PART E. WASTES FROM CLEANING METAL PROCESS EQUIPMENT

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.
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.

Part: E
Section Title: 1. Metal Cleaning Operations
Instructions: 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.

Section Title: 2. Generating Unit Cleaning Data
Instructions: 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 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 for
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 cycle system, including cleaning operations
associated with the combustion turbine portion of the system should be reported in this part. When responding to these questions, provide answers that describe the typical cleaning operation for the steam
electric generating unit.

Copy Section 2
CBI?
Yes

E2-1. 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 fossil- or nuclear-fueled steam electric
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 which the plant performs a cleaning operation
on metal process equipment.

Yes

E3-1. 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. An
example is provided below.
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.
