PART E. WASTES FROM CLEANING METAL PROCESS EQUIPMEN T

Use the Comments page at the end of Part E to do the following: provide additional

information as requested in certain questions within Par t E; indicate atypical data (e.g., if

2009 information is not representative of normal oper ations); 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: When you enter y our plant name and plant ID on the

Part E TOC tab, all name and ID fields throughout Pa rt E will automatically populate.

Refer to the overall questionnaire instructions, the gl ossary, and the acronym list for

assistance with completing Part E.

Please provide all free response answers in the highligh ted yellow areas. Throughout

Part E, you may need to make copies of certain sections/qu estions. Instructions are

provided throughout Part E regarding making copies. No te 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 "Pl ant ID" and "Plant Name", in order

to correlate the requested information with the steam electric generating unit or metal

cleaning operation.

This part collects information on operations thatproduce metal cleaningwastes at the plant. Metal cleaning wastes includeanyprocess wastewatersresulting from cleaning [with or without chemicalcleaning 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 andair compressor cleaning,and soot blowing. For Part E of the questionnaire,report all soot blowing operations that use water or steam during thecleaning event.Has the plant generated any wastes from cleaning metal process equipment associated with fossil- or nuclear-fueled steamelectric generating units since January 1, 2000?YesYesNoE-1Approved: May 20, 2010Steam Electric QuestionnairePart E.

In addition, please note whether ornot each type of cleaning operation occurs at the plant.NOTE: “Typical Dose Concentration” refers to the average concentration of the chemical within the cleaning water and "cleaning event" refers to one instance in which the plant performs a cleaning operationon metal process equipment.Complete Section 2 (Questions E2-1 and E2-2) for each fossil- or nuclear-fueled steam electric generating unit for which the plant has performed at least one cleaningoperation on metal process equipment since January 1,2000. See Part A Section 8 for unit classifications. Enter the steam electric generating unit ID under the section heading above (use steam electric generating unit IDs assigned in Table A-8). Make a copy of Section 2 foreach steam electric generating unit identified in TableA-8 using the "Copy Section 2" button below. Please provide all free response answers in the highlighted yellow areas.NOTE: Combined cycle systems are considered steam electric generating units and, therefore, any cleaning operations performed on ANY portion of a combined cycle system, including cleaning operationsassociated with the combustion turbine portion of the system should be reported in this part.

Thecitric acidis 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 thesecond stage anhydrous ammonia is added to raise the pH ofthe cleaning solution between 9 and 10 and air is bubbled through thesolution 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 thesteam electricgenerating unit, which is identified in Tables E-1 andE-2 of Section 2.
