Tire Bath

Filed under: Video — Tags: , , , , , , , , — Sheetflow @ 2:50 am

One of the most difficult things to manage on a construction project, especially a road project, is preventing mud from being tracked off the job. This video illustrates the use of a water-filled tire bath along with a rock entrance road and rock and asphalt exit onto existing road surface. Tire baths are useful when the there is a minimal amount of traffic leaving the project. Tire baths require a lot of maintenance including water changes and sediment removal.

Polymer Use and Testing for Erosion and Sediment Control on Construction Sites
By Scott Tobiason, David Jenkins, Ed Molash, Stacey Rush

Tested in the soggy La Niña weather conditions of the Pacific Northwest, chemical polymers promise a cost-effective, safe way to prevent soil erosion and remove suspended sediments from construction-site runoff.

Construction Stormwater General Permit

Construction Stormwater General Permit

Construction site operators are required to be covered by a Construction Stormwater General Permit if they are engaged in clearing, grading, and excavating activities that disturb one or more acres and discharge stormwater to surface waters of the state. Smaller sites may also require coverage if they are part of a larger common plan of development that will ultimately disturb one acre or more. Operators of regulated construction sites are required to:

  • Develop stormwater pollution prevention plans.
  • Implement sediment, erosion, and pollution prevention control measures.
  • Obtain coverage under this permit.

Construction General NPDES Permit Appealed

Filed under: Article — Tags: , , , , — Sheetflow @ 1:29 pm

On December 29th, 2010, the Puget Soundkeeper Alliance filed a Notice of Appeal with the Washington State Pollution Control Hearings Board. The appeal calls for a re-write and reissue as they consider the permit to be ” unlawful and unfair” because it does not meet the “requirements or intent” of the Clean Water Act, Environmental Protection Agency rules, Washington state water quality law ( RCW 98.40 and WAC 173-201A), or Department of Ecology rules.

Low Impact Development for Public Works Construction

Low Impact Development for Public Works Construction:
Erosion and Sediment Control Compliance

David S. Jenkins, Seattle, Washington

Introduction
Construction is a messy business; in the Puget Sound region of western Washington, with average annual rainfall of 40″ to 60″, it can also be challenging. Uncontrolled erosion from a construction site can generate 10-1000 times the quantity of sediment that occurs naturally from vegetated areas. Most construction in western Washington occurs near wetlands, streams, lakes, or the Puget Sound where sediment loss can reduce beneficial uses, or worse, destroy a salmon stream.

This paper will discuss proven methods that public works professionals can utilise to improve erosion control compliance and reduce project impacts.
