Toxic Chemicals Release Reporting-Emissions Inventory (Section 313)... 

Ehminating chemicals of concern often starts as a reactive strategy but it is an important first step on the path to implementing greener chemical inventories. In this section, we discuss two initiatives that focus on eliminating chemicals of concern. While we use an example from a very large company, their approach can be applied by small and large businesses ahke. 

F. X-ray Powder Difi action Search System. Compounds that fail to crystallize may still be examined by X-ray diffraction, because non-crystalline materials, as powders, give characteristic diffraction patterns. A collection of powder diffraction patterns proves to be a very effective means by which to identify materials and indeed, one of the very earliest search systems in chemical analysis was based upon such data by Hanawalt (21) over forty years ago. The importance of these data in TSCA can be seen by examining the TSCA Inventory regulations for treatment of confidential chemicals (22). Section 710.7 of these regulations indicates that EPA intends to rely on powder diffraction data to assure the validity and seriousness of a manufacturers request for treating information on a chemical as confidential. 

This section contains information on several of the various science-based drivers that provide a platform to facilitate the use of science in decision making. The drivers included in this section are Chemical Inventories, TSCA, Hazard x Exposure = Risk, Risk Assessments, and Risk vs. Benefit. 

The Canadian new chemicals program uses two chemical inventories, the Domestic Substances List (DSL) and the Non-Domestic Substances List (NDSL). The DSL includes substances that were, between January 1, 1984, and December 31, 1986, in Canadian commerce, used for manufacturing purposes, or manufactured in or imported into Canada.17 It contains about 23,000 substances. One of the initiatives in the Canadian Environmental Protection Act, 1999 (CEPA, 1999) requires the Minister of the Environment and the Minister of Health to categorize (Section 73, CEPA 1999) and then if necessary, conduct screening assessments (Section 74, CEPA 1999) of substances listed on the DSL to determine whether they are toxic or capable of becoming toxic as defined in the Act. The NDSL is a list of substances not on DSL but in commerce elsewhere in the world.18 The NDSL contains more than 58,000 entries. 

The non-confidential AICS can be accessed on-line via the NICNAS Web site. Alternatively, a request to search the AICS can be made to NICNAS. Furthermore, a search of the confidential section of the AICS can be requested but only through this mechanism. The AICS is also available on the Chemical Abstract Services Chemlist database or National Chemical Inventories (NCI) [4]. 

The documentation and periodie eonfirmation and validation of inventory records can be performed by the chemical inventory system mentioned in Section 2.3, Inventory and Tracking. 

Section 4.1 consolidates the inventory and tracking requirements for the workplace, and includes specific regulatory reporting requirements. Section 4.2 consolidates those requirements that do not directly require an inventory of hazardous chemicals, but for which use of a chemical inventory and tracking system would be necessary for compliance with mandatory standards, or would facilitate compliance. 

A current inventory of chemicals is maintained for the HCF through the use of the SNL Chemical Inventory System (CIS) as described in Chapter 6, Section U of the SNL ES H Manual (SNL 1998). Managers are required to keep an inventory of chemicals stored or used and to maintain a current CIS inventory. Locations where chemicals are used or stored are identified in the CIS. The CIS also tracks the status and ownership of these chemical use/storage locations. 

Examine your chemical inventory to ensure it is up to date for use by emergency personnel (see Section 5.3.1). 

Tier l/Tier II chemical inventory reporting — Section 312... 

Under EPCRA Section 312, if a facility has hazardous chemicals at or above the reporting threshold specified at 40 CFR Part 370, the facility owner or operator is required to submit an emergency and hazardous chemical inventory form, also known as Tier I or Tier II... 

EPCRA sections 311 and 312 require a facility at which a hazardous chemical, as defined by the Occupational Safety and Health Act, is present in an amount exceeding a specified threshold to submit to the SERC, LEPC and local fire department safety data sheets (SDSs) or lists of SDSs and hazardous chemical inventory forms (also known as Tier I and II forms). This information helps the local government respond in the event of a spill or release of the chemical.
