protected from construction-related sediment loadings. Construction BMPs must
be maintained while construction or land disturbance activities continue.
Measures shall meet as a minimum the Best Management Practices set forth in the
4+992—as-amended, “New Hampshire Stormwater Manual, Volumes I. 3” and 2 any
published DES regulations.
Off-site surface water and runoff from undisturbed areas shall be diverted away
from disturbed areas where feasible or carried nonerosively through the project
area. Integrity of downstream drainage systems shall be maintained.
All temporary erosion and sediment control measures shall be removed after final
site stabilization. Trapped sediment and other disturbed soil areas resulting from
the removal of temporary measures shall be permanently stabilized within 30
days.
1. Stormwater management measures.

Structural stormwater management measures to achieve recharge, water quality,
and peak discharge control shall be structural BMP’s designed in accordance with
the requirements of the following:
(a)
Hampshire Stormwater Manual, Volumes 1-3.
(b) Best Management Practices for Urban Stormwater Runoff, published by
NH DES, 1996, as amended.
(c) Innovative Stormwater Treatment Technologies Best Management
Practices Manual, published by NH DES, May 2002, as amended
[Reference: http://www.des.state.nh.us/wmb/was/manual/]
The performance criteria specified in the Design Manual with regard to general
feasibility, conveyance, pretreatment, environment and landscaping, and
maintenance shall be considered in the selection of a structural BMP.
