Question Received Before Prebid Conference

Q1: Since dewatering will be necessary for construction, is the water contaminated to a point that can’t be dumped to the PSB line or river?

A1: USIBWC has provided information on groundwater testing as Solicitation Attachment J.11

(GW Data MW-1 data 2012-2014.xlsx) and Appendix D of Solicitation Attachment J.10 (Design

Report Am Canal Lining 20160712.pdf). Additionally, Contractors were directed to www.recastingthesmelter.com for information about remediation of ASARCO in Section

00.31.26. On this website are groundwater testing results performed as part of their remediation.

Their last tests of groundwater from American Dam Island are dated March 2015. USIBWC cannot say whether the water pumped during construction will be contaminated or not.

El Paso Water Utilities can be contacted about using their sewer line. Water that meets the Clean

Water Act may be discharged to the Rio Grande.

1. Clean Water Act requires NPDES which requires a stormwater permit.

2. TCEQ TPDES General Permit TXR150000 allows discharge of "uncontaminated ground water or spring water, including foundation or footing drains where flows are not contaminated with industrial materials such as solvents" (Part II Section A 3.(g)).

3. 30 TAC §307.6(c)(1) includes Table 1 which lists Criteria in Water for Specific Toxic

Materials. Water meeting Table 1's Freshwater Acute Criteria is an uncontaminated discharge per TCEQ.
