PLN 360/560 Environmental Impact Assessment Homework No. 4 1. An applicant has applied to the U.S. Army Corps of Engineers (USACE) for a Clean Water Act (CWA) Section 404 Permit to construct a marina at the mouth of Chaotic Creek on Bagel Bay on Lake Promise, a Water of the United States and Class \"B\" surface water in New York State. This site is located in the upper reach of a large commercial harbor used for deep-draft navigation. The project entails (1) construction of a breakwall; (2) dredging (and future maintenance dredging) of navigation entrance and creek channels; (3) installation of 50 docks with boat slips; and (4) construction of a boat launching ramp. During construction, it is estimated that a total of 60,000 cubic yards of material will be dredged and need to be managed, and about 2,500 cubic yards of fill will need to be placed in Lake Promise. Management alternatives for the dredged material include placement at an upland permitted municipal landfill, or discharge at a designated open-water site in the harbor. The site is an abandoned \"hole\" and since discharge of the dredged sediment is conceived to have benefits through reducing DDE bioaccumulation through capping and restoration of shallow water aquatic habitat, it is referred to as a habitat restoration site (HRS). The applicant had a consultant sample the sediments to be dredged for the marina as well as a lake reference area and HRS, and had the samples analyzed by a laboratory. The following is a summary of the test results that are to be submitted with the application: Contaminant Concentration in sediment sample of Concentration in Concentration in reference bulk HRS bulk marina sediment to be sediment sample sediment sample dredged Bulk Standard sediment elutriate (mg/kg)(mg/L) (mg/kg) (mg/kg) 13 0.02 Barium Cyanide Iron Mercury Dieldrin p.p\'-DDE Chlorobenzene 16 65 0.70 13,000 120 14 53 0.40 12,500 130 0.60 11,000 100 0.02 3x10-7 8x10 1.3x10 0.32 0.008 0.0034 0.12 1.3 38,000 Total organic 21,000 10,300 carbon (TOC) a. What type of CWA regulatory approvals (i.e., permits, etc.) would be required for this project? (2 pts.)
Approvals required for this project -
Storm Water permit - Clean Water Act (CWA) permit coverage for discharge of storm water runoff from the construction site which are issued throught the US Environmental protection agency\'s NPDES (national pollutant discharge elimination system) or the state NPDES authority
Permit under section 404 of the CWA issued by US Army Crops for Engineers
Resource Conservation and Recovery Act (RCRA) permit for generators of hazardous wastes (The RCRA regulations list quantities of hazardous wastes that determine whether a generator is large or small.), Storage of hazardous wastes (The RCRA regulations specify the time hazardous wastes can be stored at a site. If the storage time is exceeded, a RCRA permit is required) and Transport, treatment, and disposal of hazardous wastes (a transporter should be a registered hazardous waste transporter and the hazardous waste should be delivered to a RCRA-permitted treatment or disposal facility
Permit for Comprehensiive Environmental Response, Compensation, and Liability Act (CERCLA) or the oil pollution act
Under National Environmental Policy Act NEPA, an Environmental Assessment (EA), an Environmental Impact Statement (EIS), or both may be required
Also, Clean Air Act (CAA) requirements for mobile and stationary sources that apply to constructions activities such as standards for heavy duty trucks used during construction activities and regulations of dust emission are to be fulfilled.
