BMPs and stormwater treatment systems sized for the 20yr/1hr storm total runoff
volume). Alternative C is quantified under C20 (Alternative C built to comply with
TRPA codified regulations to treat the 20yr/1hr total runoff volume) and C100
(Alternative C built with BMPs, LID strategies and stormwater treatment systems
sized for the 100yr/1hr total runoff volume). Table 2 and 3 present the loads by
pound (lb) for a variety of water year conditions.
Comment 363-b: Comment Summary - Conceptual/preliminary water quality mitigation plan for the
preferred Alternative appears quite robust. Hope that the project proponents will
remain open to the possibility of conducting future monitoring studies at the site to
measure the effectiveness of these improvements from LID techniques.
The comment supporting the implementation of LID strategies and techniques is
noted. The Project commits to conducting post-project monitoring as a standard
practice of the Project. See SP-9 in Chapter 6. The monitoring program will be
developed based on the selected Alternative and submitting to NDEP and TRPA for
approval during project permitting. The monitoring program will be designed to
measure compliance with State and Regional discharge limits, qualify and quantify
performance of LID strategies and techniques and for further calibration of the LSCP
model assumptions.
Comment 363-c: Comment Summary - DEIS states that Project will participate in EIP project 732 but
does not describe how. Please clarify what the word participate means. Will Project
capture and treat offsite flows from EIP project 732 or do intend on contributing
funding to help design/construct EIP project? If the latter, how much has been or
will be contributed?
The Project EIP commitments are outlined in the CEP Resolution Letter (February 4,
2008) Environmental Improvements/ Environmental Improvement Program (EIP):
For allocations to be reserved and projects to be approved, CEP projects are required
to commit to substantial environmental improvements, which must include
specifically identified EIP projects. Your project proposes a number of environmental
benefits/improvements; however, TRPA requires a written commitment regarding the
funding, construction, and overall maintenance/monitoring for these EIP project
contributions in order to ensure the projects are implemented. The EIP concerns
listed in TRPA’s January 16, 2008 letter shall be addressed." The EIP Projects are
listed on page 2-18 of the DEIS, but are not detailed in this section.
Boulder Bay's portion of EIP Project No. 732 will be located on the California Parcel
and will construct underground infiltration gallery 9 of the stormwater treatment
system described for Alternatives C and D. EIP Project No. 714 will also be located
on the California Parcel to establish and manage the NSCP lake Vista Mini-Park on
the site above the infiltration gallery. The Project will capture and treat onsite and
offsite (from contributing watershed areas from Washoe County and SR 28 roadway
and ROW) runoff in the proposed stormwater treatment system within the project
area. Since the system is designed linearly, overflow from infiltration gallery 8 will
reach gallery 9 on the California Parcel. Runoff from the NDOT portion of this area
will continue to be treated by the existing treatment vault located at the corner of SR
28 and Stateline Road. Runoff from Washoe County portion of this area (Stateline
Road) will be treated with the use a new treatment vault with sand and oil separators
prior to infiltration in galley 9. The Project will fund the construction of this project
and has submitted draft agreement to TRPA concerning funding for long-term
