Contaminated sediment from a harbor is proposed to be dredged and stored in an open confined disposal facility (CDF). The sediment concentrations of Aroclor 1242 and 1254 are 687 and 446 mg/kg, respectively. The sediment suspension in water is expected to be highest immediately after loading the CDF. The highest suspended sediment concentration expected using the selected dredged head is 490 mg/L. The area of the CDF is 1.3 × 105 m2. What is the expected air emission of Aroclor 1242. Properties for Aroclor 1242 and 1254 should be obtained from the literature
