Whittier Bridge/I-95 Improvement Project FEIR Chapter 1.0: Changes Since the Draft Environmental Impact Report and Resolution of Additional Issues The inclusion of the Shared-Use Path will increase access to public parks and recreation resources in the project area, including Maudsley State Park and Moseley Woods in Newburyport. A DEP-approved sampling program was conducted on October 20 and 21, 2011. Based on the results of the chemical testing, and the fact that the dredged material is from a riverine environment, MassDOT does not believe that the dredged material will be suitable for beach nourishment. 310 CMR 9.35: Standards to Preserve Water-Related Public Rights - Complies with applicable standards governing the preservation of water-related public rights, according to the provisions of 310 CMR 9.35; 310 CMR 9.35 (1) General: preservation of rights held by the Commonwealth in trust for public use of tidelands for lawful purposes; preservation of public rights of access. The project will not interfere with the rights held by the Commonwealth in trust for benefit of the public. 310 CMR 9.35(2) - Public Rights Applicable to all Waterways 310 CMR 9.35(2)(a) Navigation. The project will not interfere with public rights of navigation. The new Merrimack River crossing includes three sets of piers for each bridge structure, totaling six piers in the waterway for the northbound and southbound structures. There will be four spans or openings beneath both bridges, with the existing navigable federal and steamboat channels maintained for marine traffic. The bridge piers for both structures will be constructed in the same east-west alignment. The permanent bridge structures will increase vertical and horizontal clearance and there will be no adverse impacts to navigation. Appropriate channel markers and navigational lighting will provide permanent navigation safety features. 310 CMR 9.35(2)(b) - Free Passage Over and Through Water The rights to float on, swim in or move freely within the water column of the Merrimack River will be maintained and the project will not impede free passage over and through the water. 310 CMR 9.35(2)(c) - Access to Town Landings - There are no town landings within the vicinity of the project. 310 CMR 9.35(3) Public Rights Applicable to Tidelands and Great Ponds 310 CMR 9.35(3)(a) - Fishing and Fowling - The project will not pose a substantial obstacle to the public‘s ability to fish or fowl in the project vicinity or interfere with traditional fishing or fowling locations used by the public. 310 CMR 9.35(3)(b) - On-Foot Passage – The project will not interfere with public passage and useage of tidelands. 310 CMR 9.35(4) Compensation for Interference with Public Rights in Commonwealth Tidelands and Great Ponds. Not applicable. The project does not include the private use of Commonwealth Tidelands. All structures built in conjunction with the project will be public. 310 CMR 9.35(5) Management of Areas Accessible to the Public. There will be no change in the management of areas accessible to the public. 1-52

Whittier Bridge/I-95 Improvement Project FEIR Chapter 1.0: Changes Since the Draft Environmental Impact Report and Resolution of Additional Issues 310 CMR 9.35(6) Limitation on Liability. Not applicable. 310 CMR 9.36 Standards to Protect Water-Dependent Uses 310 CMR 9.36 (1) - General - preserve the availability and suitability of tidelands in use for water dependent purposes. The project will not interfere with the use of tidelands for water dependent purposes. 310 CMR 9.36 (2) - Private Access to Littoral or Riparian Property. Not applicable 310 CMR 9.36(3) - No disruption to water-dependent use in operation. The project will not result in the displacement of any water dependent uses on the Merrimack River 310 CMR 9.36(4) No displacement of water-dependent use that has occurred within five years. Phased construction of the northbound and southbound bridge structures would minimize adverse effects to river navigation. In-water work will occupy only part of the river at one time, maintaining the channels for navigation. Channel closures or restrictions on river traffic would be communicated in advance, enabling river users to accommodate their schedules without undue interruption. Additional tugs may be needed to assist vessels through areas of reduced clearances, especially during times of high volume of marine traffic (e.g., summer months). The Merrimack River navigation channels will remain open to marine traffic for most of the construction period, except for temporary closures of short duration for the bridge construction. Such times are expected to include floating the proposed bridge spans over the channels into place and dismantling the existing bridge superstructure over the navigation channels. Directives of the U.S. Coast Guard (USCG) regarding navigational traffic will be followed, including local notice to mariners. The USCG and local harbormasters will be kept informed of all construction activity potentially affecting marine traffic. 310 CMR 9.36 (5) No fill or structures which pre-empt water-dependent industrial uses within a DPA. Not applicable. 310 CMR 9.37 Engineering and Construction Standards 310 CMR 9.37(1) Complies with applicable standards governing engineering and construction of structures, according to the provisions of 310 CMR 9.37: 310 CMR 9.37(1) (a) Designed and constructed as certified by a Professional Engineer - The project was designed in accordance with standard engineering practices and project plans are stamped by various professional engineering disciplines (structural, civil) as applicable to the design type. 310 CMR 9.37(1)(b) Compliance with applicable state requirements for construction in flood plains (per state building code) and will not impose an unreasonable threat to public safety - Although the bridge replacement project is located within the 100-year flood zone and floodway of the Merrimack River, the new bridge, similar to the existing bridge, will not impose a threat to public safety in terms of flooding. 310 CMR 9.37(1)(c ) Does not unreasonably restrict the ability to dredge any channels - The U.S. Army Corps of Engineers maintains the federal navigation channel.
