This Technical Development Document provides the technical background for the Phase I regulation that is issued under authority of the Uniform National Discharge Standards (UNDS) provisions of the Clean Water Act (CWA). The purpose of Phase I of UNDS is to determine those discharges that are incidental to the normal operation of Armed Forces vessels for which it is reasonable and practicable to require the use of a marine pollution control device (MPCD) on at least one vessel class, type, age, or size. An extensive data collection effort was conducted to identify vessels of the Armed Forces producing discharges incidental to normal operations and to characterize those discharges. Initial requests for information were made to each branch of the Armed Forces to obtain discharge information and to help compile a list of vessels that could be subject to UNDS requirements. EPA and DoD identified a list of 39 types of discharges incidental to the normal operations of vessels of the Armed Forces and evaluated them during Phase I of UNDS. Consultations with personnel having equipment expertise were held on each discharge to identify available data and data gaps. Sampling data were collected from various vessels, where needed, to supplement existing data. Concurrently, existing laws and regulations were reviewed, including applicable international, Federal, State, and local standards. In addition, consultation meetings were held with interested Federal agencies, States, and environmental organizations. |
