CATEGORY--Table of Contents
 
                      Subpart B_Net Pen Subcategory
 
Sec. 451.21  Effluent limitations attainable by the application of the best practicable
control technology currently available (BPT).

    Except as provided in 40 CFR 125.30 through 125.32, any existing 
point source subject to this subpart must meet the following 
requirements, expressed as practices (or any modification to these 
requirements as determined by the permitting authority based on its 
exercise of its best professional judgment) representing the application 
of BPT:
    (a) Feed management. Employ efficient feed management and feeding 
strategies that limit feed input to the minimum amount reasonably 
necessary to achieve production goals and sustain targeted rates of 
aquatic animal growth. These strategies must minimize the accumulation 
of uneaten food beneath the pens through the use of active feed 
monitoring and management practices. These practices may include one or 
more of the following: Use of real-time feed monitoring, including 
devices such as video cameras, digital scanning sonar, and upweller 
systems; monitoring of sediment quality beneath the pens; monitoring of 
benthic community quality beneath the pens; capture of waste feed and 
feces; or other good husbandry practices approved by the permitting 
authority.
    (b) Waste collection and disposal. Collect, return to shore, and 
properly dispose of all feed bags, packaging materials, waste rope and 
netting.
    (c) Transport or harvest discharge. Minimize any discharge 
associated with the transport or harvesting of aquatic animals including 
blood, viscera, aquatic animal carcasses, or transport water containing 
blood.
    (d) Carcass removal. Remove and dispose of aquatic animal 
mortalities properly on a regular basis to prevent discharge to waters 
of the U.S.
    (e) Materials storage. (1) Ensure proper storage of drugs, 
pesticides and feed in a manner designed to prevent spills that may 
result in the discharge of drugs, pesticides or feed to waters of the 
U.S.
    (2) Implement procedures for properly containing, cleaning, and 
disposing of any spilled material.
    (f) Maintenance. (1) Inspect the production system on a routine 
basis in order to identify and promptly repair any damage.
    (2) Conduct regular maintenance of the production system in order to 
ensure that it is properly functioning.
    (g) Recordkeeping. (1) In order to calculate representative feed 
conversion ratios, maintain records for aquatic animal net pens 
documenting the feed amounts and estimates of the numbers and weight of 
aquatic animals.
    (2) Keep records of the net changes, inspections and repairs.
    (h) Training. The permittee must:
    (1) In order to ensure the proper clean-up and disposal of spilled 
material adequately train all relevant facility personnel in spill 
prevention and how to respond in the event of a spill.
    (2) Train staff on the proper operation and cleaning of production 
systems including training in feeding procedures and proper use of 
equipment.
