(1) "Anhydrous product" means the theoretical product that would result if all water were removed from the actual product.(2) "Neat soap" means the solution of completely saponified and purified soap containing 20-30% water which is ready for final formulation into a finished product.(3) "Surfactant" means those methylene blue active substances amenable to measurement by the method described on page 131 of "Methods for Chemical Analysis of Water and Wastes", published 1971 by the Analytical Quality Control Laboratory of the Environmental Protection Agency. Copies of this document are available for inspection at the office of the department of natural resources, the secretary of state's office, and the office of the legislative reference bureau, and may be obtained for personal use from the Water Quality Office, U.S. EPA, 1014 Broadway, Cincinnati, Ohio, 45268.(4) "Sweet water" means the solution of 8-10% crude glycerine and 90-92% water that is a by-product of saponification or fat splitting.(5) "Normal operation" of a spray drying tower means operation utilizing formulations that present limited air quality problems from stack gases and associated need for extensive wet scrubbing, and without more than 6 turnarounds in a 30 day consecutive period, thus permitting complete recycle of waste water.(6) "Air quality restricted operation" of a spray drying tower means an operation utilizing formulations (e.g. those with high non-ionic content) which require a very high rate of wet scrubbing to maintain desirable quality of stack gases, and thus generate much greater quantities of waste water than can be recycled to process.(7) "Fast turnaround operation" of a spray drying tower means operation involving more than 6 changes of formulation in a 30 consecutive day period that are of such degree and type (e.g. high phosphate to no phosphate) as to require cleaning of the tower to maintain minimal product quality.(8) "Normal liquid detergent operations" means all such operations except those defined as fast turnaround operation of automated fill lines.(9) "Fast turnaround operation of automated fill lines" means an operation involving more than 8 changes of formulation in a 30 consecutive day period that are of such degree and type as to require thorough purging and washing of the fill line to maintain minimal product quality.(10) "BOD7" means the biochemical oxygen demand as determined by incubation at 20` C for a period of 7 days using an acclimated seed. Agitation employing a magnetic stirrer set at 200 to 500 rpm may be used.Wis. Admin. Code Department of Natural Resources § NR 294.03
