Reportable quantity

The Comprehensive Environmental Response, Compensation, and LiabiHty Act of 1980 (CERCLA) requires notification to the National Response Center of releases of quantities of hazardous substances equal to or greater than the reportable quantity (RQ) in 40 CER 302.4, which is one pound (0.454 kg). 

OSHA has a TWA standaid on a weight of Sb basis of 0.5 mg/for antimony in addition to a standard TWA of 2.5 mg/m for fluoride. NIOSH has issued a criteria document on occupational exposure to inorganic fluorides. Antimony pentafluoride is considered by the EPA to be an extremely hazardous substance and releases of 0.45 kg or more reportable quantity (RQ) must be reported. Antimony triduoride is on the CERCLA bst and releasing of 450 kg or more RQ must be reported. 

Shipment of hydrazine solutions is regulated in the United States by the Department of Transportation (DOT) which classifies all aqueous solutions between 64.4 and 37% N2H4 as "Corrosive" materials with a subsidiary risk of "Poison". Hydrazine has been identified by both the Environmental Protection Agency and the DOT as a hazardous material and has been assigned a reportable quantity (RQ) of 0.450 kg (1 lb) if spilled. Dmms for the shipment of these solutions must bear both the DOT specification "Corrosive" and "Poison" labels in association with the markings "RQ Hydrazine Aqueous Solution UN 2030." Aqueous solutions of 37% concentration or less are a hazard Class 6.1, UN 3293, Packing Group III and require "Keep Away From Food" placards and labels. 

Potassium permanganate under RCRA definition meets the criteria of an ignitable waste, and if discarded is considered a ha2ardous waste. The reportable quantity (RQ) (220) for potassium permanganate is 45.4 kg (100 lbs) and releases into the environment greater than this value must be reported to the U.S. Coast Guard National Response Center.

In the United States, the reportable quantity of 1-propanol for spills under CERCLA "Superfund" is 100 Ib/d (45.4 kg/d). However, no reportable quantity is assigned for transport (43). The substance is on the list for atmospheric standards, as defined iu 40 CER 60.489 (47). The iatent of these standards is to require all newly constmcted, modified, and reconstmcted manufacturiug units to use the best demonstrated system of continuous emission reduction for equipment leaks of volatile organic compounds (47). 1-Propanol is also on the right-to-know regulations of the states of Connecticut,... 

Release Reporting. Both the Comprehensive Environmental Response, Compensation, and Liabihty Act (CERCLA) and EPCRA have requirements for reporting releases to the air, ground, or water. Lists of reportable chemicals or family of chemicals and their reportable quantity (RQ) have been issued (9). A reportable quantity is the amount, in pounds or kilograms, below which a release does not have to be reported. CERCLA requires only the reporting of releases from the CERCLA Hst however, EPCRA requires reporting releases of both EPCRA- and CERCLA-Hsted substances.

Under the Comprehensive Environmental Response, Compensation, and LiabiHty Act (CERCLA)/RCRA regulations in effect at the end of 1986 bromine is regulated as a hazardous waste or material. Therefore, it must be disposed of in an approved hazardous waste faciHty in compliance with EPA and/or other appHcable local, state, and federal regulations and should be handled in a manner acceptable to good waste management practice. The reportable quantity is 45.4 kg for corrosivity (62). 

The following shipping paper is only illustrative since it may vary in format. However, all descriptions will be basically Ihe same. You should look for this type of eniry lo determine the shipping name of the haiardous material, its classification, its 10 number (10 No.), and a reportable quantity notation (RO or RO-number) for use in reporting spill incidents to the National Response Center. With very few exceptions, shipping papers identifying haiardous materials are required when they are being transported ... 

Four predefined subcategories for reporting quantities released to land within the boundaries of the facility are provided. Do not report land disposal at off-site locations in this section. 

You must report in this section the total annual quantity of the chemical sent to any of the off-site disposal, treatment, or storage facilities for which you have provided an address In Part II. You are not required to report quantities of the chemical sent off-site for purposes of recycle or reuse. Report the amou nt of the toxic chemical transferred off-site after any on-site treatment or removal is completed. Report zero for releases of listed acids and bases if they have been neutralized to pH 6-9 prior to discharge to a POTW. See the discussion under Section 5.3, Discharges to Receiving Streams or Water Bodies (see page 21). 

Indicates if notification requirements apply to the chemical released Identifies notification requirements for release of reportable quantities of chemicals (e.g., CERCLA, SARA). 

This decision is one that must be made after carefully considering all of the circumstances and, of course, based on the requirements. The reportable quantity rules may come into play. The principle behind these requirements is that the more dangerous a material might be to personnel, surroundings or the environment, the smaller the reportable quantity. A competent person should review each occurrence to help determine the appropriate action. Sometimes, even a very minute spill must be reported. If doubts occur as to the applicability of the requirements, take the safe rather than sorry stance. 

Under this provision, facilities should notify the LEPC and consequently the SERC of any possible environmental release of specific chemicals. The specific chemicals referred to in SARA Title III are found on the Extremely Hazardous Substance List (40 CER 355) and the Reportable Quantity List (the Comprehensive Environmental Response, Compensation, and Liability Act [CERCLA] Section 103 [a]). 

CERCLA requires tlie person in charge of a vessel or facility to notify the National Respan.se Center (NRC) inunediately when there is a release of a designated hazardous substance in an amount equal to or greater than the reportable quantity. CERCLA establishes the reportable quantity for releases of designated liazardous substances at one pound, unless otherwise specified. To ensure that the need for response can be evaluated and any response can be undertaken in a timely fashion, such releases require notification to government officials.

Notification to the NRC is required for releases equal to or greater than the reportable quantity of a RCRA hazardous waste. If the waste also is on the CERCLA list, that reportable quantity applies. If not, the reportable quantity is 100 pounds if the waste is ignitable, corrosive, reactive, or toxic.
