Use the Comments page at the end of Part E to do the following: provide additional information as requested in certain questions within Part E; indicate atypical data (e.g., if 2009 information is not representative of normal operations); and note methods used to make best engineering estimates in the event that exact data are not available. **INSTRUCTIONS** Complete Part E of the questionnaire for your plant. As you are completing the electronic form, note the following: W hen you enter your plant name and plant ID on the Part E TOC tab, all name and ID fields throughout Part E will automatically populate. Refer to the overall questionnaire instructions, the glossary, and the acronym list for assistance with completing Part E. Please provide all free response answers in the highlighted yellow areas. Throughout Part E, you may need to make copies of certain sections/questions. Instructions are provided throughout Part E regarding making copies. Note that steam electric generating unit or metal cleaning operation names must be populated on the copied tab or section, located in the upper right corner under "Plant ID" and "Plant Name", in order to correlate the requested information with the steam electric generating unit or metal cleaning operation.

**CBI? E1-1.**  (Continue) (Skip to next Questionnaire Part) 1. Metal Cleaning Operations Complete Part E of the questionnaire for your plant. This part collects information on operations that produce metal cleaning wastes at the plant. Metal cleaning wastes include any process wastewaters resulting from cleaning [with or without chemical cleaning compounds] any metal process equipment, including, but not limited to, boiler tube cleaning, boiler fireside cleaning, and air heater cleaning. This part also collects information on combined cycle combustion turbine and air compressor cleaning, and soot blowing. For Part E of the questionnaire, report all soot blowing operations that use water or steam during the cleaning event. Has the plant generated any wastes from cleaning metal process equipment associated with fossil- or nuclear-fueled steam electric generating units since January 1, 2000? Yes Yes No

**CBI? E3-1.**  **Example:** The plant uses citric acid to remove copper deposits and iron oxides from the steel tube surfaces of the boiler. The citric acid is diluted to a pH of 3.5 and then used for cleaning in a two-stage process. In the first stage, the citric acid dissolves iron oxides. In the second stage anhydrous ammonia is added to raise the pH of the cleaning solution between 9 and 10 and air is bubbled through the solution to dissolve copper deposits. Metal Cleaning Operation ID: Complete Section 3 (Questions E3-1 through E3-8) for each type of metal cleaning operation performed on the steam electric generating unit, which is identified in Tables E-1 and E-2 of Section 2. Make a copy of Section 3 using the "Copy Section 3" button below. Enter the steam electric generating unit ID under the section heading above (use steam electric generating unit IDs assigned in Table A-8). In addition, enter the metal cleaning operation ID performed on the steam electric generating unit (use the IDs from Tables E-1 and E-2). Please provide all free response answers in the highlighted yellow areas.
In the space below, provide a description of the process equipment cleaning operation. Include the type of equipment and metal cleaned, any chemical preparation steps (e.g., diluting the chemical prior to use), and a short description of the cleaning operation.
