[GreenYes] Re: Wisconsin requires plans to shorten time for organic stability at landfills

["Eric Lombardi" <eric@no.address>]

Score a big win for Waste Management and the technology called
"bioreactors".   In my opinion, this development will result in a
nearly-official endorsement of bioreactors for all the material that isn't
"diverted".   The other option, "pretreatment", which I support using the
anaerobic digestion technology, won't stand a financial chance as long as
bioreactors-on-the-cheap are allowed to be built.  John, how could you let
this happen?   :-)

Subject: [GreenYes] Wisconsin requires plans to shorten time for organic
stability at landfills

 

For your information 

As of January 1st, Wisconsin now requires that landfill owners/operators
develop plans and implement systems to shorten the time for the degradation
of organics in landfills as a method to reduce long term environmental and
financial impacts. "Organics"  goes beyond food, and includes items such as
wood, yard materials, paper, textiles, and other materials. 

Under the new requirement, "The plan of operation for all new and expanded
municipal solid waste landfills submitted to the department after January 1,
2007 shall include a plan for significantly reducing the amount of
degradable organic material remaining after site closing in order to
materially reduce the amount of time the landfill will take to achieve
landfill organic stability."

While the state does not specify how organic stability is to be achieved,
three broad categories are: 

        1. Diversion 
        2. Pretreatment 
        3. Treatment within the landfill 

and a table of some alternatives and their status, pros and cons is
provided.  The following is the issue statement of the basis for this action
and a web page is provided at
http://dnr.wi.gov/org/aw/wm/solid/landfill/stability/index.htm. 

Issue Statement 

Current landfill designs and practices do not provide for degradation of
landfilled organic wastes within a defined and reasonable timeframe.
Undegraded organic wastes can potentially cause future environmental or
economic impacts if the landfill gas and leachate collection and containment
systems (cap and/or liner) fail at some time in the future. Potential
economic burdens and environmental risks associated with these undegraded
wastes will be largely borne by future generations. Better landfill designs
and organic management practices should be identified and implemented to
provide for organic waste degradation within a reasonable timeframe.

"Reasonable timeframe" means within the lifetime of the people who generate
the waste. 

"Economic burdens" means costs to manage gas and leachate, to maintain the
slopes and cover, to perform environmental monitoring, and to control
access.

"Environmental risks" includes potential contamination of groundwater and
surface water, air quality degradation, greenhouse gas impacts, explosive
gas generation, and/or land instability.

 

The rule and the guidance package was developed with the input of a
workgroup consisting of representatives of the Wisconsin DNR, the solid
waste industry, local government, the University of Wisconsin, and
consultants. The minutes and other materials are included on the above web
page. To the best of my knowledge, Wisconsin is the only state to have
developed this requirement.
