PART E. WASTES FROM CLEANING METAL PROCESS EQUIPMENT

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: When 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.

wastes at the plant. Metal cleaning wastes include any process wastewaters resulting from clecleaning compounds] any metal process equipment, including, but not limited to, boiler tube cle

and air heater cleaning. This part also collects information on combined cycle combustion turbiand soot blowing. For Part E of the questionnaire, report all soot blowing operations that use wacleaning event. Has the plant generated any wastes from cleaning metal process equipment associated with fo

In Table E-1, provide information about a typical cleaning event for each type of cleaning operation that uses chemical compounds on metal process equipment associated with 

generating units. In addition, please note whether or not 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 won 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 cleaning operation 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 each steam electric generating unit identified in Table A-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 cyassociated with the combustion turbine portion of the system should be reported in this part. When responding to these questions, provide answers that describe telectric generating unit.
