Processing calendaring

Paper may also be colored by surface appHcation of dyestuff solutions after the paper has been formed and dried or partially dried by utilizing size-press addition, calendar staining, or coating operations on the paper machine. In addition, paper may be colored in off-machine processes by dip dyeings or absorption of dyestuff solution and subsequent drying, such as for decorative crepe papers. 

The facility manufactured (defined to include imported), processed, or otherwise used any listed chemical in quantities equal to orgreaterthan the established threshold in the course of a calendar year. 

Did your facility manufacture or process more than 25,000 pounds of the chemical In the calendar year ... 

If the processing or otherwise use of similar articles results in a total release of less than 0.5 pound of a toxic chemical in a calendar year to any environmental media, EPA will allow this release quantity to be rounded to zero and the manufactured items remain exempt as articles. EPA requires facilties to round off and report all estimates to the nearest whole number. The 0.5 pound limit does not apply to each individual article, but applies to the sum of all releases from processing or use of like articles. 

Table II (see pages 40-48) contains the list of individual chemicals and categories of chemicals subject to 1988 calendar year reporting. Some of the chemicals listed in Table II have parenthetic qualifiers listed next to them. A chemical that is listed without a qualifier is subject to reporting in all forms in which it is manufactured, processed, and used.

Also note that threshold determinations are based upon the actual amounts of a chemical manufactured, processed, or used over the course of the calendar year. The threshold determination may not relate to the amount of a toxic chemical brought on-site during the calendar year. For example, a stockpile of 100,000 pounds of a toxic chemical is present onsite but only 20,000 pounds is applied to a process Therefore, only the 20,000paunds processed is counted toward a threshold determination, not the entire 100,000 pounds of the stockpile... 

Indicate whether the chemical is manufactured (including imported), processed, or othen/vise used at the facility and the general nature of such activities and uses at the facility during the calendar year. Report activities that take place only at your facility, not activities that take place at other facilities involving your products. You must check all the blocks in this section that apply, tf you are a manufacturer of the chemical, you must check a and/or b, and at least one of c,.ji. e> orf. Refer to the definitions of manufacture," "process," and othenwise use" in the general information section of these instrilctions or section 372.3 of the rule for additional explanations. 

Note that total annual releases of less than 0.5 pounds from the processing or otherwise use of an article maintains the article status of that item. Thus, if the only releases you have are from processing an article, and such releases are less than 0.5 pounds per year, you are not required to submit a report for that chemical. The 0.5 pound release determination does not apply to just a single article, ft applies to the cumulative releases from the processing or use of that same typ>e of article (e.g., sheet metal or plastic film) that occurs over the course of the calendar year. 

To determine whether you are required to report under section 313, you must ascertain whetherthe total quantity of any listed chemical orchemical compound manufactured, processed, or used at your facility over the course of the calendar year exceeds any applicable threshold. For the facility described above, determination of reporting requirement would proceed as follows. (Note In determining eligibility, you will generate Information you need to complete several portions of the form.)... 

Missing or incorrect reporting year. The reporting year is the calendar year during which the reported data were collected it is not the year in which the Form R is sent to EPA. Form Rs are due to EPA on July 1, 1990 for chemicals manufactured, processed or othen/vise used... 

Facility-specific system including modules for air emissions, calendar, facility and agency processes, groundwater, hazardous waste, incident response, permit tracking, solid (non-hazardous) waste, work orders, and wastewater. 

Figure 3. 2-D SAXS scattering patterns of (a) as-received Nafion, showing a slight morphological anisotropy in the ionic domains from the membrane calendaring process, and (b) uniaxially oriented Nafion (Ab = 5.4).

Initial inspection of Figure 10.1 showed what appears to be a cyclical pattern in the clearings and issues. This was confirmed by the statistical process control charts in Figures 10.2-10.4. The broad peaks and valleys in Figure 10.1 seem to repeat every 20 to 25 days. At first, this seemed to be a strange number of days for a cycle - a monthly cycle of 30 or 31 days would have made more sense to some of us. However, the student was quick to point out that the average business month has between 21 and 22 days (365.25 calendar days per year) x (5 business days per week) / (7 calendar days per week) = 260.89 business days per year which, when divided by 12 months, is 21.75 or approximately 22 business days per month. 

Estimated releases of 2 poimds (0.9 kg) of 3,3 -dichlorobenzidine to the atmosphere from one facility in 1996, accoimted for 100% of the estimated total environment releases (TR196 1998). These releases are summarized in Table 5-1. The TRl data should be used with caution because only certain types of facilities are required to report information to the Toxics Release Inventory only if they employ more than 10 full-time employees, if their facility is classified rmder Standard Industrial Classification (SIC) codes 20 through 39, and if their facility produces, imports, or processes 25,000 or more pounds of any TRl chemical or otherwise used more than 10,000 pounds of a TRl chemical in a calendar year (EPA 1997). 

The other commercialized pentane isomerization process is that of the Standard Oil Co. (Indiana) (20). This process differs from the Indiana-Texas butane process in that the aluminum chloride is introduced as a slurry directly to the reactor and that about 0.5% by volume of benzene is added continuously in the feed to suppress side reactions. Temperature, catalyst composition, space velocity, and hydrogen chloride concentration are generally similar to those in the corresponding butane process, but the reactor pressure is about 100 pounds lower. The Pan American Refining Co. operated the Indiana pentane isomerization process commercially during the last nine months of the war and produced about 400 barrels of isopentane per calendar day.
