How were the 5,100 mg EPH/kg residential exposure scenario and the 54,000 mg EPH/kg non-residential exposure scenario criteria derived?
The 5,100 mg EPH/kg residential exposure scenario and 54,000 mg/EPH/kg non-residential exposure scenario values are based on protection from noncarcinogenic health effects at a hazard index of 1 and only apply to discharges of No. 2 fuel oil and diesel fuel oil. These values are based solely on effects via the ingestion-dermal exposure pathway. Potential inhalation exposure pathway concerns are addressed by evaluating naphthalene, and potential impact to ground water exposure pathway concerns are addressed by evaluating 2-methylnaphthalene. A field study was conducted between July and August 2007 at various sites located throughout New Jersey (described in response to Question #10 below). The purpose of the field study was to determine a typical chemical composition of No. 2 fuel oil. Based on this average composition, the health-based criteria were developed. new and additional information, and has been modified to the current value of 5,100 mg/kg. The SRP decided to take the conceptu
