Memo Wonder Group, Inc. Expansion and annual PMz.s are less than the NAAQS. The results of this analysis indicates that the proposed project will nol cause or contribute to a violation of the PMz3s NAAQS. Asummary of the risk screening assessment following NJDEP guidelines is presented below in Table 3. As shown, the combined cancer inhalation risk for total PAH is below 1 in a million (1 x 10° or 1E-06) and all hazard quotients fer individual PAH compounds are below 1, indicating negligible risk.
