Subject: Air Quality Conformity/NEPA Support City of Nashua
Reference: HMMH Proposal Number P21-0240

Dear Christine:

Harris Miller Miller & Hanson Inc. (HMMH) is pleased to provide McFarland Johnson with this proposal to
conduct an air quality study for the Proposed Action to address National Environmental Policy Act (NEPA)
and Transportation Conformity. HMMH will provide the air quality analysis as described below.

SCOPE OF WORK

The assessment will be conducted consistent with the National Environmental Policy Act (NEPA) including
all Federal Highway Administration (FHWA), Environmental Protection Agency (EPA), and New Hampshire
Department of Transportation (NHDOT) regulations and guidance.

1. Task 1: Traffic Data Collection

HMMH will work with the traffic engineers during their analysis to ensure appropriate traffic data are
collected for use in the air quality study.

For the carbon monoxide (CO) analysis, which is detailed below, traffic will be needed for the East Hollis
Street, Bridge Street and Ferry Street including the intersections within the study area for the Existing,
Opening and Design Year conditions including the No-Build and Build Alternative. The traffic data needed
consists of peak AM and PM hourly volumes and level of service (LOS) for the signalized intersections.
Turning movement figures along with intersection signal timing and average daily traffic (ADT) volumes
should also be included.

2. Task 2: Applicable Level of Pollutants

A project level analysis is typically conducted for operational emissions of carbon monoxide (CO),
Particulate Matter, mobile source air toxics (MSATs), volatile organic compounds (VOCs) and nitrogen
oxides (NOx). The scope of work for each pollutant is project specific and based on expected traffic
volumes (which have not been completed) and the EPA attainment status of the study area. The Project
is located in Hillsborough County which is designated as attainment for all criteria pollutants except the
2010 sulfur dioxide standard and carbon monoxide(see below).

Sulfur Dioxide: All or parts of Hillsborough, Merrimack, and Rockingham counties are designated non-
attainment for the 2010 sulfur dioxide standard. However, this status only covers the towns of Candia,
Deerfield and Northwood, which are outside the project area; therefore, Conformity for SO2 does not

apply.

Christine Perron
September 27, 2021

Ozone: The 1-hour 1979 and 8-hour 1997 ozone standards have since been revoked and the area was
recently reclassified as unclassifiable/attainment for ozone.

Particulate Matter: The study area is located in an EPA designated attainment area for particulate matter
(PMio and PM25s); therefore, PMio and PM25s Transportation Conformity requirements do not apply for
projects located in Hillsborough County.

CO Hot-Spot Analysis: The cities of Manchester and Nashua are designated a maintenance area by EPA
for CO, therefore, projects in these areas may require a CO hot spot analysis (i.e. microscale analysis
Phase Il-Level Il study) to ensure compliance with the National Ambient Air Quality Standards (NAAQS).
The hot-spot analysis typically examines worst-case ground-level CO impacts due to traffic flow in the
immediate vicinity of a project intersection/interchange. Since the project is located in an attainment
area for CO and projected traffic at the intersection could result in a drop below an LOS of C and another
intersection with an expected LOS of F; a quantitative CO hot spot analysis is proposed to demonstrate
that project level air quality impacts would not exceed the CO NAAQS.

Greenhouse Gases: Based on the President’s recent Executive Order? , the project impacts should be
documented in the Environmental Assessment (EA) consistent with the 2016 CEQ Final GHG NEPA
guidance. In order to meet the 2016 CEQ guidance, a qualitative GHG analysis is proposed for this
project to document GHG impacts unless NHDOT determines that a GHG is not required for this project.

Microscale CO Hot-Spot Analysis

As discussed above, assuming a Phase Il analysis is required for the signalized intersections, a microscale
hot-spot analysis will be conducted at the East Hollis Street and Bridge Street intersection using the latest
versions of the EPA Mobile Vehicle Emissions Simulator (MOVES) and CAL3QHC models to estimate
worst-case CO concentrations at individual receptor (i.e. receiver) locations for the Existing, and future
Build and No Build conditions. The future Build Alternative traffic, roadway geometry, signal timing data
and nearby roadway receptor locations will be included. The modeling results will be added to
appropriate CO background concentrations and compared to the NAAQS.

Mesoscale Analysis

A mesoscale analysis is typically performed to assess the total VOCs and NO, (i.e. ozone precursors),
carbon dioxide (CO2) if applicable, methane and nitrous oxide associated with motor vehicle emissions
for each condition and Alternative compared to the No-build condition. The mesoscale analysis evaluates
the regional impact of VOC, NO, and greenhouse gas (if required) emissions affiliated with the project.
HMMH assumes a regional impact analysis (i.e. mesoscale) will not be required for this project.

HMMH assumes the Build Alternative will not significantly affect air quality and/or cause a violation of
the NAAQS, therefore a Phase III analysis will not be required to evaluate abatement alternatives. HMMH
assumes a quantitative (Phase II) will be required to address CO impacts (see above microscale CO hot-
spot).

3. Task 3: Mobile Source Air Toxics (MSATs)

On October 18, 2016, the FHWA issued updated interim guidance regarding Mobile Source Air Toxics
(MSATs) in a NEPA analysis to include the EPA’s recent MOVES2014a emission model along with updated
research on air toxic emissions from mobile sources. The guidance includes three categories and criteria

for analysing MSATs in a NEPA document; 1) No Meaningful MSAT effects; 2) Low Potential MSAT effects;
3) High Potential MSAT effects.

For projects with low potential MSAT effects, a qualitative assessment (Phase | analysis) of emissions
projections will be conducted in accordance with Appendix B and Appendix C of the FHWA guidance. For
projects with no meaningful MSAT effects, no formal analysis is required.

For Projects considered as high potential MSAT effects, (i.e. projects with traffic volumes greater than
140,000 to 150,000 AAWDT) a quantitative analysis (Phase II analysis) will be conducted to evaluate
MSAT emissions across roadway links within the “affected network”.

Based on expected ADT volumes for the Build Alternative (i.e. below 140,000 ADT), the Project is
assumed to be one of low potential MSAT effects and only a qualitative analysis will be required.

4. Task 4: Greenhouse Gases (GHGs)

Based on the President’s recent Executive Order? , the project impacts should be documented in the
Environmental Assessment (EA) consistent with the 2016 CEQ Final GHG NEPA guidance*. In order to
meet the 2016 CEQ guidance, a qualitative GHG analysis is proposed for this project to document GHG
impacts unless NHDOT decides a GHG analysis is not warranted.

5. Task 5: Reporting

HMMH will prepare a Draft Air Quality Study Report for NHDOT review, make the necessary revisions
resulting from the review, and then submit a final version of the report. The report will aim to provide
pertinent information in a manner understandable to the lay public. The report will include
documentation of the air quality analysis, including discussion of air quality standards, attainment status,
regulatory discussion, any modeling approach and assumptions, graphics, and tables of air quality impact
estimates for the Build Alternative and conditions. The technical report (including graphics) will be
provided in electronic format.
