Persons wishing to receive confirmation of receipt of their comments should include a self-addressed stamped postcard. Internet users may access all comments received by the Department of Transportation at http://dms.dot.gov.

The following is a section-by-section summary of the proposed changes.

Section-by-Section Review

Part 171

Section 171.7

Based on a petition for rulemaking by the Organic Peroxide Producers Safety Division (OPPSD) (P-1429), we are proposing to incorporate by reference a document entitled “An Example of a Test Method for Vent Sizing—OPPSD/SPI Methodology” published in the American Institute of Chemical Engineers, Process Safety Progress Journal, June 2002, issue (Vol. 21, No. 2). The document describes an alternative method to determine the size of emergency relief devices on portable tanks transporting organic peroxides.

We are proposing to remove the American Society for Testing and Materials ASTM A 607-98 “Standard Specification for Steel, Sheet and Strip, High-Strength, Low-Alloy, Columbium or Vanadium, or Both, Hot-Rolled and Cold-Rolled.” We are proposing to incorporate by reference the ASTM A 1008/A 1008M-3 “Standard Specification for Steel, Sheet, Cold-Rolled, Carbon, Structural, High-Strength Low-Alloy and High Strength Low-Alloy with Improved Formability” and A 1011/A 1011M-03a “Standard Specification for Steel, Sheet and Strip, Hot-Rolled, Carbon, Structural, High-Strength Low-Alloy and High Strength Low-Alloy with Improved Formability.” In 2000, ASTM A 607-98 was replaced by ASTM A 1008/A 1008M-03 and A 1011/A 1011M-03a.

We are also proposing to incorporate by reference the Department of Defense's (DOD) “Packaging of Hazardous Material, DLAD 4145.41/AR 700-143/ AFJI 24-210/NAVSUPINST 4030.55B/ MCO 4030.40B”. See § 173.7 preamble discussion.

Also, we are proposing to update the following documents which are incorporated by reference:

—Chlorine Institute instruction booklets entitled “Chlorine Institute Emergency Kit ‘A’ for 100-lb. & 150-lb. Chlorine Cylinders” (2000 edition) and “Chlorine Institute Emergency Kit ‘B’ for Chlorine Ton Containers” (1996 edition) to the 2003 edition; and

—Transport Canada Transportation of Dangerous Goods Regulations from the July 1985 edition to the August 2001 edition.

In paragraph (b), we are proposing to remove the table entry “National Association of Corrosive Engineers (NACE)” and NACE Standard TM090969 which describes an acceptable test for a liquid corrosive material. We failed to remove this entry when we revised the definition and testing methods for corrosive materials in a previous rulemaking.

Section 171.8

We are proposing to revise the definition for “Materials of trade” (MOTS) by removing the phrase “in direct support of a principal business that is other than transportation by motor vehicle.” This amendment will clarify that hazardous materials being transported for private carriage may be transported under the MOTS exception, if qualified, regardless of the principal business of the carrier.

Section 171.12a

In paragraph (b)(2), we propose to clarify that certain exceptions in Transport Canada's Transportation of Dangerous Goods (TDG) Regulations are not recognized under the reciprocity provisions; specifically, materials subject to the 500 kg exception in paragraph 1.16 of the TDG Regulations, may not be transported under the provisions of § 171.12a and are subject to the requirements of the HMR.

Section 171.14

Currently paragraph (d)(3) authorizes use of the KEEP AWAY FROM FOOD label and placard in effect on September 30, 1999, until October 1, 2003. Since the transition period has expired, we are proposing to remove paragraph (d)(3).

Part 172

Section 172.101

Currently, use of specification 3T cylinders, which are bulk packagings, is authorized in the non-bulk packaging sections in column (8B) of the Hazardous Materials Table (HMT). We are proposing to add a statement in § 172.101(i)(3) and a new paragraph (i)(5) to clarify that some bulk packaging authorizations are found in column (8B) of the HMT and in special provisions in column (7).

In the current HMT, “Bromine” and “Bromine solutions” are combined into one entry. The entry has a “+” in column (1) which fixes the proper shipping name, hazard class, ID number and packing group. Bromine and bromine solutions are assigned to Class 8 (corrosive) and have a subsidiary poison inhalation hazard in Zone A. It has been brought to our attention that some bromine solutions do not meet the criteria for a PIH Zone A material and are, in fact, in Hazard Zone B. Under the current regulations, a bromine solution meeting the criteria for a PIH Zone B material must be packaged and offered for transportation in the same manner as a bromine solution meeting the criteria for a PIH Zone A material. We are proposing to revise the HMT by adding two new entries, one for bromine solution, PIH Zone A and one for bromine solution, PIH Zone B. In the new table entries, we are proposing to Start Printed Page 49848delete special provisions A3 and A6 in column (7) since bromine and bromine solutions are forbidden for transportation by air. Additionally, for each entry we are proposing to add missing stowage category “D” for vessel transportation in column 10A of the HMT. Stowage category “D” is described in § 172.101(k)(4).

In a final rule published on June 21, 2001 (HM-215D; 66 FR 33337), we removed the domestic entry “Denatured Alcohol, NA 1987” based on our determination that the entry “Alcohols, n.o.s., UN 1987” was equally appropriate. The Renewable Fuels Association (RFA) petitioned RSPA (P-1430) to reinstate the entry “Denatured Alcohol, NA 1987.” The petitioner states that based on the flashpoint of the material, some ethanol shippers are using the shipping description “Flammable liquid, n.o.s., UN 1993” rather than “Alcohol, n.o.s., UN 1987.” The RFA expressed concern for the safety of emergency responders. The Emergency Response Guidebook (ERG) directs emergency responders to Guide 128 for ID number 1993, and recommends “regular foam” to fight large fires. Guide 127 for ID number 1987 recommends “alcohol-resistant foam.” The RFA states that the entry “Denatured Alcohol, NA 1987” which corresponds to Guide 127 in the ERG is the more appropriate shipping description. Based on the petition, we are proposing to reinstate the entry. We are also proposing to add the new special provision for the entries “Denatured Alcohol, NA 1987” and “Alcohols, n.o.s., UN 1987” to allow solutions of alcohol and petroleum products be described as either “Denatured Alcohol” or “Alcohols, n.o.s.” provided the solution contains no more than 5% petroleum products.

We are proposing to correct an error in columns (9A) and (9B) for the entries “sec-Butyl chloroformate, NA 2742” and “Isobutyl chloroformate, NA 2742.” The current HMT reflects these material may be transported by air. These materials are poisonous by inhalation in Hazard Zone B and are forbidden on passenger and cargo only aircraft.

We are proposing to revise the entry for “Refrigerating machines, containing flammable, non-toxic, liquefied gas, UN 3358” by adding a reference to § 173.307 in column (8A) of the HMT. Section 173.307 excepts refrigerating machines containing 12 kg (25 pounds) or less of a flammable, non-toxic gas from the HMR, except when offered or transported by air or vessel. We are also proposing to correct inconsistencies with the International Maritime Dangerous Goods (IMDG) Code pertaining to vessel stowage for this entry.

We are proposing to revise the entry for “1,3,5-Trimethylbenzene, UN 2325” by adding a limited quantity exception for flammable liquids (see § 173.150) in Column (8A) of the HMT. This revision would be consistent with entries for other PG III flammable liquids in the HMR and in international regulations.

Section 172.102

We are proposing to revise Special provision 53 to provide relief from the subsidiary hazard class/division entry on the shipping paper if the material is excepted from the subsidiary label requirements.

Section 172.203

For readers' convenience, we are proposing to add a new paragraph (l)(4) which cross-references § 171.4. Section 171.4 excepts marine pollutants in non-bulk packagings from the HMR, except when transported by vessel.

Section 172.205

Section 172.205 prescribes shipping paper requirements for shipments of hazardous waste. Frequently, users of the HMR are not aware that the word “Waste” must precede the proper shipping name as provided by § 172.101(c)(9). We are proposing to add a new paragraph alerting the user to this requirement.

Section 172.504

In a final rule published on June 21, 2001 (HM-215D; 66 FR 33426), we authorized the display of only one placard bearing one compatibility letter when certain Class 1 materials of different compatibility groups are transported together in a single transport vehicle or container. We are proposing to amend § 172.504(g)(2) to clarify that explosives articles of compatibility groups C, D, or E when transported with explosives articles in compatibility group N may be placarded with a Class 1 compatibility group D placard.

Section 172.519

We are proposing to editorially revise paragraph (f) by adding the parenthetical phrase “(IBR, see § 171.7 of this subchapter),” after the wording “ICAO Technical Instructions, the IMDG Code, or the TDG Regulations”.

Part 173

Section 173.7

Currently, § 173.7 authorizes military shipments of hazardous materials if the materials are packaged in accordance with the HMR or in packagings of equal or greater strength and efficiency as certified by DOD in accordance with the procedures prescribed by “Performance Oriented Packagings of Hazardous Material, DLAR 4145.41/AR 700-143/AFR 71-5/NAVSUPINST 4030.55/MCO 4030.40.” The DOD has revised this document and renamed it “Packaging of Hazardous Material, DLAD 4145.41/AR 700-143/AFJI 24-210/NAVSUPINST 4030.55B/MCO 4030.40B.” In this NPRM, we are proposing to update the reference to the revised document.

Section 173.28

In paragraph (b)(3), we are proposing to clarify that packagings made of fiberboard are authorized for reuse.

Section 173.31

Since January 1, 1978, new non-pressure tank cars have had bottom outlet protection. To determine retrofit requirements, the FRA and the industry participated in a risk-analysis evaluation of the commodities carried in these cars. Those commodities requiring bottom outlet protection were listed in Appendix Y to the Tank Car Manual (AAR Manual of Standards and Recommended Practices,—1002). From time to time, additional commodities have been added. As far back as 1981, the risk-analysis evaluation has determined that molten sulfur does not require any retrofitted protection; consequently, it was not listed. Based on similar analysis, elevated temperature materials were not listed. Despite this, the regulations promulgated under a final rule published on September 21, 1995 ( HM-175A; 60 FR 49073), require retrofit by July 1, 2006, for all commodities not specifically listed in Appendix Y. In this NPRM we are proposing to lessen the burden on shippers of molten sulfur and elevated temperature materials by explicitly removing these commodities from the requirement to retrofit tank cars.

Section 173.150

Paragraph (f)(1) defines the term “combustible liquid” and states that a flammable liquid reclassed as “combustible liquid” may not be transported by air or vessel, except when other means of transportation is impracticable. Section 173.120 Class 3-Definitions, paragraph (b)(2), contains the same information. In this NPRM, we are proposing to remove paragraph (f)(1) to eliminate the redundancy.

Section 173.225

Currently, the Note to paragraph (e)(3)(vi) directs the reader to Appendix 5 of the UN Manual of Tests and Criteria Start Printed Page 49849for an example of a method to determine the size of emergency-relief devices. The American Institute of Chemical Engineers (AIChE), in a document published in the Process Safety Progress Journal (see § 171.7 preamble), describes an alternative method to determine the size of emergency-relief devices on portable tanks transporting organic peroxides. In this NPRM, we are proposing to also authorize this alternative method.

Section 173.241

For clarity, in paragraph (c), we are proposing to add a reference to certain additional requirements in § 176.340 that apply when offering combustible liquids in portable tanks for transportation by vessel.

Section 173.301

In paragraph (a)(9), we are proposing to revise the second sentence containing a requirement that the outside packaging must conform to the requirements in § 173.25. Because of their thin walls, size, or shape, 2P, 2Q, 3E, 3HT, spherical 4BA, 4D, 4DA, 4DS, and 39 cylinders must be offered in a combination packaging, where the cylinder is the inner packaging contained in a strong non-bulk outer packaging. In addition to the applicable marking and labeling requirements in subparts D and E, respectively, the outer packaging must be marked with an indication that the inner packagings conform to the applicable specifications. This change will remove the implication that the outer packaging is an overpack and, as such, each inner packaging must meet the applicable part 172 marking and labeling requirements.

In paragraph (l)(2), we are proposing to revise the wording to state clearly that foreign cylinders filled for export must be fitted with pressure relief devices when required by the HMR for the gas contained within the cylinder. In a final rule published on August 8, 2002 (HM-220D; 67 FR 51645), we revised the language stating that the cylinders must meet the specifically listed requirements “in addition to other requirements of this subchapter.” In removing the wording “in addition to other requirements of this subchapter,” we inadvertently overlooked that the wording included compliance with the pressure relief device requirements.

We are proposing to editorially revise paragraph (m) by adding the parenthetical phrase “(IBR, see § 171.7 of this subchapter)” after the first occurrence of the term “Canadian Transport of Dangerous Goods (TDG) Regulations.”

Section 173.302a

In paragraph (a), we are proposing a minor editorial change.

In paragraph (d), we are proposing to authorize use of a DOT 3AL1800 cylinder for the transportation of diborane and diborane mixtures.

We are proposing to add paragraph (e) to reinstate the requirement that a cylinder containing fluorine may not be charged to over 400 psig at 21 °C (70 °F) and may not contain more than 2.7 kg (6 lbs) of gas. It was brought to our attention that this requirement was removed in HM-220D and, for safety concerns, should be reinstated.

Section 173.304a

In the paragraph (a)(2) table, in column 3, we are proposing to remove several references to DOT specification 4, 4A, 9, 38, 40 and 41 cylinders. In a final rule published August 8, 2002 (HM-220D; 67 FR 51647) we discontinued authorization for the use of DOT 3C, 3D, 4, 4A, 4B240X, 4B240FLW, 4C, 9, 25, 26, 33, 38, 40 and 41 cylinders. Also, for the entry Bromotrifluoromethane, we propose to correct “DOT-3AL40” to read “DOT-3AL400” in column 3.

Sections 173.314 and 173.319

Currently the HMR require a shipper to notify the Bureau of Explosives (BOE) whenever a rail car containing a time-sensitive product is not received by the consignee within 20 days from shipment. We are proposing to revise the requirement to require notification to the appropriate office in the Federal Railroad Administration.

Section 173.315

We are proposing to revise the paragraph (a) table by adding a new Note 27 which authorizes the use of non-specification cargo tanks for the entry “Ammonia, anhydrous or Ammonia solutions, with greater than 50 percent ammonia.”

Section 173.337

In the introductory text, we are proposing to reinstate a requirement that a cylinder containing nitric oxide may be charged to a pressure of not more than 5,170 kPa (750 psig) at 21 °C (70 °F). It was brought to our attention that this requirement was inadvertently removed in HM-220D and, for safety concerns, should be reinstated.

Part 178

Sections 178.338-2 and 178.345-2

We are proposing to remove the reference to ASTM Standard A 607 and add ASTM Standards A 1008/A 1008M and A 1011/A 1011M in its place. See § 171.7 preamble discussion.

Section 178.606

In paragraph (c)(2), we are proposing to correct the formula for calculating the pressure to be applied when a packaging containing a solid is subjected to a dynamic compression test. The formula currently in the HMR is applicable to liquids.

Part 179

Section 179.200-7

We are proposing to amend paragraph (e) by adding a reference to § 171.7 for a standard that is incorporated by reference.

Part 180

Section 180.205

In paragraph (c)(2), we are proposing to add a reference to new § 180.212. See § 180.212 preamble discussion. Also, we are proposing to broaden the provisions in paragraph (I)(2) to allow a composite cylinder that is condemned to have the wording “CONDEMNED” displayed instead of stamped on the cylinder. The use of a label is currently authorized in some exemptions.

Section 180.212

The HMR authorize the repair of DOT 4-series cylinders, but not DOT 3-series cylinders. In this NPRM, we are proposing to allow repairs to a DOT 3-series cylinder under the terms of an approval issued by the Associate Administrator under subpart H of part 107. In addition, the person that performs the repair work must have an approval as currently required under subpart I of part 107.

Note in this regard, however, that certain repairs to cylinders will not require an approval. For example, an approval will not be required for the removal and replacement of non-pressure components on a DOT 3-series cylinder, such as a neck ring or foot ring; the replacement material must be equivalent to that used at the time of original manufacture. Such repairs were authorized in former § 173.34(h) of the HMR for DOT 3A, 3AA, 3B, and the obsolete 3C cylinder when performed by a manufacturer of these types of cylinders, tested and repaired under the supervision of an inspector, and reported in accordance with the original specification. We removed § 173.34(h) from the HMR in HM-220D. In this NPRM, we propose to add these requirements back into the regulations and also allow repairs to be made by a DOT authorized repair facility.Start Printed Page 49850

Additionally, no approval will be required for the repair of worn or damaged cylinder neck threads when performed by the original cylinder manufacturer in accordance with the cylinder's specification requirements and under the supervision of an independent inspection agency. CGA Pamphlets C-6 and C-6.1 contain guidelines for inspection of the cylinder neck areas for damaged threads. The cylinder must be rejected if the required number of effective threads are not engaged to provide a gas-tight seal. The rejected cylinder may qualify for repair to restore the effectiveness of the threads. If the threads cannot be repaired, the cylinder must be condemned. We proposed to update the reference to CGA Pamphlet C-6.1 from the 1995 to the 2002 edition in an NPRM published on September 10, 2003 (HM-220F; 68 FR 53318). The 2002 edition contains criteria for inspection of cylinder neck threads for abnormal thread conditions resulting from structural defects, corrosion, or damage. Currently CGA is updating CGA Pamphlet C-6 to better address inspection for neck areas on high pressure and low pressure steel cylinders. We will consider adopting the revised pamphlet in a future notice of proposed rulemaking.

Section 180.417

In paragraph (b)(2)(v), we are proposing to reinstate the requirement that each test or inspection report completed for a repaired cargo tank must include the ASME or National Board Certificate of Authorization number of the facility performing the repairs.

Regulatory Analyses and Notices

A. Executive Order 12866 and DOT Regulatory Policies and Procedures

This proposed rule is not considered a significant regulatory action under section 3(f) and was not reviewed by the Office of Management and Budget (OMB). The proposed rule is not considered a significant rule under the Regulatory Policies and Procedures order issued by the U.S. Department of Transportation (44 FR 11034). The costs and benefits of this proposed rule are considered to be so minimal as to not warrant preparation of a regulatory impact analysis or a regulatory evaluation.

In this notice, we propose to amend miscellaneous provisions in the HMR to clarify the provisions and to relax overly burdensome requirements. We are also responding to requests from industry associations to update and add references to standards that are incorporated in the HMR. These clarifications and updates of the HMR will enhance safety.

B. Executive Order 13132

This proposed rule was analyzed in accordance with the principles and criteria contained in Executive Order 13132 (“Federalism”). This proposed rule would preempt state, local and Indian tribe requirements but does not propose any regulation that has substantial direct effects on the states, the relationship between the national government and the states, or the distribution of power and responsibilities among the various levels of government. Therefore, the consultation and funding requirements of Executive Order 13132 do not apply.

Federal hazardous material transportation law, 49 U.S.C. 5125(b)(1), contains an express preemption provision (49 U.S.C. 5125(b)) preempting state, local, and Indian tribe requirements on certain covered subjects. Covered subjects are:

(i) The designation, description, and classification of hazardous materials;

(ii) The packing, repacking, handling, labeling, marking, and placarding of hazardous materials;

(iii) The preparation, execution, and use of shipping documents related to hazardous materials and requirements related to the number, content, and placement of those documents;

(iv) The written notification, recording, and reporting of the unintentional release in transportation of hazardous materials; or

(v) The design, manufacture, fabrication, marking, maintenance, reconditioning, repair, or testing of a packaging or container which is represented, marked, certified, or sold as qualified for use in the transport of hazardous materials.

This proposed rule concerns the classification, packaging, marking, labeling, and handling of hazardous materials, among other covered subjects. If adopted as final, this rule would preempt any State, local, or Indian tribe requirements concerning these subjects unless the non-Federal requirements are “substantively the same” (see 49 CFR 107.202(d)) as the Federal requirements.

Federal hazardous materials transportation law provides at 49 U.S.C. 5125(b)(2) that if RSPA issues a regulation concerning any of the covered subjects, RSPA must determine and publish in the Federal Register the effective date of Federal preemption. That effective date may not be earlier than the 90th day following the date of issuance of the final rule and not later than two years after the date of issuance. RSPA proposes the effective date of federal preemption be 90 days from publication of a final rule in this matter in the Federal Register.

C. Executive Order 13175

This proposed rule has been analyzed in accordance with the principles and criteria contained in Executive Order 13175 (“Consultation and Coordination with Indian Tribal Governments”). Because this proposed rule does not have tribal implications, does not impose substantial direct compliance costs on Indian tribal governments, and does not preempt tribal law, the funding and consultation requirements of Executive Order 13175 do not apply, and a tribal summary impact statement is not required.

D. Regulatory Flexibility Act, Executive Order 13272, and DOT Procedures and Policies

The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires an agency to review regulations to assess their impact on small entities. An agency must conduct a regulatory flexibility analysis unless it determines and certifies that a rule is not expected to have a significant impact on a substantial number of small entities. This proposed rule would amend miscellaneous provisions in the HMR to clarify provisions based on our own initiatives and also on petitions for rulemaking. While maintaining safety, it would relax certain requirements that are overly burdensome and would update references to consensus standards that are incorporated in the HMR. The proposed changes are generally intended to provide relief to shippers, carriers, and packaging manufacturers, including small entities.

This proposed rule has been developed in accordance with Executive Order 13272 (“Proper Consideration of Small Entities in Agency Rulemaking”) and DOT's procedures and policies to promote compliance with the Regulatory Flexibility Act to ensure that potential impacts of draft rules on small entities are properly considered. The changes proposed in this Notice will enhance safety, and I certify that this proposal, if promulgated, would not have a significant economic impact on a substantial number of small entities.

E. Paperwork Reduction Act

This proposed rule may result in a minimal change in information collection and recordkeeping burden under OMB Control Number 2137-0559, due to editorial changes to §§ 173.314 and 173.319 regarding HMR requirements to notify BOE whenever a Start Printed Page 49851rail car containing a time-sensitive product is not received by the consignee within 20 days from shipment. Since BOE no longer exists, we are proposing to remove references to BOE in §§ 173.314 and 173.319, and replace them with references to FRA. This proposed rule may result in a minimal change in burden since FRA instead of BOE will now be notified if a rail car containing a time-sensitive product is not received within 20 days from shipment. RSPA currently has an approved information collection under OMB Control Number 2137-0559, “Requirements for Rail Tank Car Tanks—Transportation of Hazardous Materials by Rail” with 2,759 burden hours which expires on May 31, 2006.

Section 1320.8(d), Title 5, Code of Federal Regulations requires that RSPA provide interested members of the public and affected agencies an opportunity to comment on information collection and recordkeeping requests. This notice identifies a new information collection request that RSPA will submit to OMB for approval based on the requirements in this proposed rule.

RSPA has developed burden estimates to reflect changes in this proposed rule. RSPA estimates the total information and recordkeeping burden as proposed in this rule as: Requirements for Rail Tank Car Tanks—Transportation of Hazardous Materials by Rail” OMB Number 2137-0559:

Total Annual Number of Respondents: 266.

Total Annual Responses: 16,781.

Total Annual Burden Hours: 2,689.

Total Annual Burden Cost: $102,586.25.

Requests for a copy of this information collection should be directed to Deborah Boothe or T. Glenn Foster, Office of Hazardous Materials Standards (DHM-10), Research and Special Programs Administration, Room 8430, 400 Seventh Street, SW., Washington, DC 20590-0001, telephone (202) 366-8553.

All comments should be addressed to the Dockets Unit as identified in the ADDRESSES section of this rulemaking, and received prior to the close of the comment period identified in the DATES section of this rulemaking. In addition, you may submit comments specifically related to the information collection burden to the RSPA Desk Officer, OMB, at fax number 202-395-6974. Under the Paperwork Reduction Act of 1995, no person is required to respond to an information collection unless it displays a valid OMB control number.

F. Regulation Identifier Number (RIN)

A regulation identifier number (RIN) is assigned to each regulatory action listed in the Unified Agenda of Federal Regulations. The Regulatory Information Service Center publishes the Unified Agenda in April and October of each year. The RIN number contained in the heading of this document can be used to cross-reference this action with the Unified Agenda.

G. Unfunded Mandates Reform Act

This proposed rule does not impose unfunded mandates under the Unfunded Mandates Reform Act of 1995. It does not result in costs of $120.7 million or more to either state, local, or tribal governments, in the aggregate, or to the private sector, and is the least burdensome alternative that achieves the objective of the rule.

H. Environmental Assessment

The National Environmental Policy Act of 1969 (NEPA), as amended (42 U.S.C. 4321-4347) requires Federal agencies to consider the consequences of major Federal actions and prepare a detailed statement on actions significantly affecting the quality of the human environment. We developed an assessment to determine the effects of the proposed revisions on the environment and whether a more comprehensive environmental impact statement may be required. We have tentatively concluded that there are no significant environmental impacts associated with this proposed rule. Interested parties, however, are invited to review the Environmental Assessment available in the docket and to comment on what environmental impact, if any, the proposed regulatory changes would have.
