The cumulative hazard and risk of indoor air concentrations for this industrial property is listed below. After the first sampling results ODOT asked the laboratory to report the estimated values that are less than their reporting limit (RL), but above their equipment s method of detection (MDL). The goal was to see if any traces of chemicals could possibly exist at a sample location in order to learn more about the site. KEY CHART TERMS Residential ppbv = units are measured in parts per billion by volume (ppbv) ppbv = parts per billion by volume EMEG = environmental media evaluation guide (ATSDR) ATSDR = Agency for Toxic Substances and Disease Registry Chronic (long-term) = exposure is considered more than a year (ATSDR) Intermediate = exposure greater than 14 days and less than a year (ATSDR) MRL= Minimal Risk Level (ATSDR) CREG= Cancer Risk Evaluation Guide (ATSDR) OSWER = Office of Solid Waste and Emergency Response for US. EPA 10-5 = Theoretical additional lifetime cancer risk calculation for chronic inhalation exposure at 10-5 equals an additional cancer risk of 1 in 100,000 persons. EPA = U.S. Environmental Protection Agency RfC = Reference Concentration (EPA) ND = The chemical was not detected above the reporting limit (RL) J = The chemical concentration is an estimated value below the laboratory reporting limit but above the method detection limit (MDL) UJ = The chemical concentration was not detected at or above the method detection limit (MDL) OHIO ENVIRONMENTAL PROTECTION AGENCY: CONTACT PERSON: Amber Kent Finkelstein, Public Involvement Coordinator, Ohio EPA Public Interest Center; Amber.Finkelstein@epa.state.oh.us or (614) 644-2160.
