叶子已经改变，雪开始落在全国各地的几个地方。到这个时候，建设项目疯狂地试图涂上分级，景观和其他户外任务。但是你的项目在本赛季期间俯瞰着大型雨水任务？

As we know, northern winters in the U.S. can be brutally cold, snowy, or mild with little to no snow. Preparing your site to handle the winter will greatly reduce your stormwater best management practice (BMP) maintenance and allow a quicker return to work come spring. Here are a few tips and tricks project owners and supervisors should be considering:

最好的冬季BMP是建立植被。考虑在冬季准备您的网站时萌发时间。

2.种子和卷曲稻草是recommended temporary stabilization technique for nearly all scenarios. Ensure the straw is properly crimped into thawed ground before freezing up conditions. October 15^this a key date to finish stabilizing soils in preparation for winter.

一种。If winter has snuck up on you, stabilization is still required, but techniques change. Crimping is difficult or impossible after the ground freezes. The明尼苏达州Stormwater Manualhas some great resources on snow mulching where they detail how to stabilize after winter has set in.

3.对于城市环境中的项目，评估您将路边周边控制（如淤泥栅栏和过滤器原木）移动到路边的能力，以最大限度地减少扫雪机损坏。

4. Consider plow routes and locations where snow will be stored throughout your project site (if needed). Ensure perimeter controls will not be damaged as snow piles grow and melt run-off may concentrate and overwhelm BMPs.

5. If sanding and/or salting operations will occur on your site, consider the downstream cumulative effects to vegetation, soils, and permanent stormwater management features that are not fully constructed or established. Potential upgradient BMPs to divert flows from these areas may need to be installed before freeze up.

6.在任何机会冻结或雪之前清洁街道。扫地者和幻影游戏在冬季无法工作。斯普利特可用于清洁冬季道路的沉积物。

7.如果您的项目在明尼苏达州，则入口保护必须保持整个冬季。几个城市，县和流域都有自己的法规，要求通过某些日期删除入口保护，大部分是11月15日^th.

一种。明尼苏达污染管制局确实允许临时删除入口保护，如果冻结，可以创造公共安全问题。
b. If any inlet protections are removed, or BMPs in general are moved or removed, documentation in the SWPPP is required.

8.检查可以暂停 - 如果没有发生地面干扰，您的网站已经冻结了地面条件。但是，如果发生热身，每周检查确实需要再次启动。

一种。Additionally, if ground conditions remain frozen, but a day or two of warm weather occurs — after runoff, or post-storm event inspections, are required within 24 hours of the event. Runoff is defined as precipitation or melt water moving on site far enough to discharge from the site either via a perimeter control, or a permanent stormwater system.
