1 Exposure scenario titles consist of release activ ity followed by exposure calculation abbreviation. 2 Release activities are from engineering report's Manufactur ing (Mfg), Processing (Proc) and Use release activity labels. Multiple release activities are combined in one exposure scenario if their releases occur at same location. 3 Exposure calculations are Acute Dose Rate (ADR), Lifetime Average Daily Dose (LADD), and Probabilistic Dilution Model (PDM). There may be one, two, or all three exposure calculations per exposure scenario. CC is the aquatic concentration of concern.

## LEGEND FOR NEW CHEMICAL S EXPOSURE REPORT

This new chemicals exposure report wa s prepared by the Exposure Assessment Branch (EAB) of the Economics, Exposure and Technology Division, Office of Pollution Prevention and Toxics, USEPA. The goals of these reports are to calcula te conservative (protective) estimates of exposure endpoints for consumers, the general population, and the environment. For each exposure scenario to industrial releases, the following three endpoints are calculated: (1) maximum possible acute concentrations and doses (2) maximum possible chronic concentrations and doses (3) for water releases ≥ 20 days, the probability of exceedence of the aquatic concentration of concern These endpoints are identified by abbreviati ons on the Release Activity line, e.g., (1) max ADR , (2) max LADD , (3) max PDM . Depending on the release inputs, these e ndpoints may be calculated and presented on the same page or different pages. That is, a release activity ID of mfg; max ADR, max PDM, max LADD indicates that all the exposure endpoints were cal culated from common manufacturing release values; conversely, a release activity ID of mfg &proc; max ADR indicates that only the maximum acute exposure values were calculated for manufacturing and proce ssing releases that occurred at the same site. For each consumer product use exposure scenario, whether exposure is to the user directly or to the general population/environment, the maximum exposure values are calculated and presented together. In addition to the exposure values above, EPA policy dir ects that exposure and release values be compared to criteria threshold values for Exposure-based and PBT Exposure-based cases. Exposure-based (YX) cases (those with ≥ 100,000 kg/yr production volume) Criteria are exceeded under the following conditions: Presence in consumer product with likely exposure ≥ 3E-3 mg/kg/d exposure via air, fish ingestion or drinking water ≥ 10,000 kg/yr release to environment (post-treatment) ≥ 1,000 kg/yr release to water (post-treatment) Persistent, Bioaccumulative, Toxic (PBT) chemical s of P2B2 rating or hi gher and production volume ≥ 20,000 kg/yr Criteria are exceeded as for YX cases, with the following differences: ≥ 2,000 kg/yr release to environment (post-treatment) ≥ 200 kg/yr release to water (post-treatment) Bolding rules in the Report: Values for endpoints above th at are also health or eco concerns are bolded.
