Rule 3750-25-15 | Calculations for reportable quantities of continuous releases.

 

[Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules, and federal statutory provisions referenced in this rule, see paragraph (YY) of rule 3750-1-01 of the Administrative Code titled "Referenced materials."]

(A) Except as provided in paragraph (C) of this rule, a release notification shall not be required under rule 3750-25-25 of the Administrative Code for any release of a hazardous substance that is pursuant to the definitions in paragraph (B) of this rule continuous and stable in quantity and rate.

(B) The following terms are defined terms which apply this paragraph of release notification of continuous releases:

(1) "Continuous" or "continuous release" means a release that occurs without interruption or abatement or that is routine, anticipated, and intermittent and incidental to normal operations or treatment processes.

(2) "Normal range" means all releases (in pounds or kilograms) of a hazardous substance reported or occurring over any twenty-four hour period under normal operating conditions during the preceding year. Only releases that are both continuous and stable in quantity and rate may be included in the normal range.

(3) "Routine" means a release that occurs during normal operating procedures or processes.

(4) "Stable in quantity and rate" means a release that is predictable and regular in amount and rate of emission.

(5) "Statistically significant increase" means a release is an increase in the quantity of the hazardous substances released above the upper bound of the reported normal range of the release.

(C) The owner or operator of the facility or vessel shall establish a sound basis for qualifying the release as a continuous release by one of the following methods:

(1) Using release data, engineering estimates, knowledge of operating procedures, or best professional judgement to establish the continuity and stability of the release.

(2) Reporting the release to the Ohio EPA for a period sufficient to establish the continuity and stability of the release.

When an owner or operator in charge of the facility or vessel believes that a basis has been established to qualify the release for reduced reporting under this section, initial reporting shall be made consistent with paragraph (D) of this rule.

(D) The owner or operator of a facility or vessel shall provide the following notifications for any release qualifying for the reduced reporting under this rule:

(1) Initial telephone notification. Initial notification shall be made by telephone to the Ohio EPA. The person in charge shall identify the notification as an initial continuous release notification report and provide the following information:

(a) The name and location of the facility or vessel.

(b) The name and identity of the hazardous substance being released.

(2) Initial written notification. Initial written notification of a continuous release shall be made to the Ohio EPA and appropriate committee for the geographic area where the releasing facility or vessel is located.

(b) The upper and lower bounds of the normal range of the release (in pounds or kilograms) over the previous year.

(c) The source of the release (e.g., valves, pump seals, storage tank vents, stacks). If the release is from a stack, the stack height (in feet or meters).

(d) The frequency of the release and the fraction of the release from each release source and the specific periods over which it occurs.

(e) A brief statement describing the basis for stating that the release is continuous and stable in quantity and rate.

(f) An estimate of the total annual amount that was released in the previous year (in pounds of kilograms).

(g) The following environmental medium affected by the release:

(c) If there is a change in any information submitted in the initial written notification or the follow-up notification other that the change in the source, composition, or quantity of the release, the owner or operator of the facility or vessel shall provide written notification of the change to Ohio EPA and the appropriate committee for the geographic area where the facility or vessel is located, within thirty days of determining that the information submitted previously is no longer valid. Notification shall include the reason for the change, and the basis for the stating that the release is continuous and stable under the changed conditions.

(5) Notification of statistically significant increase in the release. Notification of statistically significant increase in release shall be made to the Ohio EPA as soon as the owner or operator of the facility or vessel has knowledge of the increase. The release shall be identified as a statistically significant increase in the continuous release. A determination of whether the increase is a "statistically significant increase" shall be made based upon calculations or estimation procedures that will identify releases that exceed the upper bound of the normal range.

(E) Each hazardous substance release shall be evaluated annually to determine if changes have occurred in the information submitted in the initial written notification, the follow-up notification, or in a previous change notification.

(F) In lieu of an initial written report or follow-up report, owners or operators of subject facilities subject to the requirements of Section 313 of the SARA Title III, Emergency Planning and Community Right to Know Act (EPCRA) 1986, and Chapter 3751. of the Revised Code may submit to the Ohio EPA and the appropriate committee for the geographic area where the facility is located, a copy of the Toxic Release Inventory Form submitted under Section 313 of SARA Title III, Emergency Planning and Community Right to Know Act (EPCRA), and Chapter 3751. of the Revised Code the previous July first, provided that the following information is added:

(b) The frequency of the release and the fraction of the release from each release source and the specific periods over which it occurs.

(c) A brief statement describing the basis for stating that the release is continuous and stable in quantity and rate.

(d) A signed statement that the hazardous substance release is continuous and stable in quantity and rate under the definitions in paragraph (B) of this rule and that all reported information is accurate and current to the best knowledge of the owner or operator.

(G) Where necessary to satisfy the requirements of this rule, the owner or operator of the facility or vessel may rely on recent release data, engineering estimates, the operating history of the facility or vessel, or other relevant information to support notification.

(1) All supporting documents, materials, and other information shall be kept on file at the facility, or in the case of a vessel, at an office within the state of Ohio in either the port of call, a place of regular berthing, or the headquarters of the business operating the vessel.

(2) Supporting materials shall be kept on file for a period of one year and shall substantiate the reported normal range of releases, the basis for stating that the release is continuous and stable in quantity and rate, and the other information in the initial written report, the follow-up report, and the annual evaluations required under paragraphs (D)(2), (D)(3), and (E) of this rule.

(3) Supporting information shall be made available to Ohio EPA upon request as necessary to enforce the requirements of this rule.

(H) Multiple current release of the same substance occurring at various locations with respect to contiguous plants or installations upon contiguous grounds that are under common ownership or control may be considered separately or added together in determining whether such releases constitute a continuous release or statistically significant increase under the definitions in paragraph (B) of this rule; whichever approach is elected for purposes of determining whether a release is continuous also shall be used to determine a statistically significant increase in the release.
