Limited Reuse Soils (LRS)

Limited Reuse Soils (or Mildly Contaminated Soils) is an evolving topic.  Please consult the NHDOT and NHDES for the most up to date regulations and information.

Municipality FAQs

What can be done with your excavated materials to their residents? - Unless the LRS soils / street waste soils (sweepings, ditch digging, etc.) have been tested and are determined to not be contaminated (above naturally occurring background) by an environmental consultant (preferably a licensed Professional) there should not be an avenue where these soils are provided to residents. A waiver for the residents of the municipality would not relieve a municipality of their responsibility under state regulations. 

Do any towns have a waiver? - Municipalities can apply for a NHDES waiver to the solid waste rules to manage their street waste soils.

What to do with your growing stockpiles? – If a municipality wants to use the soils without restriction, it is advised that they have their stockpiles tested and the results reviewed by an environmental consultant (preferably a licensed Professional). If they don’t want to go that route, soils generated from street work should be considered a solid waste and should be managed consistent with Env-SW-903. A waiver from those rules, similar to that which the NHDOT has, is an available avenue to allow use of this material in a prescribed fashion.

Managing a diverse road network requires lots of tools in your toolbox!  Effective winter road maintenance might include the use of products such as sand, crushed stone, salt, or brine - individually or in combination with other treatments (such as the use of a mixed 3/8” stone and winter sand on gravel roads).  Factors that determine which method is recommended include road condition, road surface (paved, gravel, or dirt), weather conditions and forecast (precipitation rate, type, temperature), posted speed, and sensitivity to environmental ecology and residential areas.  Federal Highway Administration (FHWA), Department of Transportation (DOT) and other highway and public works organizations offer a variety of publications to educate road practitioners on best practices and decision making in regards to which materials to use -sand, abrasives, salt, or other chemical deicers; when; and in what quantities.  A material such as crushed stone may be effective on gravel roads but is generally not recommended on paved roads.  Using sand may be necessary during extreme cold and icing events, but could impact streams during rain or runoff events.  Awareness of MS4 and silica dust impact, including in and around our critical water streams, is of importance. 

While we cannot escape winter in New Hampshire, and although there isn’t a one size fits all approach, understanding the unique strengths of each method of winter maintenance and knowing the roadways in their communities can allow public works professionals to effectively use road treatments to maintain passable roads while minimizing environmental impact and maximizing winter maintenance budgets.
