Air Emissions Management Plan for the Westridge Marine Terminal

Trans Mountain must file with the NEB for approval,

at least 4 months prior to

commencing construction at the Westridge Marine Terminal

, an Air Emissions

Management Plan for the Westridge Marine Terminal that includes:

a) locations of air monitoring sites (on a map or diagram), including the rationale

for the locations selected;

b) confirmation that the new fixed air monitoring stations will be installed and

operating at least one year prior to commencing operations at the Westridge

Marine Terminal to establish robust local baseline data;

c) the methods and schedule for ambient monitoring of contaminants of potential

concern in air (e.g., particulate matter [including diesel particulate matter and

speciation of PM

2.5

], nitrogen oxides (including NO

2

), sulphur dioxide, hydrogen

sulphide, ozone, mercaptans, reduced visibility and volatile organic compounds)

following a recognized protocol (e.g. National Air Pollution Surveillance program

or U.S. Environmental Protection Agency), and emissions source tracking;

d) representative meteorological data (e.g. wind speed, wind direction, air

temperature and relative humidity) for the monitoring period;

e) description of monitoring equipment and procedures for monitoring station

data recording, assessment, quality assurance and reporting details, including a

description of how the real time and non-continuous air quality monitoring data

will be made available to the public;

f) a particulate matter management plan;

g) a description of the public and Aboriginal communication and complaint

response processes;

h) the criteria or thresholds that, if triggered or exceeded, would require

implementing additional mitigation measures;

i) a description of additional mitigation measures that would be implemented as a

result of the monitoring data or ongoing concerns; and

j) a summary of its consultations with Appropriate Government Authorities,

potentially affected Aboriginal groups and affected landowners/tenants. In its

summary, Trans Mountain must provide a description and justification for how

Trans Mountain has incorporated the results of its consultation, including any

recommendations from those consulted, into the plan.
