routes of exposure to the substance. (vii) Precautionary

measures to control worker exposure and/or environmental release identified in subpart E of this part for the substance, or alternative control measures which EPA has determined under Sec. 721.30 provide substantially the same degree of prot ection as the

identified control measures. (viii) Any generally applicable precautions for safe handling and use of the substance which are known to the employer, including appropriate hy gienic practices, protective measures during repair and maintenan ce of contaminated equipment, and procedures for response to spills and

leaks. (ix) Any generall y applicable control measures which are known to the employer, such as appropriate engineering controls, work practices, or personal protective equipment. (x) Emergency

first aid procedures known to the employ er. (xi) The date of preparation of the MSDS or of its last revision. (xii) The name, address, and telephone number of the individual preparing or distributing the MSDS, or a responsible par ty who can provide additional information on the substance for hazard evaluation and any appropriate emergency

procedures. (3) If no relevant information is found or known for an y given category on the MSDS, the employ er must mark the MSDS to indicate that no applicable information was found. (4) Where multiple mixtures containing the substance have similar compositions (i.e., the chemical ingredients are essentially the same, but the specific composition varies from mixture to mixture) and similar hazards, the emplo yer may prepare one MSDS to apply to all of these multiple mixtures. (5) If the employ er becomes aware of any significant new information regarding the hazards of the substance or way s to protect against the hazards, this new informat ion must be added to19

the MSDS within 3 months from the time the employ er becomes aware of the new information.

If the substance is not currentl y being manufactured, imported, processed, or used in the employ er's workplace, the employ er must add the new inf ormation to the MSDS before the substance is reintroduced into the workplace. (6) The emplo ye r must ensure that persons receiving the substance from the employ er are provided an appropriate MSDS with their initial shipment and with the first shipment a fter an MSDS is revised. The employ er may either provide the MSDS with the shipped containers or send it to the person prior to or at the time of shipment. (7) The emplo ye r must maintain a cop y of the MSDS in its workplace, and must ensure that it

is r eadily accessible during each work shift to employ ees when they are in their work areas. (8) The MSDS may

be kept in any

form, including as operating procedures, and may be designed to cover groups of substances in a work area where it may be more appr opriate to address the potential hazards of a process rather than individual substances. However, in all cases, the required information must be provided for each substance and must be readil y accessible during each work shift to employ ees when they are in their work areas. (9) The MSDS must be printed in English; however, the information may be repeated in other languages. (d) Employ ee information and training. Each employ er must ensure that employ ees are provided with information and training on t he substance identified in subpart E of this part. This information and training must be provided at the time of each emplo yee's initial assignment to a work area containing the substance and whenever the substance subject to this section is

EPA will inform submitters of the disposition of such r equests in writing, and will explain the reasons

therefor e when they

are denied.26

(c) An y predictable or purposeful release of a use stream containing the substance associated with any use of the substance from any site: (1) Into the waters of the U nited States. (2) Into the waters of the United States without application of one or more of the following treatment technologies as specified in subpart E of this part either b y the discharger or, in the case of a release through publicly

EPA will review and act on written requests to approve monitoring procedures or alternative calcu lations within 90 day s after such requests are received. EPA will inform submitters of the disposition of such requests in writing, and will explain the reasons therefore when they are denied.

Sec. 721.91 Computation of estimated surface water concentra tions:

In structions. These instructions describe the use of the equation specified in Sec. 721.90(a)(4) and (b)(4) to compute estimated surface water concentrations which will result from release of a substance identified in subpart E of thi s part. The equation shall be computed for each site using the stream flow rate appropriate for the site according to paragraph (b) of this section, and the highest number of kilograms calculated to be released for that site on a given day according to par agraph (a) of this section. Two variables shall be considered in computing the equation, the number of kilograms released, and receiving stream flow. (a) Number of kilograms released. (1) To calculate the number of kilograms of substance to be

released from manufacturing, processing, or use operations, as specified in the numerator of the equation, develop a process description diagram which describes each manufacturing, processing, or use operation involving the substance. The process description must include the major unit operation steps and chemical conversions. A unit operation is a functional step in a manufacturing, processing, or use operation where substances undergo chemical changes and/or27

changes in location, temperature, pressure, ph ys ical st ate, or similar characteristics. Include steps in which the substance is formulated into mixtures, suspensions, solutions, etc. (2) Indicate on each diagram the entry point of all feedstocks (e.g., reactants, solvents, and

catal ys ts) used in the operat ion. Identify each feedstock and specify its approximate weight regardless of whether the process is continuous or batch. (3) Identify

all release points from which the substance or wastes containing the substance will be released into air, land, or wa ter. Indicate these release points on the diagram. Do not include accidental releases or fugitive emissions. (4) For releases identified in the diagram that are destined for water, estimate the amount of

substance that will be released before the subst ance enters control technology . The kilograms of substance released may

be estimated based on: (i) The mass balance of the operation, i.e., totaling inputs and outputs, including wastes for each part of the process such that outputs equal inputs. The a mount released to water may be the difference between the amount of the substance in the starting material (or formed in a reaction) minus the amount of waste material removed from each part of the process and not released to

water and the amount of the su bstance in the final product. (ii) Phy sical properties such as water solubility where a known volume of water being discharged is assumed to contain the substance at concentrations equal to its solubility in water. This approach is particularly useful where the waste stream results from separation of organic/water phases or filtration of the substance from an aqueous stream to be discharged. (iii) Measurements of flow rates of the process/use stream and known concentrations of the

substance in the stream. (5) After releases of a substance to water are estimated for each operation on a site, total the

releases of the substance to water from all operations at that site. The value (number of kilograms) specified in the numerator of the equation should reflect total kilograms of substance released to water per day from all operations at a single site. (6) Use the highest expected dail y release of the substance for each site. (b) Receiving stream flow. (1) The receiving stream flow shall be expressed in million liters per day (MLD). The flow rate data to be used must be for the point of release on the water body

that first receives re lease of the substance whether by direct discharge from a site, or by indirect discharge through a Publicly

- Owned Treatment Works (POTW) for each site. The flow rate reported shall be the lowest 7

- day average stream flow with a recurrence interval of 10 ye ars (7

- Q

- 10). If the 7

- Q

- 10 flow rate is not available for the actual point of release, the stream flow rate should be used from the U.S. Geological Survey (USGS) gauging station that is nearest the point of release that is expected to have a flow rate les s than or equal to the receiving stream flow at the point of release. (2) Receiving stream flow data may be available from the National Pollutant Discharge Elimination Sy stem (NPDES) permit for the site or the POTW releasing the substance to surface

wa ter, from the NPDES permit

- writing authority for the site or the POTW, or from USGS publications, such as the water

- data report series. (3) If receiving stream flow data are not available for a stream, either the value of 10 MLD or the daily flow of wa stewater from the site or the POTW releasing the substance must be used as an assumed minimum stream flow. Similarly , if stream flow data are not available because the location of the point of release of the substance to surface water is a lake, estuary , b ay , or ocean, then the flow rate to be used must be the daily flow of wastewater from the site or the POTW28

releasing the substance to surface water. Wastewater flow data may be available from the NPDES permit or NPDES authority for the site or the POTW rel easing the substance to water.

(4) EPA will issue significa nt new use rules under this section by one of the following three processes: direct final rulemaking, interim final rulemaking, or notice and comment rulemaking. EPA will use the direct final rulemaking process to issue significant new use rules unless it determines that, in a particular case, one of the other processes is more appropriate. (i)(A) When EPA uses the direct final rulemaking procedure to issue a significant new use rule

it will issue a direct final rule in the final rule section of the Fed eral Register following its

d ecision to develop a significant new use rule under this section for a specific new chemical

substance. (B) The Federal Register document will state that, unless written notice is received by EPA

w ithin 30 day s after the da te of publication that someone wishes to submit adverse or critical comments, the SNUR will be effective 60 day s from date of publication. The written notice of intent to submit adverse or critical comments should state which SNUR(s) will be the subject of the adverse or critical comments, if several SNURs are established through the direct final rule. If notice is received within 30 day s after the date of publication that someone wishes to submit adverse or critical comments, the section(s) of the direct f inal rule containing the SNUR(s) for

which a notice of intent to comment was received will be withdrawn b y EPA issuing a document in the final rule section of the Federal Register, and EPA will issue a proposed rule in the proposed rule section of the Fede ral Register. The proposed rule will establish a 30

- day comment period. (C) If EPA, having considered an y timel y comments submitted in response to the proposal, decides to establish notification requirements under this section, EPA will issue a final r ule adding the substance to subpart E of this part and designating the significant new uses subject to
