City Responses to TEA's Questions on Temporary Dump Sites

TEA Question 1: 

Is there any water or soil testing being done just outside the perimeter of the dumpsites to see if there is any contamination?  For example, at Etienne Brule Park which is meters away from the Humber River?

City Answer 1:

The City has a storm water management plan that takes reasonable measures to ensure that any contaminated storm water arising from runoff from the sites does not enter storm sewers or natural water courses. The plan includes placing covers over the storm drains to prevent water from entering the storm sewer system, placing socks at key locations within the site to absorb liquids and reduce contaminants from entering the catch basins, and placing booms around sections of the site perimeter to reduce the possibility of contaminated storm water from running off the site and into the storm sewer system or natural water course. The plan also includes the use of vacuum trucks to clean out catch basin sumps and areas of water ponding within the sites themselves.   We have reviewed this Plan with the Ministry of the Environment and we provide ongoing updates.  We are meeting the MOE on Monday to provide another update.

In the case of Etienne Brule Park, the City plans to place booms at key locations along the site perimeter to contain runoff and prevent it from entering the Humber River.


TEA Question 2: 

Can the City provide details of how they will clean up the temporary dump sites once they are no longer in use to ensure that any long term contamination from the garbage and pesticides is elminated before the public can access the area?

City Answer 2:

Staff intend to use front-end loaders and trucks to clear the majority of the waste. It may be necessary to remove some waste by hand in areas that are not accessible by heavy equipment. The hard surfaces will be power-washed to remove debris and excess water will be contained by the use of booms. Similar to the storm water management plan, vacuum trucks will be used to clean out catch basin sumps and areas of water ponding.


Regarding Soil Testing:

The following was taken from the City of Toronto's website (see: http://www.toronto.ca/labour-relations/pesticide-odour-control.htm)

"After permethrin has been applied outdoors, it may be present in the soil and on the surface of plants, but is broken down in sunlight. Permethrin on soil and plant surfaces may be washed into surface waters by rain.

To ensure safety, the temporary garbage sites located on paved surfaces will be swept and flushed after all garbage has been removed.

The soil or grassy areas used as temporary waste sites (only Moss Park) will be lined with tarpaulins thus limiting soil contamination concerns.

In the sites adjacent to parks facilities such as playgrounds and sports fields, the soil will be tested and remediated on a priority basis with appropriate measures."
