(3) Aboveground storage tanks containing No. 5 or No. 6 oil for consumption on the premises where stored.

b. Each operator shall institute inventory control procedures capable of detecting a significant variation of inventory. A significant variation shall be considered a variation in excess of 1.0% of the storage capacity of each individual AST. Reconciliations of inventory measurements shall be conducted monthly. If a significant variation persists for two consecutive reconciliation periods, the operator shall conduct an investigation to determine the cause of the variation and reconcile physical measurements to 60°F at 14.7 pounds per square inch absolute. This investigation shall be completed within five working days of the end of the second reconciliation period. If this investigation does not reveal the cause of the inventory variation, the operator shall notify the board department and the local director or coordinator of emergency services and shall conduct additional testing to determine the cause of the inventory variation. The testing method, schedule, and results of this additional testing shall be submitted to the board department for review. For a refinery, a significant variation of inventory shall be considered a loss in excess of 1.0% by weight of the difference between the refinery's input and output of oil.

c. Inventory records shall be kept of incoming and outgoing volumes of oil from each tank. All tanks shall be gauged no less frequently than once every 14 days and on each day of normal operation. For a refinery, the operator shall calculate the input and output of oil at the refinery on a daily basis. The operator shall reconcile daily inventory records with the inventory measurements conducted monthly.

2. Secondary containment.

a. The operator shall have and maintain secondary containment or another method approved by the board department for each AST. The containment structure must be capable of containing oil and shall be constructed in accordance with 40 CFR Part 112 so that any discharge from the AST will not escape the containment before cleanup occurs. The operator shall have each secondary containment or approved method evaluated and certified to be in compliance with the applicable requirements of 40 CFR Part 112, the Uniform Statewide Building Code and its referenced model codes and standards, and 29 CFR 1910.106. The operator of a facility existing on June 24, 1998, shall have had this evaluation or certification performed by a professional engineer or person approved by the board department on or before June 30, 1998, and every 10 years thereafter, unless otherwise exempted.

b. If the secondary containment cannot be certified to be in compliance with the applicable requirements of 40 CFR Part 112, the Uniform Statewide Building Code and its referenced model codes and standards, and 29 CFR 1910.106, the operator must upgrade, repair, or replace the secondary containment to meet the applicable requirements listed in subdivision 2 a of this subsection unless the board department accepts the certification with qualifications.

c. The operator of a facility shall have the evaluation and certification performed every 10 years by a professional engineer (PE) licensed in the Commonwealth of Virginia or other state having reciprocity with Virginia or by a person approved by the board department unless otherwise exempted.

d. The professional engineer shall not certify the secondary containment until all of the applicable requirements of 40 CFR Part 112, the Uniform Statewide Building Code and its referenced model codes and standards, and 29 CFR 1910.106 have been met. In the event the professional engineer certifies the secondary containment with qualifications, such qualifications will be subject to review and approval by the board department. If the certification contains qualifications that may impact the ability of the secondary containment to contain a discharge of oil as required by subdivision 2 a of this subsection, the deficiencies must be corrected and the secondary containment must be reevaluated and recertified by a professional engineer.

e. At a minimum, the certification statement for the secondary containment must contain the following statement: "Based on my evaluation, I hereby certify that each secondary containment structure for (insert the facility name and tank identification information) is in compliance with the applicable requirements of 40 CFR Part 112, the Uniform Statewide Building Code and its referenced model codes and standards, and 29 CFR 1910.106."

f. The certification must be signed and sealed by a professional engineer licensed in the Commonwealth of Virginia or other state having reciprocity or by a person approved by the board department.

g. Operators of facilities existing on June 24, 1998, and exempted under § 62.1-44.34:17 D of the Code of Virginia (i.e., exempted facilities not engaged in the resale of oil) shall have had this evaluation completed on or before June 24, 2003, and every 10 years thereafter.

h. Operators of a newly installed AST shall have this evaluation completed prior to being placed into service and every 10 years thereafter.

i. Operators of an existing AST with a current engineering certification statement on November 1, 2015, may maintain their existing engineering certification statement until their next required certification, or 10 years, whichever is sooner. At such time, the certification statements must contain the statement required in 9VAC25-91-130 B 2 e.

3. Safe fill and shutdown procedures.

a. Each operator shall institute safe fill, shutdown, and transfer procedures, or equivalent measures approved by the board department, that will ensure that spills resulting from tank overfills or other product transfer operations do not occur. Written safe fill, shutdown, and transfer procedures shall be maintained by the operator for use by facility personnel.

All receipts of oil shall be authorized by the operator or facility personnel trained by the operator who shall ensure the volume available in the tank is greater than the volume of oil to be transferred to the tank before the transfer operation commences. The operator shall ensure the transfer operation is monitored continually, either by manual or automatic means, until complete. The operator shall ensure that all tank fill valves not in use are secured and that only the tank designated is receiving oil.

b. All oil transfer areas where filling connections are made with vehicles shall be equipped with a spill containment system capable of containing and collecting those spills and overfills. The containment system shall be designed to hold at least the capacity as required by 40 CFR Part 112.

c. If installed, an automatic shutdown system utilized during transfer of oil shall include the capability to direct the flow of oil to another tank capable of receiving the transferred oil or the capability to shut down the pumping or transfer system. This automatic shutdown system shall be tested prior to each receipt of oil and records of testing shall be maintained at the facility.

d. All ASTs shall be equipped with a gauge that is readily visible and indicates the level of oil or quantity of oil in the tank. In addition, the storage capacity, product stored and tank identification number shall be clearly marked on the tank at the location of the gauge. These gauges shall be calibrated annually.

4. Pressure testing of piping. All piping shall be pressure tested as specified in this subsection or using an equivalent method or measure approved by the board department at intervals not to exceed five years. The operator of a facility or AST existing on June 24, 1998, shall have completed the initial test on or before June 30, 1998, except operators of existing facilities or ASTs for which compliance was exempted under § 62.1-44.34:17 D of the Code of Virginia (i.e., exempted facilities not engaged in the resale of oil). These excepted operators shall have completed the initial test on or before June 24, 2003. All newly installed or repaired piping shall be tested before being placed into service.

a. A pressure test may be a hydrostatic test at 150% maximum allowable working pressure (MAWP) or an inert gas test at 110% MAWP.

b. A test conducted and certified by an American Petroleum Institute (API) authorized piping inspector to be in conformity with the API 570 Piping Inspection Code is deemed an equivalent method of testing approved by the board department.

c. The board department may consider on a case-by-case basis requests for approval of other equivalent methods or measures which conform to industry recommended practices, standards and codes. The operator shall submit a request for approval of a proposed equivalent method or measure to the board department as specified in 9VAC25-91-160.

Upon renewal of an approved contingency plan submitted under this subsection, the board department shall consider the individual facilities subject to all provisions of subsections E through J of this section.

E. Oil discharge contingency plans shall be reviewed, updated if necessary and resubmitted to the board department for approval every 60 months from the date of approval unless significant changes occur sooner. Operators shall notify the board department of significant changes and make appropriate amendments to the contingency plan within 30 days of the occurrence. For the purpose of this chapter, a significant change includes the following:

1. A change of operator of the facility;

2. An increase in the maximum storage or handling capacity of the facility that would change the measures to limit the outflow of oil, response strategy or operational plan in the event of the worst case discharge;

3. A decrease in the availability of private personnel or equipment necessary to remove to the maximum extent practicable the worst case discharge and to mitigate or prevent a substantial threat of such a discharge;

4. A change in the type of product dealt in, stored or handled by any facility covered by the plan for which a MSDS or its equivalent has not been submitted as part of the plan; or

5. A change in the method or operation utilized for the early detection of a discharge to groundwater (i.e., change in a method of leak detection).

F. Updated plans or certification for renewal of an existing plan shall be submitted to the board department for review and approval not less than 90 days prior to expiration of approval of the current plan. Submittal of the certification for renewal for an existing plan shall be made in accordance with the provisions of subsection B of this section. All notifications of changes, renewals, submissions and updates of plans required by this chapter shall be directed to the respective regional office.

G. An oil discharge exercise may be required by the board department to demonstrate the facility's ability to implement the contingency plan. The board department will consult with the operator of the facility prior to initiating an exercise. Where appropriate, the board department will ensure coordination with federal agencies prior to initiation of an exercise.

H. The board department may, after notice and opportunity for a conference pursuant to § 2.2-4019 of the Code of Virginia, deny or modify its approval of an oil discharge contingency plan if it determines that:

1. The plan as submitted fails to provide sufficient information for the board department to process, review and evaluate the plan or fails to ensure the applicant can take such steps as are necessary to protect environmentally sensitive areas, to respond to the threat of a discharge, and to contain and clean up an oil discharge within the shortest feasible time;

2. A significant change has occurred in the operation of the facility covered by the plan;

3. The facility's discharge experience or its inability to implement its plan in an oil spill discharge exercise demonstrates a necessity for modification; or

4. There has been a significant change in the best available technology since the plan was approved.

I. The board department, after notice and opportunity for hearing, may revoke its approval of an oil discharge contingency plan if it determines that:

1. Approval was obtained by fraud or misrepresentation;

2. The plan cannot be implemented as approved;

3. A term or condition of approval of this chapter has been violated; or

4. The facility is no longer in operation.

J. A Facility Response Plan (FRP) developed pursuant to § 4202 of the federal Oil Pollution Act of 1990, Pub. L. No. 101-380, 33 USCA § 2716 (1996), may be accepted as meeting the requirements of subdivisions A 1 through A 22 of this section. The operator shall submit a copy of the FRP and a copy of the currently valid FRP approval letter for the facility for review and approval by the board department. The FRP shall contain a cross reference in order to index pages for the specific requirements of the ODCP. The FRP shall also contain the satisfaction of the requirements of subdivisions A 13 a and A 18 of this section. This information shall be resubmitted in accordance with the renewal period established by federal statute or regulation but in no instance shall the renewal period exceed five years. The board department shall be notified of any plan amendments within 30 days of the amendment.

9VAC25-91-180. Groundwater characterization study (GCS).

A. Section 62.1-44.34:15 of the Code of Virginia requires the operator to apply to the board department for approval of an ODCP. The ODCP shall be accompanied by other relevant information required by the board department (e.g., groundwater characterization study (GCS) of each facility with an aggregate aboveground storage capacity of one million gallons or greater of oil). The purpose of this GCS is to determine baseline conditions and flow of groundwater within the geographic boundaries of the facility. The operator's results of the GCS shall be subject to the review and approval of the board department and shall be submitted to the department as part of the Oil Discharge Contingency Plan (ODCP) referenced in Part IV (9VAC25-91-170, Oil Discharge Contingency Plan (ODCP) Requirements) of this chapter. The GCS wells are required by 9VAC25-91-170 A 13 a in the ODCP requirements.

B. Section 62.1-44.34:15.1 of the Code of Virginia requires that the operator of a facility with an aggregate capacity of one million gallons or greater of oil conduct monthly gauging and inspection, monitoring of well headspace, and quarterly sampling and laboratory analysis of all groundwater monitoring wells located at the facility to determine the presence of petroleum or petroleum byproduct contamination.

C. Although GCS monitoring wells may be approved for use as part of a leak detection system, the GCS well monitoring requirement should not be confused with any requirement for leak detection monitoring wells required by 9VAC25-91-170 A 18.

9VAC25-91-210. Response.

Should any observations or data indicate the presence of petroleum hydrocarbons in groundwater, the results shall be immediately reported to the board department and to the local director or coordinator of emergency services appointed pursuant to § 44-146.19 of the Code of Virginia.

9VAC25-91-220. Resources available.
