(a) You must comply with the reporting requirements of this part if the Occupational Safety and Health Administration's (OSHA) Hazard Communication Standard (HCS) requires your facility to prepare or have available a Safety Data Sheet (SDS) for a hazardous chemical and if either of the following conditions is met:
Note 1 to paragraph (a) introductory text. OSHA's Material Safety Data Sheet or MSDS requirement was renamed to be the Safety Data Sheet or SDS requirement. The terms MSDS and SDS are synonymous. The EPCRA statutory MSDS requirements will be referred to as the SDS requirements within this regulation. (77 FR 17693; March 26, 2012)
(1) A hazardous chemical that is an Extremely Hazardous Substance (EHS) is present at your facility at any one time in an amount equal to or greater than 500 pounds (227 kg—approximately 55 gallons) or the Threshold Planning Quantity (TPQ), whichever is lower. EHSs and their TPQs are listed in appendices A and B of 40 CFR part 355.
(2) A hazardous chemical that is not an EHS is present at your facility at any one time in an amount equal to or greater than the threshold level for that hazardous chemical. Threshold levels for such hazardous chemicals are:
(i) For any hazardous chemical that does not meet the criteria in paragraph (a)(2)(ii) or (iii) of this section, the threshold level is 10,000 pounds (or 4,540 kg).
(ii) For gasoline at a retail gas station (For purposes of this part, retail gas station means a retail facility engaged in selling gasoline and/or diesel fuel principally to the public for motor vehicle use on land.), the threshold level is 75,000 gallons (approximately 283,900 liters) (all grades combined). This threshold is only applicable for gasoline that was in tanks entirely underground and that were in compliance at all times during the preceding calendar year with all applicable Underground Storage Tank (UST) requirements at 40 CFR part 280 or requirements of the state UST program approved by the Agency under 40 CFR part 281.
(iii) For diesel fuel at a retail gas station (For purposes of this part, retail gas station means a retail facility engaged in selling gasoline and/or diesel fuel principally to the public for motor vehicle use on land.), the threshold level is 100,000 gallons (approximately 378,500 liters) (all grades combined). This threshold is only applicable for diesel fuel that was in tanks entirely underground and that were in compliance at all times during the preceding calendar year with all applicable UST requirements at 40 CFR part 280 or requirements of the state UST program approved by the Agency under 40 CFR part 281.
(b) The threshold level for responding to the following requests is zero.
(1) If your LEPC requests that you submit an SDS for a hazardous chemical for which you have not submitted an SDS to your LEPC; or
(2) If your LEPC, SERC, or the fire department with jurisdiction over your facility requests that you submit Tier II information.
(a) You must report any hazardous chemical for which you are required to prepare or have available an SDS under OSHA HCS that is present at your facility equal to or above the applicable threshold specified in § 370.10. (specific exemptions from reporting are in § 370.13)
(b) The EPA has not issued a list of hazardous chemicals subject to reporting under this part. A substance is a hazardous chemical if it is required to have an SDS and meets the definition of hazardous chemical under the OSHA regulations found at 29 CFR 1910.1200(c).
You do not have to report substances for which you are not required to have an SDS under the OSHA regulations or that are excluded from the definition of hazardous chemical under EPCRA section 311(e). Each of the following substances are excluded under EPCRA section 311(e):
(a) Any food, food additive, color additive, drug, or cosmetic regulated by the Food and Drug Administration.
(b) Any substance present as a solid in any manufactured item to the extent exposure to the substance does not occur under normal conditions of use.
(c) Any substance to the extent it is used:
(1) For personal, family, or household purposes, or is present in the same form and concentration as a product packaged for distribution and use by the general public. Present in the same form and concentration as a product packaged for distribution and use by the general public means a substance packaged in a similar manner and present in the same concentration as the substance when packaged for use by the general public, whether or not it is intended for distribution to the general public or used for the same purpose as when it is packaged for use by the general public;
(2) In a research laboratory or hospital or other medical facility under the direct supervision of a technically qualified individual; or
(3) In routine agricultural operations or is a fertilizer held for sale by a retailer to the ultimate customer.
(a) For a mixture containing a hazardous chemical, use the following table to determine if a reporting threshold is equaled or exceeded, and to determine how to report:
| If your mixture contains a hazardous chemical | To determine if the threshold level for that hazardous chemical is equaled or exceeded you must | If the threshold level for that hazardous chemical is exceeded, then you must |
|---|---|---|
| (1) That is an EHS | Determine the total quantity of the EHS present throughout your facility at any one time, by adding together the quantities present as a component in all mixtures and all other quantities of the EHS You must include the quantity present in a mixture even if you are also counting the quantity of that particular mixture toward the threshold level for that mixture. |
Report the EHS component:
Submit an SDS for the EHS as provided under § 370.30 or include the EHS on the list of chemicals submitted in lieu of the SDS. And submit Tier I or Tier II information for the EHS as provided under § 370.40. Or |
|
Report the mixture itself:
Submit an SDS for the mixture as provided under § 370.30 or include the mixture on the list of chemicals submitted in lieu of the SDS. And submit Tier I or Tier II information for the mixture as provided under § 370.40. If you report the mixture itself, then provide the total quantity of that mixture |
||
| (2) That is not an EHS | Determine either:
The total quantity of the hazardous chemical present throughout your facility at any one time by adding together the quantity present as a component in all mixtures and all other quantities of the hazardous chemical You must include the quantity present in a mixture even if you are also applying that particular mixture as a whole toward the threshold level for that mixture Or |
Report the non-EHS hazardous chemical component:
Submit an SDS for the non-EHS hazardous chemical as provided under § 370.30 or include the non-EHS on the list of chemicals submitted in lieu of the SDS. And submit Tier I or Tier II information for the non-EHS hazardous chemical as provided under § 370.40. Or |
| The total quantity of that mixture present throughout your facility at any one time |
Report the mixture itself:
Submit an SDS for the mixture as provided under § 370.30 or include the mixture on the list of chemicals submitted in lieu of SDS. And submit Tier I or Tier II information for the mixture as provided under § 370.40. If you report the mixture itself, then provide the total quantity of that mixture. |
(b) For each specific mixture, the reporting option used must be consistent for both SDS and inventory reporting, unless it is not possible to do so. This means that if you report on a specific mixture as a whole for SDS reporting, you must report on that mixture as a whole for inventory reporting too (unless it is not possible). SDS reporting and inventory reporting are discussed in detail in subpart C of this part.
(c) To determine the quantity of an EHS or a non-EHS hazardous chemical component present in a mixture, multiply the concentration of the hazardous chemical component (in weight percent) by the weight of the mixture (in pounds). You do not have to count a hazardous chemical present in a mixture if the concentration is less than or equal to 1%, or less than or equal to 0.1% for a carcinogenic chemical.
