Risk assessments must evaluate potential exposure to pollutants emitted by the source via all relevant exposure routes, including ingestion of and dermal exposure to contaminated soil and ingestion of contaminated fish, drinking water, milk and meat from local farms, mother’s milk, and homegrown and locally produced produce. Assessments must be conducted using California Environmental Protection Agency’s Risk Assessment Standalone Tool, which evaluates cancer and non-cancer health effects associated with emitted pollutants.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In addition to the risk assessment requirements for major sources, the updated Guideline states that RI DEM may require applicants for preconstruction permits for certain minor stationary sources or modifications to submit risk-related documentation or analyses in conjunction with those applications and presents examples of conditions that may indicate the need for such documentation.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The proposed revised Guideline is available<span style='color:navy'> </span>on the RI DEM Office of Air Resources’ web page at:<span style='color:navy'> <a href="http://www.dem.ri.gov/programs/benviron/air/pdf/riskguid15d.pdf">http://www.dem.ri.gov/programs/benviron/air/pdf/riskguid15d.pdf</a> <o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Comments on the Guideline will be accepted until 4:00 PM on September 4, 2015 and can be submitted electronically or in hard copy to:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Barbara Morin, Supervising Environmental Scientist<o:p></o:p></p><p class=MsoNormal>Rhode Island Department of Environmental Management<o:p></o:p></p><p class=MsoNormal>Office of Air Resources<o:p></o:p></p><p class=MsoNormal>235 Promenade Street<o:p></o:p></p><p class=MsoNormal>Providence, RI 02908<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>(401) 222-4700, ext. 7012<o:p></o:p></p><p class=MsoNormal>(401) 222-2017 (fax)<o:p></o:p></p><p class=MsoNormal><a href="mailto:barbara.morin@dem.ri.gov" title="blocked::mailto:barbara.morin@dem.ri.gov">barbara.morin@dem.ri.gov</a><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Comic Sans MS"'><o:p> </o:p></span></p></div></body></html>
