PART 1105—PROCEDURES FOR IMPLEMENTATION OF ENVIRONMENTAL LAWS Authority: 16 U.S.C. 1456 and 1536; 42 U.S.C. 4332 and 6362(b); 49 U.S.C. 1301 note (1995) (Savings Provisions), 1321(a), 10502, and 10903-10905; 54 U.S.C. 306108. Source: 56 FR 36105, July 31, 1991, unless otherwise noted. § 1105.1 Purpose. These rules are designed to assure adequate consideration of environmental and energy factors in the Board's decisionmaking process pursuant to the National Environmental Policy Act, 42 U.S.C. 4332; the Energy Policy and Conservation Act, 42 U.S.C. 6362(b); and related laws, including the National Historic Preservation Act, 16 U.S.C. 470f, the Coastal Zone Management Act, 16 U.S.C. 1451, and the Endangered Species Act, 16 U.S.C. 1531. § 1105.2 Responsibility for administration of these rules. The Director of the Office of Environmental Analysis is delegated the authority to sign, on behalf of the Board, memoranda of agreement entered into pursuant to 36 CFR 800.5(e)(4) regarding historic preservation matters. The Director of the Office of Environmental Analysis is responsible for the preparation of documents under these rules and is delegated the authority to provide interpretations of the Board's National Environmental Policy Act (NEPA) process, to render initial decisions on requests for waiver or modification of any of these rules for individual proceedings, and to recommend rejection of environmental reports not in compliance with these rules. This delegated authority shall be used only in a manner consistent with Board policy. Appeals to the Board will be available as a matter of right. [81 FR 8853, Feb. 23, 2016] § 1105.3 Information and assistance. Information and assistance regarding the rules and the Board's environmental and historic review process is available by writing or calling the Office of Environmental Analysis. [81 FR 8853, Feb. 23, 2016] § 1105.4 Definitions. In addition to the definitions contained in the regulations of the Council on Environmental Quality (40 CFR part 1508), the following definitions apply to these regulations: (a) Act (b) Applicant (c) Board (d) Environmental Assessment (e) Environmental documentation (f) Environmental Impact Statement (g) Environmental Report (1) Provides notice of the proposed action; and (2) Evaluates its environmental impacts and any reasonable alternatives to the action. An environmental report may be in the form of a proposed draft Environmental Assessment or proposed draft Environmental Impact Statement. (h) Filing (i) Office of Environmental Analysis (j) Third-Party Consultant i.e., [56 FR 36105, July 31, 1991, as amended at 64 FR 53268, Oct. 1, 1999; 81 FR 8853, Feb. 23, 2016] § 1105.5 Determinative criteria. (a) In determining whether a “major Federal action” (as that term is defined by the Council on Environmental Quality in 40 CFR 1508.18) has the potential to affect significantly the quality of the human environment, the Board is guided by the definition of “significantly” at 40 CFR 1508.27. (b) A finding that a service or transaction is not within the STB's jurisdiction does not require an environmental analysis under the National Environmental Policy Act or historic review under the National Historic Preservation Act. (c) The environmental laws are not triggered where the STB's action is nothing more than a ministerial act, as in: (1) The processing of abandonments proposed under the Northeast Rail Services Act (45 U.S.C. 744(b)(3)); (2) Statutorily-authorized interim trail use arrangements under 16 U.S.C. 1247(d) [ see, (3) Financial assistance arrangements under 49 U.S.C. 10904 ( see Finally, no environmental analysis is necessary for abandonments that are authorized by a bankruptcy court, or transfers of rail lines under plans of reorganization, where our function is merely advisory under 11 U.S.C. 1166, 1170, and 1172. [56 FR 36105, July 31, 1991; 56 FR 49821, Oct. 1, 1991; 81 FR 8853, Feb. 23, 2016] § 1105.6 Classification of actions. (a) Environmental Impact Statements will normally be prepared for rail construction proposals other than those described in paragraph (b)(1) of this section. (b) Environmental Assessments will normally be prepared for the following proposed actions: (1) Construction of connecting track within existing rail rights-of-way, or on land owned by the connecting railroads; (2) Abandonment of a rail line (unless proposed under the Northeast Rail Services Act or the Bankruptcy Act); (3) Discontinuance of passenger train service or freight service (except for discontinuances of freight service under modified certificates issued under 49 CFR 1150.21 and discontinuances of trackage rights where the affected line will continue to be operated); (4) An acquisition, lease or operation under 49 U.S.C. 10901, 10902, or 10907, or consolidation, merger or acquisition of control under 49 U.S.C. 11323 and 14303, if it will result in either (i) Operational changes that would exceed any of the thresholds established in § 1105.7(e) (4) or (5); or (ii) An action that would normally require environmental documentation (such as a construction or abandonment); (5) A rulemaking, policy statement, or legislative proposal that has the potential for significant environmental impacts; and (6) Any other proceeding not listed in paragraphs (a) or (c) of this section. (c) No environmental documentation will normally be prepared (although a Historic Report may be required under section 1105.8) for the following actions: (1) Any action that does not result in significant changes in carrier operations ( i.e., (i) An acquisition, lease, or operation under 49 U.S.C. 10901, 10902, or 10907, or consolidation, merger, or acquisition of control under 49 U.S.C. 11323 and 14303 that does not come within subsection (b)(4) of this section. (ii) Transactions involving corporate changes (such as a change in the ownership or the operator, or the issuance of securities or reorganization) including grants of authority to hold position as an officer or director; (iii) Declaratory orders, interpretation or clarification of operating authority, substitution of an applicant, name changes, and waiver of lease and interchange regulations; (iv) Pooling authorizations, approval of rate bureau agreements, and approval of shipper antitrust immunity; (v) Determinations of the fact of competition; (2) Rate, fare, and tariff actions; (3) Common use of rail terminals and trackage rights; (4) Discontinuance of rail freight service under a modified certificate issued pursuant to 49 CFR 1150.21; (5) Discontinuance of trackage rights where the affected line will continue to be operated; and (6) A rulemaking, policy statement, or legislative proposal that has no potential for significant environmental impacts. (d) The Board may reclassify or modify these requirements for individual proceedings. For actions that generally require no environmental documentation, the Board may decide that a particular action has the potential for significant environmental impacts and that, therefore, the applicant should provide an environmental report and either an EA or an EIS will be prepared. For actions generally requiring an EA, the Board may prepare a full EIS where the probability of significant impacts from the particular proposal is high enough to warrant an EIS. Alternatively, in a rail construction, an applicant can seek to demonstrate (with supporting information addressing the pertinent aspects of § 1105.7(e)) that an EA, rather than an EIS, will be sufficient because the particular proposal is not likely to have a significant environmental impact. Any request for reclassification must be in writing and, in a rail construction, should be presented with the prefiling notice required by § 1105.10(a)(1) (or a request to waive that prefiling notice period). (e) The classifications in this section apply without regard to whether the action is proposed by application, petition, notice of exemption, or any other means that initiates a formal Board proceeding. [56 FR 36105, July 31, 1991, as amended at 81 FR 8853, Feb. 23, 2016] § 1105.7 Environmental reports. (a) Filing. (b) At least 20 days prior to the filing with the Board of a notice of exemption, petition for exemption, or an application for abandonment or discontinuance, the applicant must serve copies of the Environmental Report on: (1) The State Clearinghouse of each State involved (or other State equivalent agency if the State has no clearinghouse); (2) The State Environmental Protection Agency of each State involved; (3) The State Coastal Zone Management Agency for any state where the proposed activity would affect land or water uses within that State's coastal zone; (4) The head of each county (or comparable political entity including any Indian reservation) through which the line goes; (5) The appropriate regional offices of the Environmental Protection Agency; (6) The U.S. Fish and Wildlife Service; (7) The U.S. Army Corps of Engineers; (8) The National Park Service; (9) The Natural Resources Conservation Service; (10) The National Geodetic Survey (formerly known as the Coast and Geodetic Survey) as designated agent for the National Geodetic Survey and the U.S. Geological Survey; and (11) Any other agencies that have been consulted in preparing the report. (c) Certification. (d) Documentation. (e) Content. (1) Proposed action and alternatives. (2) Transportation system. (3) Land use. (ii) Based on consultation with the U.S. Soil Conservation Service, state the effect of the proposed action on any prime agricultural land. (iii) If the action affects land or water uses within a designated coastal zone, include the coastal zone information required by § 1105.9. (iv) If the proposed action is an abandonment, state whether or not the right-of-way is suitable for alternative public use under 49 U.S.C. 10905 and explain why. (4) Energy. (ii) Describe the effect of the proposed action on recyclable commodities. (iii) State whether the proposed action will result in an increase or decrease in overall energy efficiency and explain why. (iv) If the proposed action will cause diversions from rail to motor carriage of more than: (A) 1,000 rail carloads a year; or (B) An average of 50 rail carloads per mile per year for any part of the affected line, quantify the resulting net change in energy consumption and show the data and methodology used to arrive at the figure given. To minimize the production of repetitive data, the information on overall energy efficiency in § 1105.7(e)(4)(iii) need not be supplied if the more detailed information in § 1105.7(e)(4)(iv) is required. (5) Air. (A) An increase in rail traffic of at least 100 percent (measured in gross ton miles annually) or an increase of at least eight trains a day on any segment of rail line affected by the proposal, or (B) An increase in rail yard activity of at least 100 percent (measured by carload activity), or (C) An average increase in truck traffic of more than 10 percent of the average daily traffic or 50 vehicles a day on any affected road segment, quantify the anticipated effect on air emissions. For a proposal under 49 U.S.C. 10901 (or 10502) to construct a new line or reinstitute service over a previously abandoned line, only the eight train a day provision in subsection (5)(i)(A) will apply. (ii) If the proposed action affects a class I or nonattainment area under the Clean Air Act, and will result in either: (A) An increase in rail traffic of at least 50 percent (measured in gross ton miles annually) or an increase of at least three trains a day on any segment of rail line, (B) An increase in rail yard activity of at least 20 percent (measured by carload activity), or (C) An average increase in truck traffic of more than 10 percent of the average daily traffic or 50 vehicles a day on a given road segment, then state whether any expected increased emissions are within the parameters established by the State Implementation Plan. However, for a rail construction under 49 U.S.C. 10901 (or 49 U.S.C. 10502), or a case involving the reinstitution of service over a previously abandoned line, only the three train a day threshold in this item shall apply. (iii) If transportation of ozone depleting materials (such as nitrogen oxide and freon) is contemplated, identify: the materials and quantity; the frequency of service; safety practices (including any speed restrictions); the applicant's safety record (to the extent available) on derailments, accidents and spills; contingency plans to deal with accidental spills; and the likelihood of an accidental release of ozone depleting materials in the event of a collision or derailment. (6) Noise. (i) An incremental increase in noise levels of three decibels Ldn or more; or (ii) An increase to a noise level of 65 decibels Ldn or greater. If so, identify sensitive receptors ( e.g., (7) Safety.
