspect each turbine, intermediate and dispenser sump with continuous monitoring sensors, except sumps that only contain a single-walled siphon line with no connections within the sump and sumps that only contain European Suction Systems or sumps that do not contain any regulated substance piping connections, as follows:

1. Visually inspect sumps for damage, corrosion, breakage and wear, leaks to the containment areas and releases to the environment, and repair and replace as necessary;

2. Remove solid and liquid material from the sumps in accordance with applicable federal, state and local laws and regulations;

3. Verify that all sumps sensors are operating in accordance with the manufacturer's specifications and are placed in accordance with the manufacturer's specifications, or, if no such specifications exist, the sensors are placed at the lowest possible location in the sump; and

4. For double-walled sumps, with interstitial monitoring check for leakage in the interstitial area.

(b) For hand held release detection equipment, check devices such as tank gauge sticks for operability and serviceability.

(5) If the inspection indicates that any underground storage tank system components are not properly operating or are not being maintained in accordance with 310 CMR 80.00, manufacturer's specifications and applicable codes and standards, the Owner or Operator shall repair said component(s) in accordance with 310 CMR 80.33.

(6) Every requirement under 310 CMR 80.35(2) through (4) shall be recorded on an inspection report or log that contains at a minimum the following information:

(a) A list of each area and UST component inspected;

(b) Whether the UST component is properly operating and being maintained; and

(c) Any repairs conducted on UST components designated as not operating or being maintained in accordance with 310 CMR 80.00, the manufacturer's specifications and all applicable codes and standards.

(7) The results of each inspection shall be recorded and retained in accordance with 310 CMR 80.36.
