Section 50.44 - Production Unit Information Required in Each PlanFor each production unit, toxics users shall determine or develop, and include in the plan, the following information:
(1) a process flow diagram in accordance with the following:(a) The process flow diagram shall be a visual representation of the movement of covered toxics through the process or processes within the production unit, including, but not limited to, covered toxics that flow into the process or processes and covered toxics that flow out of the process or processes as byproducts or products and covered toxics that are released to the environment as emissions or transferred off-site as emissions. The process flow diagram shall account for each manufacturing or process step in the production unit, and shall include waste treatment activities, and recycling activites that are not integral to the production unit, associated with the production unit. The process flow diagram may represent the movement of substances or other materials that are not covered toxics through the process or processes within the production unit.(b) The number assigned to the production unit as reported in the facility's toxics use report due on the same date that the plan summary is due shall appear on the process flow diagram.(c) The process flow diagram shall present the movement of each covered toxic through the production unit, including, but not limited to, each general location at which the covered toxic enters the production unit and each general location at which the covered toxic exits the production unit as a byproduct, emission, or product.(2) the following amounts, and a statement of the estimation methods used to determine these amounts: (a) the total amount, and the amount per unit of product, of each covered toxic manufactured, processed, or otherwise used;(b) the total amount, and the amount per unit of product, of each covered toxic generated as a byproduct;(c) the total amount, and the amount per unit of product, of each covered toxic released or transferred off-site as an emission.(3) the unit of product associated with the production unit as reported in the toxics use report due on the date that the plan summary is due.(4) for each toxic, a statement explaining the purpose that the toxic serves in the production unit;(5) for each byproduct identified on the process flow diagram developed pursuant to 310 CMR 50.44(1), toxics users shall determine the amount of byproduct treated on-site, treated off-site, recycled on-site, recycled off-site, disposed of on-site, disposed of off-site, or released.(6) for each emission identified in the process flow diagram developed pursuant to 310 CMR 50.44(1), toxics users shall determine, for each environmental media, the amount of emissions released to the environment or transferred off-site, and the amount of emissions treated off-site treatment, recycled off-site, disposed of on-site or disposed of off-site.(7) the cost of the use of each covered toxic calculated in accordance with 310 CMR 50.46A.
