c) maintain at each of its construction oﬃces:

the relevant environmental portion of the commitments tracking table listing all

of Trans Mountain’s regulatory commitments, including those from the Project

application and subsequent ﬁlings, and environmental conditions or site-speciﬁc

mitigation or monitoring measures from permits, authorizations, and approvals

for the Project issued by federal, provincial, or other permitting authorities;

ii) copies of any permits, authorizations, and approvals referenced in i); and

iii) copies of any subsequent variances to permits, authorizations, and approvals

referenced in i).

Environmental and socio-economic assessment - route re-alignments

As applicable, Trans Mountain must ﬁle with the NEB for approval,

concurrent with

its ﬁling of the Plan, Proﬁle and Book of Reference pursuant to section 33 of the

National Energy Board Act

, an environmental and socio-economic assessment for

each proposed detailed route re-alignment that extends beyond the applied-for

corridor width of Trans Mountain’s preferred route in proximity to:

• Ohamil Indian Reserve 1;

• Tzeachten Indian Reserve 13; and

• Surrey Bend Regional Park.

Any assessment must include:

a) environmental alignment sheets at an appropriate scale, clearly depicting the

proposed route re-alignments;

b) results of any pre-construction surveys within the areas that were not previously

subject to such surveys, and an indication of potential residual eﬀects;

c) all associated mitigation measures that are beyond those identiﬁed during the

OH-001-2014 proceeding;

d) analysis supporting the use of the measures in c), including any supplementary

reports;

e) conﬁrmation that Trans Mountain will update the relevant Environmental

Protection Plan(s) to include any relevant information based on any

supplemental surveys completed; and

f) a summary of consultations with Appropriate Government Authorities,

potentially aﬀected Aboriginal groups and aﬀected landowners/tenants, as well

as copies of all written comments that may be provided to Trans Mountain by

those consulted. 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

assessment.

Design temperatures – terminals and pump stations

Trans Mountain must ﬁle with the NEB,

at least 3 months prior to ordering pipe for

terminals and pump stations

, conﬁrmation, with rationale, that:

a) the selected maximum and minimum design temperatures are in accordance

with CSA Z662-15, Clause 5.2.1;

b) the selected design temperatures are based on historical, location-speciﬁc

extreme daily maximum and minimum temperatures, as opposed to average

temperatures; and

c) the extent of the historical weather data used is commensurate with the

expected operational life of the Project.
