II. Why Did EPA Conduct the Study?

On July 31, 2008, Public Law (Pub. L.) 110-299 was signed into law. It generally provided a two-year moratorium for non-recreational vessels less than 79 feet in length and all commercial fishing vessels regardless of length, from the requirements of the National Pollutant Discharge Elimination System (NPDES) program to obtain a permit in order to authorize discharges incidental to the normal operation of those vessels. Additionally, Public Law 110-299 directed the United States Environmental Protection Agency (EPA) to study the impacts of discharges incidental to the normal operation of those vessels. Specifically, the law directs the agency to study and evaluate the impacts of:

(1) Any discharge of effluent from properly functioning marine engines;

(2) Any discharge of laundry, shower, and galley sink wastes; and

(3) Any other discharge incidental to the normal operation of a vessel.

Congress mandated that EPA include the following in the study:

(1) Characterizations of the nature, type, and composition of the discharges for:

a. Representative single vessels; and

b. Each class of vessels;

(2) Determinations of the volume (including average volumes) of those discharges for:

a. Representative single vessels;

b. Each class of vessels;

(3) A description of the locations (including the more common locations) of the discharges;

(4) Analyses and findings as to the nature and extent of the potential effects of the discharges, including determinations of whether the discharges pose a risk to human health, welfare, or the environment, and the nature of those risks;

(5) Determinations of the benefits to human health, welfare, and the environment from reducing, eliminating, controlling, or mitigating the discharges;

(6) Analyses of the extent to which the discharges are currently subject to regulation under Federal law or a binding international obligation of the United States.

The law expressly excludes certain discharges from the scope of the study: discharges from vessels owned and operated by the Armed Forces; discharges of sewage from vessels; and discharges of ballast water.

Congress may find the information in this report useful as it considers how best to address discharges incidental to the normal operation of those types of vessels studied. Currently, discharges incidental to the normal operation of certain other types of vessels are regulated under two different regimes in the Clean Water Act. First, incidental discharges from non-recreational, non-fishing vessels larger than 79 feet currently are regulated under the National Pollution Discharge Elimination System (NPDES) permitting program. Second, Congress has chosen to exempt incidental discharges from certain other vessels from NPDES permitting and instead provided for the development and implementation of national standards or management practices as appropriate. In particular, discharges incidental to the normal operation of vessels of the US armed forces are subject to the Uniform National Discharge Standard (UNDS) program established under Section 312 (n) of the Clean Water Act and are exempt from NPDES permitting. Additionally, due to passage of the Clean Boating Act in 2008, discharges incidental to the normal operation of recreational vessels also are exempt from NPDES permitting and will instead have to meet national best management requirements and performance standards established under Section 312 (o) of the Clean Water Act. Finally, in lieu of NPDES permitting, discharges of vessel sewage are subject instead to regulation under sections 312(b)-(m) of the Clean Water Act.

The objective of the draft report is to provide a scientifically informative, policy neutral document to inform Congress about discharge characteristics from the types of vessels studied. As Congress considers the result of this study, they may take into account various Federal regulatory regimes or other options. Congress may use the information in this report to extend the permitting moratorium for these vessels, to establish an alternate regulatory regime, or to do nothing, allowing the moratorium to expire, thereby requiring NPDES permitting coverage for these 140,000 vessel operators.

III. Overview of the Study's Methods and Findings

EPA estimates there are nearly 140,000 vessels in the United States subject to the permitting moratorium established under Public Law 110-299 (hereinafter referred to as “study vessels”). Approximately one-half of these vessels are commercial fishing vessels involved in activities such as fish catching (e.g., longliner, shrimper, trawler) and charter fishing. The other half is distributed among a variety of vessel classes, including passenger vessels (e.g., water taxis, tour boats, harbor cruise ships, dive boats), utility vessels (e.g., tug/tow boats, research vessels, offshore supply boats), and freight barges.

In order to complete this study, EPA conducted literature reviews, sampled vessel discharges, and used existing data from other EPA data collection efforts and other government data sources to inform its analysis. To select specific vessel classes for sampling, EPA first developed a list of commercial vessel classes. Next, EPA eliminated those vessel classes believed to consist primarily of vessels greater than 79 feet in length, with the exception of commercial fishing vessels. Examples of vessel classes eliminated because of their size included cable laying ships, cruise ships, large ferries, and oil and petroleum tankers. With the exception of fishing vessels, vessels over 79 feet are outside the scope of the Act's permitting moratorium and are generally subject to EPA's existing Vessel General Permit. Next, EPA eliminated vessel classes that have historically been subject to NPDES permitting, including stationary seafood processing vessels and vessels that can be secured to the ocean floor for mineral or oil exploration. After screening out these vessel classes, EPA selected a subset of priority vessel classes to sample including commercial fishing boats, tug/tow boats, water taxis, tour boats, recreational vessels used for nonrecreational purposes, and industrial support boats less than 79 feet in length. EPA selected these vessel classes because they represent a cross section of discharges and have the potential to release a broad range of pollutants.

EPA sampled wastewater discharges and gathered shipboard process information from 61 vessels in nine vessel classes. These classes included fishing vessels, tugboats, water taxis, tour boats, towing/salvage vessels, small research vessels, a fire boat, and a Start Printed Page 10479supply boat. EPA sampled more commercial fishing vessels than any other vessel class due to the large number of fishing vessels subject to the Public Law 110-299 permitting moratorium. Vessels were sampled in 15 separate cities and towns in nine States across multiple geographic regions, including New England, the Mid-Atlantic, the Gulf Coast, the Mississippi River, and Alaska.

EPA sampled a total of nine discharge types from the various vessel classes. These were bilgewater, stern tube packing gland effluent, deck runoff and/or washdown, fish hold effluent (both refrigerated seawater effluent and ice slurry), effluent from the cleaning of fish holds, graywater, propulsion and generator engine effluent, engine dewinterizing effluent, and firemain effluent.

EPA typically sampled one to four discharge types on each vessel, depending on applicability, accessibility, and logistical considerations. Vessel discharge samples were analyzed for a variety of pollutants, including classical pollutants such as biochemical oxygen demand (BOD5), total suspended solids (TSS), residual chlorine, and oil and grease; nutrients; total and dissolved metals; volatile and semivolatile organic compounds (VOCs and SVOCs); nonylphenols ethoxylates (used as surfactants in detergents), which are converted to nonylphenols (a class of endocrine-disrupting compounds); and pathogen indicators (i.e., E. coli, enterococci, fecal coliforms).

EPA found that some vessel discharges from commercial fishing vessels and commercial vessels less than 79 feet in length may have the potential to impact the aquatic environment and/or human health or welfare. The discharges with the greatest potential to impact surface water quality include deck washdown, fish hold effluent, graywater, bilgewater, and marine engine effluent. Review of available literature also indicates that leachate from antifouling hull coatings used on certain vessels to prevent buildup of organisms, such as barnacles and algae, as well as underwater hull cleaning, also likely impact surface water quality, particularly in areas where a large number of vessels are concentrated in a relatively small water body.

Using the results obtained in this study, EPA used a simple model to evaluate how the nine vessel discharge types EPA sampled may impact water quality in a large, hypothetical harbor. Based on this evaluation, EPA determined that the incidental discharges from study vessels are not likely to solely cause an exceedance of any National Recommended Water Quality Criteria (NRWQC) to a relatively large water body. This finding suggests that these discharges are unlikely to pose acute or chronic exceedances of the NRWQC across an entire large water body. However, since many of the pollutants present in the vessel discharges were at end-of-pipe concentrations that exceeded an NRWQC, there is the potential for these discharges to contribute a water quality impact on a more localized scale. The study results indicate that total arsenic and dissolved copper are the most significant water quality concerns for the study vessels as a whole, and that they are more likely than other pollutants to contribute to exceedances of water quality criteria. This is especially true if there are other sources of pollutants or the receiving water already has high background concentrations.

IV. Request for Public Input and Comment

In addition to generally requesting comment on all aspects of the draft report, in order to maximize the quality of the report, EPA is specifically requesting comment on the following:

(1) Are there additional existing data or data sources which EPA should incorporate into or analyze in the final report? If so, please provide the specific data sets, papers, and/or citations EPA should consider.

(2) Did EPA accurately summarize how these vessels generate these discharges, and accurately summarize how mariners and fishermen manage the discharges (e.g., fishermen in the Northeast holding bilgewater discharges until they are more than 3 nm from shore)?

(3) Did EPA present the information clearly and concisely? Do you have suggestions to better present these data for both technical and non-technical audiences?

(4) Should EPA consider other approaches to summarizing the data collected for this study, and if so, what specific alternative approaches are suggested?

(5) Are there additional data sources that identify specific environmental impacts that result from discharges incidental to normal operation of commercial fishing vessels and other non-recreational vessels less than 79 feet in length (other than ballast water)? If so, please provide the specific data sets, papers, and/or citations EPA should consider.

(6) Are there any additional existing data sources outlining usage patterns and discharge locations of commercial fishing vessels and other non-recreational vessels less than 79 feet in length that EPA should consider? If so, please provide specific data sets, papers, and or citations for EPA review.

(7) Has EPA sufficiently analyzed the extent to which the discharges are currently subject to regulation under Federal law or a binding international obligation of the United States? Does the report appropriately convey which discharges and vessel types are already regulated and unregulated?
