Statutory Authority: 7 Delaware Code, Chapter 60 (7 Del.C. Ch. 60)

Secretary’s Order No.: 2004-A-0033

FINAL

Reporting of a Discharge of a Pollutant or Air Contaminant

I. Background

A public hearing was held on June 25, 2003, to receive comment on proposed amendments to a regulation enacted under 7 Del.C. §6028 entitled “Reporting of a Discharge of a Pollutant or Air Contaminant”. This regulation potentially affects any person who causes or contributes to certain environmental releases and discharges. In 2002, this particular regulation was amended for the purpose of updating the list of substances to agree with the federal list and reportable quantities, as well as to clarify reporting requirements, including the amendment to §6028 mandated by Senate Substitute No. 1 for Senate Bill 33, as amended by Senate Amendment No. 2.

In preparation for the hearing, AQM held a public workshop on March 27, 2003. At both the time of the hearing and subsequent to the hearing, the Department received public comments and concerns about these proposed amendments. Following the close of the record for comments, the Air Quality Management section prepared its initial Response Document, dated September 17, 2003, which addressed comments received during the pre-hearing, hearing and post-hearing phases of this process. Supplemental Response Documents were generated and forwarded to the Hearing Officer by AQM in November of 2003 and again in February of 2004. These documents contained additional requests for clarifications to be incorporated into the formal record of this matter. Upon further review, however, the Department determined that the proposed additional clarifications represented substantive changes which were not brought before the public at the time of the June 25, 2003 hearing. Based upon that determination, all requests for supplemental changes and clarifications to the formal record in this matter were withdrawn from consideration, as illustrated in AQM’s memorandum to the Hearing Officer dated June 10, 2004. Proper notice of the hearing was provided as required by law.

After the hearing, the Department performed an evaluation of the evidence entered into the record in this matter. Thereafter, the Hearing Officer prepared his report and recommendation in the form of a memorandum to the Secretary dated June 14, 2004, and that memorandum is expressly incorporated herein by reference.

II. Findings and Conclusions

Proper notice was provided as required by law.

The Department has provided an accurate summary and reasoned analysis of all relevant comments, together with a rational proposed course of action based on the record, as presented in AQM’s Response Document of September 17, 2003, which is incorporated herein.

Additional clarifications proposed by AQM during the post-hearing period were determined to represent substantive changes which were not brought before the public at the time of the June 25, 2003 hearing; therefore, the same were formally withdrawn from consideration in this particular rulemaking process, as noted in AQM’s memorandum to the Hearing Officer dated June 10, 2004.

III. Order

In view of the above, I hereby order that the proposed amendments to 7 Del.C. §6028, “Reporting of a Discharge of a Pollutant or an Air Contaminant”, be promulgated and implemented in the manner and form provided for by law pursuant to the changes proposed prior to the hearing and as recommended in the Hearing Officer’s memorandum.

IV. Reasons

Adopting the proposed amendments to 7 Del.C. §6028, “Reporting of a Discharge of a Pollutant or an Air Contaminant”, will be beneficial to the State of Delaware, in that these amendments will add consistency and/or clarification to the existing regulations. Additionally, this rulemaking will further the policies and purposes of 7 Del.C. Ch. 60 by continuing to promulgate reasonable reporting requirements to ensure safety of the public health and environment, while taking into account industry concerns.

Section 1 - General Provisions

1.1 The purpose of this Regulation is to describe the requirements for reporting the discharge of a pollutant or an air contaminant as mandated in 7 Del.C., Section 6028.

1.2 Information obtained through the provisions of this Regulation shall be made available for public inspection in accordance with 29 Del.C., Chapter 100 and Department of Natural Resources and Environmental Control (Department) Freedom of Information Act (FOIA) regulations except where such information is of confidential nature as defined in 7 Del.C., Section 6014.

1.3 The list of chemicals and substances subject to the reporting requirements of this Regulation and the associated Delaware Reportable Quantity (DRQ) for each chemical and substance is contained in Section 3. The Department may, after providing proper public notice and an opportunity for public hearing, add or delete chemicals or substances or change the DRQ of any chemical or substance.

1.4 The reporting requirements under this Regulation are in addition to and not in lieu of, any other discharge reporting requirement found in any other state, federal, county or local government statutes, permits, regulations or ordinances.

1.5 [Reserved]

1.6 Definitions

A. "Delaware Reportable Quantity" (DRQ) – means the reportable quantity of chemicals, substances or mixtures listed in Section 3 of this regulation notwithstanding any reporting requirements by other state, federal, county or local government statutes, regulations or ordinances. To be reportable, the DRQ is based on the total quantity discharged over a rolling 24-hour period.

B. "Discharge" - means any spilling, leaking, pumping, pouring, emitting, emptying, releasing, injecting, escaping, leaching, dumping, or disposing into the environment of any chemical or substance listed in Section 3 but excludes emissions from the engine exhaust of a motor vehicle, rolling stock, aircraft, waterborne vessel or pipeline pumping station engine. Discharge includes any environmental release.

C. "Environmental Emergency Notification and Complaint Number" – means the 24-hour DNREC telephone number(s) used for reporting the discharge of a pollutant or an air contaminant.

D. “Environmental Release” – means any spillage, leakage, emission, discharge, or delivery into the air or waters or on or into the lands of this State, of any sewage of 10,000 gallons or more, oil, industrial waste, liquid waste, hydrocarbon chemical, hazardous substance, hazardous waste, restricted chemical material, vessel discharge, air contaminant, pollutant, regulated biological substance or other wastes reportable pursuant to the Comprehensive Environmental Response, Compensation and Liability Act of 1980 as amended, or this Regulation.

E. “Extremely Hazardous Substance” – means substances listed in 40 CFR Part 355 Appendices A and B as amended May 7, 1996.

F. "Heating oil" - means petroleum that is one of nine technical grades. These are: No. 1; No.2; No.4-light; No.4-heavy; No.5-light; No.5-heavy; No.6 technical grade of fuel oil; other residual fuel oils (including Navy Special Fuel Oil and Bunker C); and other fuels used as substitutes for one of these fuels such as kerosene or diesel when used for heating purposes. Heating oil is typically used in the operation of heating equipment, boilers, or furnaces.

Section 2 - Reporting Requirements

2.1 Applicability

A. Unless otherwise stated in this Section, any person who causes or contributes to an environmental release or to the discharge of an air contaminant into the air or a pollutant, including petroleum substances, into surface water, groundwater or land in excess of any DRQ specified under this Regulation, shall report such discharge to the Department as soon as the person has knowledge of said environmental release or discharge while activating the appropriate emergency site plan unless circumstances exist which make such a notification impossible. A delay in notification shall not be considered to be a violation of this Regulation when the act of reporting may delay the mitigation of the discharge and/or the protection of public health and the environment.

B. Discharge in compliance with a validly issued state or federal permit(s) or in compliance with other state and federal regulations is exempt from the reporting requirements of this Regulation. [This Regulation does not apply to natural gas and propane gas pipelines subject to overshight or regulation under the Federal Energy Regulatory commission (FERC) or the Federal Department of Transportation’s Office of Pipeline Safety (OPS).]

C. An owner or operator responsible for a transportation related discharge may meet the requirements of this Regulation by providing the information indicated in 2.4 to the 911 operator and, if applicable, to the responding Department representative at the scene. For the purposes of this paragraph, a “transportation related discharge” means a discharge during transportation when the stored chemical or substance is moving under active shipping papers and has not reached the ultimate consignee.

D. This Regulation does not apply to the proper application of a pesticide product registered under the Federal Insecticide, Fungicide, and Rodenticide Act (7 U.S.C. 136 et. seq. as amended August 3, 1996).

E. Any discharge that is continuous and stable in quantity and rate under the definitions in 40 CFR 302.8 (b) is exempt from reporting requirements of this regulation except:

(i) Initial notifications as required by 40 CFR part 302.8 (d) and (e).

(ii) “statistically significant increase” as defined in 40 CFR 302.8(b),

(iii) notification of a “new release” as defined in 40 CFR 302.8(g) (1), or

(iv) notification of a change in the normal range of the release as required under 40 CFR 302.8(g) (2).

Telephone notification required by 40 CFR 302.8 to the State of Delaware State Emergency Response Commission (SERC) shall be fulfilled by notifying the Department. Written notification reports required by 40 CFR 302.8 and sent to the EPA regional office shall serve as written notification to the State of Delaware SERC when copied to the Department.

(Reference: 40 CFR 302.8 as promulgated on July 24, 1990).

2.2 Discharges (including petroleum substances) that are wholly contained within a building are exempt from the reporting requirements of this Regulation. Should such a wholly contained discharge be discharged outside the building at a later time for any reason, that eventual discharge, when exceeding the DRQ, shall activate these reporting requirements.

2.3 [Reserved]

2.4 For the purpose of this regulation, notification of any reportable incident under Sections 2.1 or 2.3 by a person to the Department can be in person to Department staff or by telephone communication to the Department's Environmental Emergency Notification and Complaint Number. The notification must contain the following information which details the facts and circumstances of the discharge to the maximum extent practicable at the time of notice:

A. Facility name and/or location of the discharge.

B. Type of incident, e.g. discharge, fire, explosion, associated with discharge and whether assistance from outside emergency responders, e.g. 911, has been requested.

C. The chemical or substance involved with the incident of discharge including the Chemical Abstract System (CAS) number for the chemical or of the constituent chemicals when a mixture is discharged.

D. An indication of whether the chemical or chemicals are an extremely hazardous substance.

E. An estimate of the quantity of any such chemical(s) or substance(s) that was discharged into the environment.

F. The beginning time and the duration of the discharge.

G. The medium or media, e.g. soil, groundwater, surface water, air , etc., into which the discharge occurred.

H. Any known or anticipated acute or chronic health risks associated with the emergency and, where appropriate, advice regarding medical attention necessary for exposed individuals.

I. Proper precautions to take as a result of the discharge, including evacuation.

J. The name(s) and telephone number(s) of the person(s) to be contacted for further information.

K.Such other information as the Department may require.

2.5 (A) Except for petroleum substances, sewage, or infectious waste releases, as soon as practical but no later than 30 days after a release of a DRQ of a listed substance, such person, owner or operator shall provide a written follow-up report to the Department updating the information required under section 2.4 and including the following additional information to the extent known:

Part I.

i. Actions taken to respond to and contain the release in the form of a chronology,

ii. Any known or anticipated acute or chronic health risks associated with the release, and

iii. Where appropriate, advice regarding medical attention necessary for exposed individuals.

Part II.

iv. The facts and circumstances leading to the environmental release including a detailed identification of the pathway through which the discharge to the environment occurred and potential environmental impacts,

v. Measures proposed to prevent such a discharge from occurring in the future and to remedy the deficiencies, if any, in the prevention, detection, response containment, cleanup or removal plan components,

vi. Such other information which the Department may require.

Except where Part II information is of confidential nature as defined in 7 Del.C, § 6014, all written information obtained through this subsection shall be made available to Local Emergency Planning Committees (LEPCs) and the public.

(B) The Department reserves the right to require a written follow-up report for any environmental release, regardless of the substance or quantity, if there is concern for public health and safety or environmental welfare has been adversely affected. At the Department’s discretion, the Department may require said person to file a written follow-up report, within 30 days or any shorter time as required by validly issued state or federal permits or by any pertinent regulations, setting forth all details contained in Sections 2.4 and 2.5.

The written follow-up report shall be in a format approved by the Department and submitted to the appropriate addresses for report submissions provided by the Department. The Department may establish procedures for notification and submission of written reports by computerized and electronic methods, including but not limited to, the submission of information through the internet.

Section 3 - Chemicals, Substances and Mixtures and Associated Reportable Quantities.

3.1 The purpose of this Section is to detail those chemicals, substances and mixtures applicable to the reporting requirements of this Regulation and to identify the DRQ at which reporting of the chemical or substance release or discharge is required.

3.2 Table A attached to this Section contains all chemicals and chemical categories and DRQ's that are subject to the reporting requirements of this Regulation. Notification of the discharge of a DRQ of solid particles of antimony, arsenic, beryllium, cadmium, chromium, copper, lead, nickel, selenium, silver, thallium, zinc or any other solid substance on the DRQ list is not required if the mean diameter of the particles discharged is larger than 100 micrometers (0.004 inches).

3.3 When any incident of discharge occurs involving more than one (1) chemical or chemical category listed in this Section, the DRQ for the total discharge shall be the lowest DRQ of any constituent of that total, unless the mixture is known. In this case, the word "known" means that a determination of constituent levels is made either by direct testing or by calculation of the constituent level in light of the materials or processes used to generate the mixture. For incidents involving known mixtures of substances with a DRQ, the discharge is subject to these notification requirements only when a constituent substance of the mixture is discharged in a quantity equal to or greater than its DRQ.

3.4 In all cases, discharges of infectious waste, as defined in Title 7 Chapter 64 § 6402, of any quantity or of any type occurring outside of a medical or health care facility are subject to the notification requirements of Section 2.4 of this regulation and the written requirements of Section 2.5 (B).

3.5 In all cases, discharges of petroleum substances of any quantity or of any type are subject to these notification requirements unless the petroleum substance is contained in such a manner as to prevent the immediate or eventual discharge or leaking into surface water or groundwater, or is confined to the location of the discharge on an impervious surface. For discharges of petroleum substances that are contained in such a manner as to prevent the immediate or eventual discharge or leaking into surface water or groundwater or are confined to the location of the discharge on an impervious surface, the following shall apply:

A. Discharges of 25 gallons or more on land of motor fuel, jet fuel, heating oil, used oil or used petroleum substances must be reported.

B. Discharges of 150 gallons or more to land of any other petroleum substance not listed above or not uniquely identified on the Section 3 list, must be reported.

This consolidated chemical list includes chemicals subject to reporting requirements under the Emergency Planning and Community Right-to-Know Act (EPCRA), also known as Title III of the Superfund Amendments and Reauthorization Act of 1986 (SARA). Chemicals listed under 112(r) of the Clean Air Act (CAA), Section 311 of the Clean Water Act of 1980, State of Delaware’s Accidental Release Prevention Regulation, and EPCRA Section 313 are included with Delaware Reportable Quantities (DRQs). Some substances are listed as commonly known synonyms more than once or with different CAS numbers. For other synonyms and CAS numbers search the EPA Chemical Substance Registry System (CRS) (SRS)under chemical names or CAS numbers. The EPA CSR (SRS) search page can be found on the internet at: http://oaspub.epa.gov/srs/SEARCH$.STARTUP

Note: Substances with no DE must also be reported to the National Reporting Center (NRC) under federal reporting requirements with reportable quantities equal to the DRQ. The column with designation ‘DE’ means that the substance DRQ does not agree with the federal reportable quantity under CERCLA or EPCRA requirements to report to the (NRC). Check the EPA Lists of Lists or the NRC internet webpage to determine if and what reportable release quantity must be reported to the NRC independently of the State of Delaware Reporting requirements.

* No mandatory written report is required under Section 2.5 of the 6028 Reporting Regulation.

** F = Flammable substances Delaware reportable quantities apply for short term releases (immediate to one hour).

Note: Delaware reportable quantities (DRQs) are based upon EPA RCRA waste streams and unlisted hazardous wastes reportable quantities (RQs) as published in EPA List of Lists as EPA publication Number: EPA 550-B-01-003.

The term hazardous waste substance includes RCRA listed and characteristic hazardous wastes. The establishments of RQs for hazardous waste differs from the methodology applied to individual hazardous substances, as the RQ for hazardous waste is based on the results of an analysis of hazardous constituents in the waste stream. When the RQ of each hazardous constituent is established, the lowest RQ of each of these constituents then becomes the adjusted RQ for the waste stream. In the event there are constituents in the hazardous waste that are not considered hazardous substances, a reference RQ is developed for these constituents in order to assign an appropriate RQ.
