Just to clarify, the impacts and foot print did not change. The revision is the possible addition of a temporary,
single span work bridge over Mark's Creek.
The contractor would utilize the permitted footprint and not create any other buffer or stream impacts.
Brian,
The attached email contains information on the polymer slurry and disposal. Please review and comment.

The splice detail should work fine. Thank you.
Attached is a copy of the polymer slurry disposal plan from Long Foundation Company. He has already sent this

Nice to speak with you yesterday at the meeting. Regarding the request in your letter dated 11/12/07 to change
the splice on the drilled shaft steel, does the attached sketch provide adequate clearance for construction activities
or would it need to be lower?

Chris -
Please see the two attached email messages and the attachments within. I have shared both requests with
DWQ's Mr. Brian Wernn and I am awaiting his feed-back.
The first email contains a request by the contractor to add a temporary work bridge. The existing impacted area
will be utilized and no additional impact area is needed or proposed.
The second email contains information about the disposal of the super mud (synthetic polymer soil stabilizer) that
is used in the slurry mix for the drilled shaft construction.
Let discuss both items further upon your review.

Attn: Mr. Lee Bradley
Re: Bridge over Hwy 64 Wendell Falls Parkway (Bent 1)
Wake County, NC
Dear Mr. Bradley:
As noted on our proposal, it is our intent to dispose of our polymer slurry
once this project is complete into the on-site drainage system.
After the completion of the drilled shafts, the slurry will be mixed with
household bleach at a rate of 1 gallon to every 4,000 gallons of slurry. Once the
slurry has been broken down, all that will remain is acrylate molecules and water.
Please see the attached disposal suggestions from our polymer slurry
supplier, PDSCo. Should you have any questions please contact me.
Sincerely,
Long Foundation Drilling Co.,.

RE: Super Mud (synthetic polymer soil stabilizer) environmental issues,
Tn, response to questions on the environmental impacts of Super Mud we submit the following:
l: Common disvosal practice.
In general we recommend oxidation of, the slurry prior to disposal to break the polymers and
other. ingredients in this product into inert products such as COZ, Hz, and minute traces of
Nitrogen. Super..Ivlud degradation can be accelerated by oxidation with oxidizers such as
hydrogen peroxide (H,OZ) or 5.25% sodium hypochl.orite (household bleach).
'Th,e procedure for usage of household bleach. to degrade the polymer is simple. A 1,:1 ratio of
bleach to Super Mutt is added to the slurry. For example 1. gallon of household bleach is added
to $00 gallons of slurry when the recommended dosage of 400:1 (water:Super Mud) is Used.
This is then mixed well by methods such as reeiretilating pumps attached to the slurry tank or. by
~iuger rotation until the viscous nature; of the slurry is gone.
Hydrogen peroxide may be the preferred oxidant in many applications due to the HZOz degrading
to oxygen and inert water .Unlike bleach, no extra chemicals are added to the water such as
sodium chloride or chlorine. The procedure for usage of hrydrogen peroxide i.s the same with the
exception of dosage. One gallon of household grade H~OZ (3% HZO~ should be added to the
slttny for every S gallons of Super. Mud.
2: Super Mud is environmentally friendly
Super Mud is inert and presents no harm to the cnviroxtm.ent. The volume of. ,pure Super Mud is
approximately: ,
- 40% HZO & emulsifier
- 35% polymer (an inert polyacrylamide polymer similar to polymers used in water and
wastewater as flocculents).
- 25% base oil (light hydrocarbon, contains the idertieal petroleum distillate which is
approved by the F.DA for the productio» of..food contact papers and for the clariFcation
of beet, cane sugar juice, liquor, and by the EP,4 for the treatment of potable water).
The CAS number of~th~ petrolcttm distil.latc in Super Mtttl is UG4742-47-8. Please note that the

used slurry is diluted with water 800:1 (water.:Super Mud). Super Mud slurry isnon-toxic and
r~.on-hazardous and disposal should not present a problem. Ett,cl.osed is a copy of the official
laboratory analysis repor. t on pine Super Mud and a copy of the priority pollutant list content
{United States Environmental Protection Agency, EPA). This priority pollutant Iist indicates that
the up~re, product contai.us some cyanide and copper however please note the following:
A. The priority pollutant list testing was performed on tp ire product. In usage tb.e product is
diluted, 800 part water to one part Super, Mud. During usage the product may undergo further
dilution. Regardless, if. the product is used at nonnal dosage or even at a higher dose the
resulting slurry would meet the very strict EPA drinking water criteria (criteria for, treatment of
water for use as a drinking water source).
B. Jf. Super Mud is disposed as port product, the waste would be classified as non-hazardous
per EPA regulations.
C. There are no TC.LP (Toxic Characteristics >:,eaching Procedure) limits for the small
quantity of Cyanide and Copper fowa.d in the pure product. '1'l~.i.s is a very intensive testing
procedure, required by the EPA, using an acid to determine the potential, of a waste or its
contamin.atiungtonstituents to enter into groundwater. Also enclosed is testing performed on
Super Mud slurry in regards tv the toxicity of this product. From this information it can. be
observed that this product is non-toxic.
3: Collection anal stora e.
When a dr..illed shaft is constructed, the slurry stabilizes the shaft. Qnce the slt.aft has been drilled
to the desired depth and size, concrete is usually placed in the shaft beginning at the bottom. As
the concrete i.s placed the slurry is displace and pumped to a storage tank for reuse on the next
sb.a$. Following completion of th.e project, the slurry is mixed in the tank with th.e oxidants, (if
forced degradation. is specified), and disposed of per site requirements.
4. Super Mud is biodegradable
Enclosed is a copy of a letter from our analytical Iaboratoryry stating the biodegradability potential
For Super Mud. It is felt that tlus product will biodegrade over time to yield invrganie nitrogen.
Tl1is product will also photodegrade if left in. sunlight.
If you have any questions or if we can be o.f assistance please let us know
Best regards,
