• Consumer Products at a Retail Establishment

  HSC 25501

  “Consumer product” means a commodity that is used for personal, family, or household purposes, or that is present in the same form, concentration, and quantity as a product prepackaged for distribution to a consumer for personal, family, or household purposes.  A product that is not sold for personal, family, or household use is not a “consumer product.”

  “Retail establishment” means a business that sells consumer products prepackaged for direct distribution to, and intended for use by, the end user. A retail establishment may include storage areas or storerooms in establishments that are separated from shelves for display areas but maintained within the physical confines of the retail establishment. A retail establishment does not include a pest control dealer, as defined in Section 11407 of the Food and Agricultural Code.

  “Supplier” means a manufacturer, distributor, wholesaler, or retailer in the state that sells or provides hazardous materials to a business in the state.

  HSC 25507(b)(5) Consumer products are reportable in CERS if any of the following:

  1. A consumer product handled at a facility that manufactures that product, or a separate warehouse or distribution center where there are no direct sales to consumers, or where a product is dispensed on the retail premises or,
  2. A consumer product sold at a retail establishment that has a National Fire Protection Association or “NFPA” or Hazardous Materials Identification System or “HMIS” rating of 3 or 4 and is stored, at any time, in quantities equal to, or greater than, 165 gallons for a liquid, 600 cubic feet for a gas, and 1,500 pounds for a solid. If a unified program agency determines that a consumer product stored at a retail establishment is stored at or above a reportable threshold listed in subdivision (a), and poses a significant potential hazard, the unified program agency may require the product to be reported in accordance with this chapter or,
  3. A supplier of a consumer product.  A product that is not sold for personal, family, or household use is not a “consumer product.”

  This applies for a hazardous material that is a compressed gas, at standard temperature and pressure, for which the only health and physical hazards are simple asphyxiation and the release of pressure.  Cal/EPA has developed guidance to determine if a material qualifies for this reporting threshold.

• Materials Classified as Irritant or Sensitizer Only

  The reporting quantity in CERS is >5,000 pounds for solids or >550 gallons for liquids. [HSC §25507(a)(4)]

• Lubricating Oils

  Report lubricating oil in CERS if volume of each type exceeds 55 gallons OR the total volume of all types exceeds 275 gallons.  [HSC §25507(b)(3)]

  NOTE: Used oil is subject to additional reporting requirements for hazardous waste and is thus reportable in any amount.

• Specified Medical Gases

  Report in CERS at >200 cubic feet unless the conditions below apply.

  Report in CERS if facility handles at any one time during the reporting year cryogenic, refrigerated, or compressed gas in quantities of >1000 cubic feet for oxygen, nitrogen, and nitrous oxide maintained by a physician, dentist, podiatrist, veterinarian, pharmacist, or emergency medical service provider.
