PART 451_CONCENTRATED AQUATIC ANIMAL PRODUCTION POINT SOURCE
CATEGORY--Table of Contents
 
      Subpart A_Flow-Through and Recirculating Systems Subcategory
 
Sec. 451.11  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) Solids control. The permittee must:
    (1) 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 in 
order to minimize potential discharges of uneaten feed and waste 
products to waters of the U.S.
    (2) In order to minimize the discharge of accumulated solids from 
settling ponds and basins and production systems, identify and implement 
procedures for routine cleaning of rearing units and off-line settling 
basins, and procedures to minimize any discharge of accumulated solids 
during the inventorying, grading and harvesting aquatic animals in the 
production system.
    (3) Remove and dispose of aquatic animal mortalities properly on a 
regular basis to prevent discharge to waters of the U.S., except in 
cases where the permitting authority authorizes such discharge in order 
to benefit the aquatic environment.
    (b) Materials storage. The permittee must:
    (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.
    (c) Structural maintenance. The permittee must:
    (1) Inspect the production system and the wastewater treatment 
system on a routine basis in order to identify and promptly repair any 
damage.
    (2) Conduct regular maintenance of the production system and the 
wastewater treatment system in order to ensure that they are properly 
functioning.
    (d) Recordkeeping. The permittee must:
    (1) In order to calculate representative feed conversion ratios, 
maintain records for aquatic animal rearing units documenting the feed 
amounts and estimates of the numbers and weight of aquatic animals.
    (2) Keep records documenting the frequency of cleaning, inspections, 
maintenance and repairs.
    (e) 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 
and wastewater treatment systems including training in feeding 
procedures and proper use of equipment.
