SS Prerequisite 1: Construction Activity Pollution Prevention
Required

Intent
To reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation.

Requirements
Create and implement an erosion and sedimentation control plan for all construction activities associated with the project. The plan must conform to the erosion and sedimentation requirements of the 2003 EPA Construction General Permit OR local standards and codes, whichever is more stringent. The plan must describe the measures implemented to accomplish the following objectives:

- To prevent loss of soil during construction by stormwater runoff and/or wind erosion, including protecting topsoil by stockpiling for reuse.
- To prevent sedimentation of storm sewers or receiving streams.
- To prevent pollution of the air with dust and particulate matter.
The EPA’s construction general permit outlines the provisions necessary to comply with Phase I and Phase II of the National Pollutant Discharge Elimination System (NPDES) program. While the permit only applies to construction sites greater than 1 acre, the requirements are applied to all projects for the purposes of this prerequisite. Information on the EPA construction general permit is available at http://cfpub.epa.gov/npdes/stormwater/cgp.cfm.

Potential Technologies & Strategies
Create an erosion and sedimentation control plan during the design phase of the project. Consider employing strategies such as temporary and permanent seeding, mulching, earthen dikes, silt fencing, sediment traps andsediment basins.

SSP 1: 建设活动污染防治
必要

目的
通过控制土壤流失、水道沉积、扬尘产生等措施，减少建筑活动产生的污染。

要求
制定并实施一个对于所有施工活动的水土流失和沉积控制方案，该方案必须遵守环保署的“施
工通用要求”2003，或地方标准、规范，取其中要求较严。方案必须有关以下方面的实施措施：
-- 防止由于雨水冲刷和大风可能造成的土壤流失，以及覆盖表土再利用。
-- 防止因雨水冲刷、汇集产生沉积。
-- 防止扬尘和颗粒物产生。
环保署的通用要求给出了符合“应对污染物释放国家计划(NPDES)”阶段一和阶段二预案要求，
虽然这个通用要求只适用于大于一英亩的场址工程，但所有LEED 工程必须遵守。环保属的施
工通用要求可在此查阅，http://cfpub.epa.gov/npdes/stormwater/cgp.cfm.

技术措施和策略
工程设计阶段时就考虑制定一个水土流和沉积控制方案，可采取一些措施，例如种植、覆盖、
土坝、过滤格栅、围栏沉积控制池等。
