### INSTRUCTIONS FOR MANUFA CTURER’S REPORT FORM

PRELIMINARY ASSESSMENT INFORMATION

What chemicals to report – This form applies to substances that are listed in 40 CFR 712.30.

Do not report on listed chemical s ubstances if these are manufactur ed or imported incidentally as a byproduct, non-isolated intermediate, or impurity.

A byproduct or co-product must be reported if it' s marketed or used as a subject (listed)

chemical.

Do not report a listed chemical substance if it is a component of a mixture (imported or manufactured). Note, though, that the mixture itself may be liste d as a reportable substance. Reporting is required, however, if the chemical is manufactured separa tely by a given company,

and then blended into a mixture. In such a cas e, the blending step(s) would be reported as processing activities. Reporting is al so required if the manufactured or imported chemical is (1) in aqueous solution; (2) in a solution containi ng an additive (such as a stabilizer or other chemical) to maintain the integrity or physical form of the substance; or (3) present in any grade or purity.

Reporting Period – Enter the months and years beginni ng and ending the 12-month period for which you report (e.g., July 81 - June 82). This reporting period is liste d with the chemical

substance in 40 CFR 712.30.

Who must report – Manufacturers and importers mu st report. See 40 CFR 712.25 for exemptions from reporting. In addition to th e actual synthesis of a compound, all refining, extracting, and purifying activities of a listed chemical subs tance are considered manufacturing

activities under Secti on 3(7) of TSCA (15 U.S.C. 2602(7 )). Reporting is required for all companies involved in any of these activities.

Repackaging is considered a processing activity and should not be reported as manufacture. A company that only repackages a listed chemical s ubstance is considered only a processor. Note, however, that if the company imports the chemi cal prior to repackagi ng it is considered a manufacturer and must report.

How many forms to complete – For each chemical, complete a separate form for each plant site

that manufactured the chemical.

If a site manufactured and imported the chemical , report both manufacture and import data on a single form.

A company that imported the chem ical, but did not process the imported quantity or manufacture an additional quantity, may submit a separate form for each import site or may submit a single form with the total data for all import sites.

Who may submit forms – Companies may choose to complete and submit forms to EPA from each plant site directly, or through company headquarters.

EPA Form 7710-35 (01/2005) Page 1 of 10Retention of forms – You should keep a copy of each completed form. Refer to the preprinted Control Number (shown in the upp er right corner on the front of the form) when communicating

EPA Form 7710-35 (01/2005) Page 3 of 10IV. PRELIMINARY ASSESSMENT INFORMATION

TSCA Regulable Quantities – Except under items 4 and 5, do not report any quantity of chemical substance that is manufactured or proce ssed solely for use as: a pesticide; tobacco or any tobacco product; any source material, specia l nuclear material, or byproduct material (as terms defined in the Atomic Energy Act of 1954 and regulations issued under such Act); firearms or ammunition; or food, food additives, drug, cosmetic, or device (as such terms are defined in section 201 of the Federal Food, Drug and Cosmetic Act). The above are not TSCA regulable.

Some of the chemical substances are manuf actured for both TSCA and non-TSCA regulable purposes. If a chemical from a given manufactur ing stream is solely for a non-TSCA use, no reporting is required. However, if a company produces a chemical from the same stream that will be used for both TSCA and non-TSCA purposes , the total quantity must be reported under items 4 and 5. Note that the quantity produced fo r TSCA purposes only is entered under item 2.

PART A: PLANT SITE ACTIVITIES

Accuracy – For each item, provide numbers that repres ent your best estimates based on readily

obtainable data.

Item 1 – Enter the total quantity of the chemical s ubstance imported in bulk during the reporting period. For a given compound, if a company is not involved in any manufacturing activity, and imports a chemical at one site and processes it at another facility, answer s need to be provided only for item 1 and items 9 through 11 (Part B). Note that the transfer of chemical to another site of the same company for processing is tr eated as if it were a customer use.

Item 2 – Enter the total quant ity of chemical domestically ma nufactured for TSCA use during the reporting period, not counting the losses report ed in item 3.

Item 3a–3d – In 3a, report the total quantity lost in manufacture of the substance during the reporting period. Report only routine losses. Do not report unusual spills or accidents. In calculating estimates for quantities not recovered you may: (1) use measured losses, if available,

or emission factors and other calcul ated releases from individual s ources; or (2) if these are not available, or only account for a portion of the total loss, you may make a simple mass balance estimate of the expected yield mi nus actual yield, where actual yiel d is the value reported in item 2. This quantity in 3a should then be broken down into three categories below (i.e., 3b + 3c + 3d = 3a). Specify the accuracy you report for 3b, 3c, and 3d, e.g., 1000 kg ± 30%.

3b. Quantity lost to the environment – This covers fugitive emissions to the atmosphere

and other losses not de scribed in 3c and 3d.

3c. Quantity in wastes trea ted to destroy the chemical.

EPA Form 7710-35 (01/2005) Page 4 of 103d. Quantity in wastes not trea ted to destroy the chemical – This includes, for example, any quantity disposed of in a landfill, surface impoundment, municipal sewage, or

storage.

Items 4–7 – Items 4–7 in part A require you to descri be the manufacturing process and your use

of the chemical in terms of the number of work ers and quantity of substance associated with three process categories. Three process categorie s are described below, followed by instructions for calculating quantities, worker-hours, and nu mber of workers. Additional instructions concerning items 4 through 7 are also listed.

PROCESS CATEGORIES

Enclosed Process – The process is designed an d operated so that there is no intentional release of the chemical. In this process category, only f ugitive or inadvertent releases occur and special measures are taken to prevent worker exposur e and environmental contamination. “Special measures” refer to procedures and equipment th at are monitored and used to prevent worker exposure, and scrubbers and other recovery equipment employed to prevent environmental release. Equipment with emergency pressure re lief venting would be allowed in this category; routine venting would not. With regard to handling the manufactured chemical, persons who handle closed packages containing the material would be counted under “enclosed process.” Person who package or transfer the unpackaged chemical woul d be counted in one of the following categories.

Controlled Release Process – The process is operated in a co ntrolled manner to minimize the release of the chemical into the workplace. Rele ase should generally be w ithin prescribed limits. These limits may be dictated by government regul ations or by company guidelines. If the chemical is vented outside the pl ant, the process is a “controlled release” process. Do not count general space ventilation fans.

Open Process – The chemical is routinely in direct c ontact with the atmosphere (workplace or outside the plant) and no measures are taken to prevent release. Routine direct contact would be associated, for example, with reaction vessels that are open vats, the tran sport or storage of the chemical in open containers (even in an othe rwise enclosed process) , and the venting of a chemical freely into the workplace atmosphere.

QUANTITIES

Process Category – Enter the greatest quantity that is pr ocessed in each process category. If there is more than one process stream, calculate each stream separately a nd then add the values for each process category. If a quantity of the ch emical passes in a series through an enclosed process and then passes through an open process, the same quantity would be reported twice, once under each process category. (The sum of thes e quantities may be greater than 100% of the total quantity manufactured.)

EPA Form 7710-35 (01/2005) Page 5 of 10Example 1 – A company manufactures technical grade chemical x in four steps.

350,000 kg—— ▸ 350,000 kg—— ▸ 350,000 kg—— ▸ 200,000 kg Open Enclosed Open Enclosed

The company would report: Enclosed 350,000 kg

Controlled release 0 Open 350,000 kg

Example 2 – A company produces the same chemical in a reagent and techni cal grade with the following steps.

Technical Grade Process:

350,000 kg—— ▸ 350,000 kg—— ▸ 350,000 kg—— ▸ 200,000 kg Open Enclosed Open Enclosed

Reagent Grade Process:

650,000 kg—— ▸ 500,000 kg—— ▸ 500,000 kg—— ▸ 400,000 kg Controlled Controlled Open Open

Release Release

The company would report: Enclosed 350,000 kg Controlled release 650,000 kg Open 850,000 kg

(The open process amount is the total of the maximum quantity in the open process category from each grade.)

Total Quantity – For items 5, 6, and 7, enter the tota l quantity processed in all process categories. (This total may be less than the sum of the quantities reported n the individual process categories.)

WORKER-HOURS

Worker-hours may be calculated for a given process category by multiplying the average number of full-time employees needed for the operati on by the number of hours operating annually. Alternatively, worker-hour information may be taken from preexisting in formation source such as resource planning or budget figures.

WORKERS

Report the total number of workers for each proce ss category. Workers are counted in a process category if (1) they are directly involved in manufacturing, processing, and handling the chemical during the reporting peri od or (2) they are regularly a ssigned maintenance or inspection

EPA Form 7710-35 (01/2005) Page 6 of 10personnel who work with the process from a re mote control room, and who do not regularly come in contact with the actual chemical stream, are not to be counted unless their exposure to the chemical stream is greater than or equa l to that of regularly assigned inspection and maintenance workers. If only control room work ers are associated with a process, and their exposure to the chemical stream is less than that of regularly assigned inspection and maintenance workers, the company must nevert heless report the process categories associated

with the manufacture and on-site use of the ch emical (column 3 in items 4 through 7). The

number of workers and total worker- hours however may be listed as zero.

Three process categories are described in the fo rm: enclosed, controlled release, and open. A worker should be counted as working with onl y one process category. If he operates several process types, count him under the one with which he spends the most time. If he spends an equal amount of time with several, c ount him under the most open process.

Example 3 – A company manufactured 1,000,000 kg of a chemical substance in 1980. It

manufactured the chemical for all twelve months of the year and did so in an enclosed process.

In order to run the production lin e, ten (10) workers were pres ent working 40 hour weeks; thus over the course of the year 20,800 worker-hours were used to run the production line.

Over the course of the year, twelve (12) di fferent workers worked on the production of the

chemical.

The form would then be filled out as follows:

Process category Quantity (kg) Worker-hours Total workers

Open

Controlled release

Enclosed 0

0 1,000,000 kg 0

Example 4 – A company manufactured 1,000,000 kg of a chemical substance in 1980. It manufactured the chemical for the entire year in a 24 hour/day process co nsisting of three steps in the open, controlled release, and open proce ss categories. The produc tion line was shut down

for maintenance for 2 weeks of th e years. The production line had three 8-hour shifts. Each shift in step 1 required 5 workers, while 7 and 10 wo rkers were needed per shift in steps 2 and 3, respectively. The total worker-hou rs required for each step follows:

Process category (Shifts/day x hours/shift x workers x days/week x weeks/year) Workers-hours

Open (Step 1) Controlled (step 2) Open (step 3) (3 x8 x 5 x7 x 50) (3 x8 x 7 x7 x 50) (3 x8 x 10 x7 x 50) 42,000 58,800 84,000

EPA Form 7710-35 (01/2005) Page 7 of 10Analysis of the personnel records showed that a total of 75 individuals worked on the production of the chemical during 1980. After examining th e personnel records, the company was able to fill in the following table:

Process category Total workers

Open (Step 1) Controlled (step 2) Open (step 3) 21

19

35

75

Note that some workers are not double counted or “split” even though some jobs may require moving from one step of the process to another st ep of the same process. An employee working on both step 1 and step 2 is counted only in step 1 if he/she spends most of his time at that step. After adding together steps in the same pro cess category, the company would report as follows:

Process category Quantity (kg) Worker-hours Total workers

Enclosed 1,000,000 kg 1,000,000 kg

0 126,000 58,800

Item 4 – This item applies to the ma nufacture of the chemical substa nce and includes all steps to ready the chemical for fu rther processing or use.

Item 5 – This item applies to the use of the chemical at your plant site as a reactant in the manufacture of another chemical substance, wher e the molecular structure of the chemical is altered by breaking chemical bonds or making new chemical bonds between the original substance and some other substance. Report on all processing up to and including the actual reaction step and any ancillary steps which recy cle unreacted chemicals back to the reactor vessel. Do not report on subse quent activities in this question.

Item 6 – Report the quantity of the chemical substance that you use on site. Examples include cleaning solvents, dielectric fluids, emulsifiers, and lubricants. Do not report any quantity that you react to make a product.

Item 7 – Report the quantity of the chemical substance that you process at the manufacturing site into products for on site use or sa le. (Note that this does not in clude manufacture of the chemical substance; this is reported in item 4 above.) Th is items does not include the quantity of chemical substance that you incorpor ate into a mixture or article. Report the steps up to and including incorporation of the chemical into an article; do not include any further pr ocessing of the article.

Item 8 – Report the quantity of the chemical substance that you prepare for commercial distribution in each of the product types in 8a to 8g. Do not include any quantity of chemical substance that your customers will further pr ocess. This will be reported in item 9.

In items 8a to 8f, report the quantity of the chem ical substance in products that are for domestic use. If you are uncertain about whether your pr oducts are for domestic or foreign use, report

them as domestic.

EPA Form 7710-35 (01/2005) Page 8 of 10The products are divided into industrial a nd consumer products. “Industrial” means the manufacturing and service industries covered by the North American Industry Classification System codes. Products meant to be used prim arily by the general popula tion are considered to be “consumer” products. The following definition from the Consumer Product Safety Act can be used as a guide (15 U.S.C. 2052(a)(1)): “The te rm ‘consumer product’ means any article, or component part thereof, produced or distributed (i) for sale to a consumer for use in or around a permanent or temporary household or residence, a school, in recreation, or ot herwise, or (ii) for the personal use consumption or enjoyment of a consumer in or around a permanent or temporary household or residence, a school, in recreation, or othe rwise.” If you are uncertain about whether your products are industrial or consumer, report them as consumer.

Three types of industrial and consumer product types are described below.

“Chemical substance or mixture” means a chemical, or mixture containing the chemical, that is used directly by the persons using the product, e.g., cleaner s, paints, inks, deodorizers, solvents, etc. This includes chemicals or mixtur es in containers or other articles whose purpose is to release the chemical (e.g., cans of spra y paint, ink pens, and other applicators).

“Articles or products with no release” are articles constructed to prevent human exposure to or

release to the environment of the chemical substance during normal use and storage (e.g., chemical coatings on internal components, a nd chemicals inside sealed articles as in thermometers and batteries).

“Articles or products with some release” are articles whose materi al components are made of chemicals which come in direct contact with pe rsons using the article, the atmosphere, land or water; e.g., exposure can come from leaching eva poration, or surface contact. This includes such articles as plastic containers, chemically treated te xtiles, printed paper, coat ed appliances, etc. If

the chemical itself is sold in a bottle or othe r container it should be reported under “Chemical substance or mixture,” not as an article. Only the container itself is an article for purposes of this form; the substance it contains is not a component of an article.

In item 8g, report the quantity of chemical substance that you export directly either as the

chemical or contained in mixtures or articles.

Item 9 – Estimate the quantity of the chemical substa nce that your customers process for each of the uses listed in items 9a to 9h. (Do not include the quantity of chemical substances that your customers will use without further processing; that quantity should be reported in item 8a or 8d.)

For items 9a to 9g, follow the same directions as for 8a to 8g.

For item 9h, report the quantity of chemical s ubstance for which your customers’ uses are

unknown.

Report your best estimate for items 9a to 9h within ± 50%. If you cannot estimate an item to this degree of accuracy, include the quantity in item 9i. You may report “unknown” if the data would reveal information subject to a c onfidentiality agreemen t between you and your

customers.

EPA Form 7710-35 (01/2005) Page 9 of 10Item 10 – If you report your customers’ uses as unknow n (item 9i above) for more than 20% of the total quantity that you manufacture and import (items 1 and 2 above) list the names under which you distribute the chemical substance.

This item will allow EPA, if necessary, to find out about the chemical uses you have reported as “unknown” by requiring processors of your products to report directly to us.

Item 11 – This item addresses your general knowledge of the pro cess types your customers use to process the chemical. Estimate the quantity of the chemical that your customers process in each of the three process categories. Specify “unknown” if you do not know to within ± 50%.
