Sludgewatch Admin:
Send in your comments to the MOE by January 5th, 2008 (yes, tomorrow)
The province of Ontario is floating the idea of doing away with waste
permits for sewage sludge and paper sludge spreading (along with some other
wastes).
This would have a dreadful effect on farm spreading of spreading...because
the gov't is also trying to sneak in all kinds of relaxed regulations,
reduced waiting periods, reduced separation distances from wells, and the
intend to remove most of the public transparency.
Write to Kevin Webster today. You may cut and past the letter below if you
wish or write comments all your own. Contact: Kevin.Webster at ontario.ca
For details of the proposal go to:

Dear Mr Webster,
Re: EBR Registry Number 010-1436
Issues with the proposed changes in the regulation of
Non Agricultural Source Materials
Overall Problem: Failure to require demonstration of agricultural benefit
NASM regulations are so opaque and unweildy only consultants can cut through
and understand them. The province of Ontario should maintain the use of
Certificate of Approval for the hauling and land application of sewage
sludge biosolids and paper mill sludges.
NASM that currently incorporates the Guidelines for the Use of Biosolids
and Other Wastes on Agricultural Lands in Certificates of Approval for
biosolids spreading. Under these permits the proponent must demonstrate
agricultural benefit and must demonstrate that the sludge or waste
ammendment does not pose a risk to the environment or public health before
it is land applied. The NASM regulations do not have this requirement.
This requirement should be written into the NASM requirements. Simply
limiting some metals and some nutrients and some large particles does not
ensure that the material has agricultural benefit and does not pose a risk
to the environment or health.
This requirement should be written into the regs and generators should have
to provide documentation of benefit and provide funds for a govt review of
the research to demonstrate benefit and environmental/public health safety.
(refers to sec 10 pg 13)
Haulers and Appliers to be exempted from need for Systems CofA
The Haulers and Appliers of NASM should continue to require a CofA
because of the opportunity to adulterate the NASM between the pick up and
delivery, and to provide a mechanism to address issues specific to different
NASM and NASM mixtures. The CofA allows the public to know who is
responsible for the material in trucks since the CofA is a public document.
There has been a history of poor behaviour in Ontario by some haulers. If
such haulers are allowed back into the NASM spreading business, the NASM
doesnt provide adequate enforcement mechanisms to address this type of
waste transportation problem. (sec 6.2 page 10)
The new Field Nutrient Management Plan
The proposed Field Nutrient Management Plan should be removed. The whole
idea of the legislation is for farms to be phased into the NMA regulation
requirements. To move to a situation where the farm isnt triggered but
just some discrete fields obviates the whole point the legislation. It
was already egregious that farms with high numbers of animal units were
triggered by the NMA but farms with annualized excrement of hundreds of
thousands of human beings were not triggered to prepare plans under the NMA.
Farmers who are taking NASM on their farms should have to prepare a whole
farm plan to harmonize the nutrient use and storage on the farm. In the
absence of this absentee landlords will be turning over their farms to
deregulated waste materials applied by deregulated waste haulers/appliers
and not have a full understanding of how their farm soil amendment practices
may impact their future farming or land use plans.
There should be no field plans. Just farm plans.
(sec 6.1 pag 9)
Section 9.3 Exception to registration
If the Director thinks the use of NASM may have an adverse effect then the
Director should have the authority to terminate or write conditions as they
see into the plans for that property no matter what category of NASM is
used.
Indeed why would the MOE/OMAF in this draft allow the Director discretion in
the least harmful and dangerous ammendments and not allow this discretion
with the most pathogenic and high metal contamination ammendments? This is
a dreadful proposal.
Foreign Objects:
Two percent of the NASM may include foreign objects. It is totally
unacceptable to allow foreign objects like glass, metal, plastic onto
Ontario farmland. These materials will stay in the soil permanently
and
can make the land forever unsuitable for some root crops like potatoes.
The presence of glass or metal in a potato or similar crop can break teeth
and cause high liability for the producer and processor of the crop.
Foreign objects should not be allowed in NASM certainly not 2%
Similarly the limit of 1% plastic has not been effective in stopping
terrible contamination of the countryside with blowing plastic bags
this
plastic poses a danger to wildlife like birds and fish and livestock, and
can cause lowered property values.
Illegal compost should not be allowed on farmland under NASM
The whole point of composting is to provide a material that is safe to use
without a waste CofA. To allow compost with large particle size on farmland
is to put that farmland at risk permanent impairment of the agricultural
soil. (sec 11.0 pg 13)
Restrictions on liquid application rate
The proposal is to weaken the provision limiting liquid NASM application
rates by allowing more liquid per hectare to be applied in the summer
period.
Already rural wells are being inundated by land applied liquid sludges.
Tile drains and bedrock, and other local features are not being adequately
managed to stop the flow of liquid sludges into groundwater and wells and
surface waters.
The use of liquid NASM should be reviewed against complaints of runoff and
well contamination and an expert panel should be developed to create best
management practices that are then written into the regulations.
Best management practices should include a requirement that muncipalities
were NASM is spread have NASM officers who attend when NASM is applied to
verify that there is no runoff and that all the requiements are met. NASM
generators should provide funds to receiving municipalities to finance these
positions. (sec 12.0 pg 14)
13.0 Organic Soils
Organic soils already have an exceedingly high content of organic matter
so there should be no application of NASM except lime materials if it is
needed to raise pH.
No other application of NASM should be permitted.
14.0 Soil Phosphorus
There should be no addition of NASM to soils that are at or exceed 60
milligrams of available phosphorus.
PHOSPHORUS ISSUE The formula for the addition of phosphorus under NMA is
loading up Ontario soils with phosphorus
which is the opposite of its intent
when first promulgated.
Needs an agronomic review by a speciality panel
I recommend Dr Les Evans
from U of Guelph
15.0 Soil pH
There should be no application of NASM where the soil pH is less than 6
since these soils can release toxic metals into the crop and into the
environment. Any liming agents that are also NASM should be free of
organic matter if they are applied to organic soils.
16.0 Minimum beneficial quality requirement
This wording is inadequate to demonstrate agricultural benefit. Just
because a material has some nutrient does not provide assurance that there
is no environment/health risk or detriment. NASM should meet the obligation
to demonstrate benefit and absence of health or environmental harm.
17.0
Criteria for metals
Ontario proposed originally to phase out the land application of
materials that that had the higher levels of metals. Instead of phasing out
the land application of those materials this proposal enshrines these high
heavy metals sludges and NASMs in the new regulatory framework with NO
provision for phase out.
There is no table to explain the sampling methods or test methodologies
required.
There should be no averaging of test results
all NASMs should be tested
directly before land application
so that the tests include the polymers and
thickeners used in the final stages of NASM preparation.
The WEAO report on biosolids conducted a few years ago pointed to some
metals of concern in Ontario that are not currently regulated in sludges
silver, thallium, tin etc.
There are also other contaminants of concern in Ontario NASMs like NP and
NPE, dioxins and furans, pharmaceuticals, hormones and standards should be
developed for the these substances in NASMs starting with immediate
inclusion of the problematic additional metals. Screening for a wide range
of toxins or problematic compounds should be part of the initial testing
work up for NASM demonstrated agricultural benefi and lack of harm.
18, Criteria for Pathogens
Recent research conducted for the Water Environment Research Foundation in
the USA has demonstrated that many sewage sludges that are anaerobically
digested and centrifuge dewatered are subject to an extraordinary rate of
pathogen regrowth and reactivation. There is a concern that anaerobic
digestion may not be killing pathogens and other bacteria but merely
putting them in a dormant state (viable non culturable).
Testing on NASM must include tests for this kind of regrowth. Also NASMs
may not have consistent levels of pathogens. Some may be seasonal or be
based on inputs from slaughterhouses or rendering plants etc. Provisions
need to include regular and routine testing to detect this kind of
variability.
Also, how do you know that a Category 1 material is really a Category 1
material if you dont require testing? All the materials need to be tested
and the tests reported to the MOE to demonstrate that they are the Category
they claim to be.
18.1
Category 3 and 4 NASM cannot rely on the sewage treatment plant to
guarantee acceptable pathogen reduction. The NASM needs to be tested to
determine the levels of pathogens.
Enteric viruses need to be included in the required testing protocols and
standards.

19.1 Setbacks from Surface water - public posting of farm plan at municipal
offices
Inadequate set backs 3 meters is inadequate as a set back to surface water
There should be a 20 meter set back
The mapping of the site should be posted in the community municipal council
office so that residents can review all the setbacks and features and
comment on the proposed application. Residents may know more about
intermittent streams, slope, bedrock, oil wells, water wells, groundwater
conditions and tile drains than the property owner.
19.2 Setbacks from wells
All NASM in Category 3 and 4 should stay back a minimum 90 meters from all
wells (reg 347)
19.3 Depth to bedrock
There should be no land application of CP2 and CM2 where the depth to
bedrock is less than 90 meters.
Table 5 - Risk of potential groundwater contamination
Cracked Karst or Cracked limestone sub soil
There is a problem with land application of biosolids on soils that allow
rapid movement of sludges into the soil. There is far more movement
horizontally and vertically of biosolids materials. Clay soils can also
allow even more rapid movement down into groundwater than sandy soils due to
root whole, pop ups, and worm holes. Research done in Ottawa and elsewhere
in Southern Ontario refutes the risk assumptions in Table 5
There should be restrictions on sludge spreading on these areas
Table 6 Application standards based on risk level
These restrictions are inadequate to be protective since the groundwater
contamination potential table is inaccurate and inadequate. Since
previously, the maximum 5 year application rate of sewage sludge was 8 dry
tonnes per hectare per 5 years to allow 18 dry tonnes per hectare per 24
hours in an area of high groundwater contamination risk is a severe
weakening of the protections that were previously in place.
19.5 Pre-harvest grazing and crop harvesting
The waiting periods are inadequate for both crop grazing and harvesting.
Pathogens are not the only issue. There is also particle size, surfactants,
endocrine disruptors, PCBs, PBDE, etc.
The US requires a 38 month waiting period for sludge amended soils
harvesting root crops. Ontarios waiting periods need to be scientifically
reviewed.
19.6 Winter Application
There should be no winter application of NASM. There is no crop growing in
the winter to take up the nutrient so the nutrient will evaporate into the
air (greenhouse gases) and will run off into surface water in the spring.
Snow covered and frozen land should not be worked
.you cant inject into
frozen ground and you cant incorporate. The soil is frozen. The risk of
contamination at the time of spreading or at the next thaw is very high.
Soil compaction is also an issue.
There should be no winter application of NASM
20.1 Odour
Odour is a form of trespass.
Who makes the odour determination? There needs to be a provincial odour
panel
There should be an odour tribunal in the case of complaints.
21.1 Maximum application rate
The calculation for phosphorus allows for annually 390 kg phosphorus per
hectare more than the crop removes. It is rapidly pushing up the phosphorus
levels in Ontario soils.
Ontario soils are already generally well furnished with phosphorus. This
excessive phosphorus is putting surface water at risk from excess nutrient
and algae blooms
especially from materials that move through tile drains
into surface water and soils that was washed into water in rain and snow
melt events.
Table 8
There is no scientific justification for the maximum allowable metal
concentrations in Table 8. Doubling the maximum amounts of metals that are
naturally occurring in Ontario soils is not protective of crop or soil
quality - and may be impacting wildlife and body burden of certain toxic
metals.
There should be a scientific review of allowing soils to reach these levels
of metals.
Sodium
Salting the fields is the path to destruction of farm soil productivity. It
is historically the reason for the end of agricultural civilizations around
the world. Allowing NASMs- with their higher levels of salts to be land
applied can be having negative consequences to the sustainability of Ontario
agriculture. Soil trends and risks need to be systematically reviewed
before these permissive levels of salting are allowed.
Boron
Boron can be toxic in soils. Instead of a blanket permission to add up to 1
kg of boron the boron levels should be assessed
ALL sources of boron
evaluated and a determination of whether NASM will be allowed should
depend on whether protective
boron levels are being exceeded.
24.0 Record Keeping
Record keeping should be permanent and in storage at MOE offices. NASM
records should be public records available on request or through FOI
25.0 Storage
There should be no field storage of NASM.
Additional Recommendations
All use of NASM on agricultural lands should be reviewed by the local
Medical Officer of Health who may make additional conditions or
requirements
-All such requirements and conditions should be made public
The proposed Nutrient Management Plans and Strategies should be publicly
available at the municipal offices for public inspection or copying
There should be field posting requirements for all pathogenic NASMs. All
fields spread with pathogenic NASMs should have fencing to keep out people
and animals for one year following application.
Signage the fields proposed to be spread with pathogenic sludges should
have a large sign posted two months before application and for one year
after application.
All municipalities in which NASMs are spread should have a municipal
inspector to review the NMP and NM Strategies for compliance and they should
attend all NASM spreading events. Their salary should be provided by the
generators of NASMs.
Farmers who accept NASM on their farmlands should be indemnified by the
generator and hauler.
Review and Appeal provisions:
The NMA should have a review and appeal process. Since the people who write
up the Nutrient Management Plan may not be aware of all the features of the
landscape and history of landuse (abandoned wells, groundwater
Sensitive receptors
There needs to be a review and complaint mechanism to deal with problems
related to land application health problems, odour, and environmental
issues.
