Hi Ken, 011�
Here are the comments from Barry. We also recommend that you also run the plans by Shelton Sullivan
since we have a pending enforcern&se concerning this facility. Danny said that in the cover letter
with the ATC we should tell Hanson that we will reinspect the reparian buffer near the creek to
determine if additional plantings may be necessary, if the vegetation was impacted. He said either he or
Shelton can help you with the language for this.

This looks okay to me, but I'd ask them why the ERMA linerisnot anchored at the top
of the berm. I think that standard construction practice is to anchor top and bottom to
prevent liner slippage. I put the drawings back in your mailbox.

1-li Judy,
Re: NOV for Hanson Crabtree Quarry, NCG020052
a) I received the revised drawings for the Hanson holding pond yesterday. They have addressed all
my concerns from an additional information request, and I'm ok with issuing an ATC based on the
talcs I received October 24, 2007, and on the revised drawings I received yesterday.
b) RRO's July 6, 2007, NOV letter lists the required response from Hanson as, "3. Your staff has
indicated that the company intends to build a concrete basin to replace the current earthen basin at
the rock crusher. All additional wastewater treatement facilities and equipment must receive an
Authorization to Construct prior to installation as outlined in Part II Secretion A of the permit.
Please call Ken Pickle at [phone] extension 584 concerning questions about obtaining
Authorization to Construct." Also, item 2 of the required responses in the NOV letter requires float
controls and telemetry alarms.
c) I have met with those folks, had a couple of phone conversations with them, and on January 7,
2008, requested additional information based on the October 24, 2007 original submital. The
current ATC submittal does not propose concrete construction as initially envisioned, but rather a
re -working of the current earthen pond with a new reinforced EPDM liner, and dual pumps (one as
a back up) with float controls and telemetry alarms, all under the stamp and signature of their
in-house PE. It all looks ok to me. I'm prepared to send them an ATC letter for the proposed
system, pending your ok/input.
d) Yesterday's submittal shows you on distribution, so l presume you have.a copy of the latest
drawings. Let me know if you don't.
e) Are you OK with issuing the ATC? Can I proceed?

Discharge of untreated Process Wastewater
NPDES Permit Certificate of Coverage NCG020052
Wake County
Dear Mr. Williams:
On July 2, 2007 and July 5, 2007, Judy Garrett of the Raleigh Regional Office conducted a compliance
inspection due to a citizen's complaint of a white plume observed in Crabtree Creek below the Quarry on
Saturday, June 30, 2007, Ken Pickle of the DWQ Central Office accompanied Judy Garrett during the
July 5, 2007 site visit. This letter concerns a discharge of untreated process wastewater from a holding
pond breach which reportedly occurred on June 30, 2007. It also transmits the results of the compliance
inspection of the facility.
Judy Garrett visited the facility with Land Quality Inspectors, on July 2, 2007. It was found that on Friday
June 29, 2007, the holding pond -berm at the rock crusher failed and about 50,000 gallons of untreated
water and solids was discharged to Crabtree Creek after Hanson staff left the facility. It was reported that
the transfer pump in this pond was turned off and it had no float control. As a result, the berm failed
during the approximately 1 inch of rain that fell that night. This failure was found by Hanson staff at about
6 am on June 30, 2007. The berm was temporarily repaired, but no report of the discharge overflow was
made to DWQ. Additionally, a large deposit of wastewater solids was observed along the bank of
Crabtree Creek,
During this same site visit on July 2, 2007, evidence of solids discharge was observed from the piles of
material that had been removed from the ponds on the south side of Crabtree Creek. This material was
piled about 15-20 feet high beside the ponds, on the creek side. A previously constructed sediment basin
was full of solids and solids were traced down the creek bank to the creek.
During the July 5, 2007 site inspection, DWQ noted many deficiencies in the company's compliance with
permit requirements. A Stormwater Best Management Practices Plan is required which outlines the
BMPs that are in place to prevent contaminants form entering surface water via stormwater. The plan
(T)Must be improved to include all requirements of Part III Section A. of the permit. The plan must also
include Preventive Maintenance and Good Housekeeping Practices as required by this section. No
Omo�itoring_has been conducted on stormwater discharges, either analytical or qualitative as required by
Part III, Section B of the permit. All deficiencies are violations of Part III of the Permit.
The DMRs for the wastewater outfall 001 were reviewed and found to be complete.

Re: Notice of Violation, NOV-2007-PC-0472, Hanson Crabtree Quarry, Basin
Discharge Design
Dear Mr. Pickle:
n f� SuG 711-0 4)
We are submitting for your review the proposed design for the Crabtree Quarry storm
water basin. The design includes a clay wall structure lined with EPDM rubber (ethylene,
propylene, diene monomer) commonly referred to as rubber roofing, and covered with.
washed crushed stone. Site personnel have implemented a number of storm water
control and diversion measures that have greatly reduced the drainage area for this
basin. Our design engineers have completed a design capable of controlling a 25 year,
24 hour storm event.
An integral part of the design is the use of a dry prime, automatic self priming auto start,
high head, two float assembly control, approximately 3200 gallon per minute, 8" diesel
pump. The float system will allow the pump to operate independently, 24 hours per day,
on a precipitation dependent basis. The 3200 gallon per minute pump will be capable of
removing water from the basin and discharging to the quarry pit during a 25 year, 24
hour storm event. An identical, in specifications, back up pump will be included pursuant
to the Division of Water Quality request. The pumps will incorporate a dial alert system
for after hours monitoring and an additional fuel tank. Operationally, the processing
plant will continue to function as before with regard to the flow of water during working
hours.
Subject to your approval of this design we will acquire the pumps. We estimate the
basin construction to take approximately 3 to 4 days with work performed as much as
possible during a dry weather. Work on the basin construction will begin as soon as
weather permits.

I've looked at the two drawings dated 11-21-07 depicting proposed construction for
the detention basin at the Crabtree Quarry. I apologize for my delay reviewing
them. I cannot issue an Authorization to Construct without further information or
discussion or drawing revisions on the following points.
a) The backslope of the proposed basin scales to a slope of approximately 1-1/2 : 1.
I obtained this value by comparing the section elevations of the berm (-245 top and
225 toe, or 20' fall) and the plan view of the backslope at approximately 30' wide.
Absent any corroborating soils information I'm not confident that such a slope
provides long term soil stability of the backslope of the basin. Please address this ✓
in a resubmittal.
b) The EPDM liner is identified as "Non -reinforced". Absent any corroborating
experience with this material, it seems to me that a reinforced membrane would be
preferable. The resistance of the liner to puncture and its dimensional stability
could be critical to the long term integrity of the earthen construction detention
basin. Please provide a scrim -reinforced liner. Also please provid liner specs that
7� establish the long term UV resistance in the liner material.
c) The typical sump detail confuses me with respect to the pump on and pump off
elevations. First, it seems they have been mistakenly reversed with the pump off
elevation erroneously set above the pump on elevation. Second, even if this reversal
is corrected, these are very large pumps, and with only one foot of separation
between the pump on and pump off elevation, you may have large motors with very
frequent on -off cycles. Perhaps this is standard practice in the industry, but it
runs counter to my experience in other applications. Please clarify for me the
intended pump operating cycles.
ld) I'm confused about the upslope limit of the detention basin. On the emergency
spillway section I see a weir elevation of 243.50', but I see no continuation of the
berm on the upslope side. Is it your intent that at maximum water elevation the
basin will spread upslope, under the operating equipment?
e) On Sheet 2, the Site Map, I see a dark feature that runs approximately 300' along
the top of bank. But I see no corresponding representation on the part plan of the
detention basin area, nor any detail of this feature. What is it? Please make the
two drawings consistent with each other.
f) I need three copies of the plans.
g) All this work must be the work product of a PE, or under his specific direction-.
This fact is attested to by the placing of the responsible PE's seal and signature on
the drawings. Please provide stamped, signed drawings.

In response to your e-mail correspondence dated January 7, 2008,.please find enclosed three
copies of the revised plans for the containment pond for the Crabtree Quarry. The following
comments and revisions to the plan were prepared by Mr. Alien King, a Lehigh Hanson employee
and professional engineer licensed in the State of North Carolina.
Comments and revisions to the plans are as follows:
A. The slope as shown on the Section A -A on sheet #1 (--245 top and 225 toe) is the
existing slope from the plant down to Crabtree Creek. The portion of the slope from
elevation 225 to 240 has been in place since the construction of the plant approximately
in the late 1950's. This area has been constructed of structural fill, rock and rip -rap. Over
✓ the course of the years this slope has established with volunteer vegetation. To modify
this slope would require permitting from the Corp of Engineers and Division of Water
Quality. The back slope of the basin is under the plant area and, therefore, not possible
to change.
The interior slope of the basin was designed utilizing the grade elevations as surveyed.
As a rule of thumb, for embankment stability, the sum of the horizontal component of the
internal & external slopes should equal 5 or greater (meaning if the interior slope is 2:1
the exterior slope should be 3:1 or greater). Using the existing exterior slope estimated by
Mr. Pickle (1.5:1) the interior slope should be constructed at 3.5:1 slope. The details and
plans have been modified to reflect the change in the slopes. As shown, this change
moves the center line of the basin approximately 4 feet towards the plant. This would
make an insignificant change in the volume of the basin.
✓ B. The detail showing the EPDM membrane has been revised to show a reinforced pond
liner membrane 45 mil. thick.
C. The pump float settings have been revised as follows:
Pump On & Pump Off elevation equals 241.0, the emergency Pump Off elevation will be
been set at 243.5.
The float settings are such that the 'pump off' elevation allows for the basin to be
dewatered without the sump being completely drained. The `pump on" elevation has
been set for 241.0.

�..
��:
�' �,
:w `'
,. .
..-� �. �'�
{ fir' �r�
�,l1(
�.'
-ti' ?;

Given the small basin size and the estimated 025 of 11.22 CFS, with these float settings
the pump (capacity is 3500 GPM) will cycle as; basin fill time for 35 minutes and pump
run time for 80 minutes.
The upper "pump off' elevation of 243.5 has been set at the same elevation as the crest
of the emergency spillway. This has been set such that in the event that water surface
elevation of Crabtree Creek rises to the point such that it begins to back flow into the
basin the pumps will be shut off so as to not allow for creek water to be pumped into the
pit. As the creek water level drops, power to the pumps can be restored and pumps
automatically restarted.
D. The upslope limit of the basin terminates at the foundation of the plant structure. Since
the installation of the basin, during large storm water events, water does back up and
spread under the plant. Although the water does back up under the plant the 3500 GPM
capacity pumps keeps this to a minimum.
E. Acknowledged and revised.
We trust that this information is sufficient for your review and approval. Should you have
additional questions feel free to contact me.
Sincerely,
Robert Snyder

Hi Judy,
Re: NOV for Hanson Crabtree Quarry, NCG020052
a) I received the revised drawings for the Hanson holding pond yesterday. They have
addressed all my concerns from an additional information request, and I'm ok with
issuing an ATC based on the calcs I received October 24, 2007, and on the revised
drawings I received yesterday.
b) RRO's July 6, 2007, NOV letter Lists the required response from Hanson as, 113.
Your staff has indicated that the company intends to build a concrete basin to
replace the current earthen basin at the rock crusher. All additional wastewater
treatement facilities and equipment must receive an Authorization to Construct prior
to installation as outlined in Part II Secretion A of the permit. Please call Ken
Pickle at [phone] extension 584 concerning questions about obtaining
Authorization to Construct." Also, item 2 of the required responses in the NOV
letter requires float controls and telemetry alarms.
c) I have met with those folks, had a couple of phone conversations with them, and on
January 7, 2008, requested additional information based on the October 24, 2007
original submital. The current ATC submittal does not propose concrete construction
as initially envisioned, but rather a re -working of the current earthen pond with a
new reinforced EPDM liner, and dual pumps (one as a back up) with float controls and
telemetry alarms, all under the stamp and signature of their in-house PE. It all
looks ok to me. I'm prepared to send them an ATC letter for the proposed system,
pending your ok/input.
d) Yesterday's submittal shows you on distribution, so I presume you have a copy of
the latest drawings. Let me know if you don't.
e) Are you OK with issuing the ATC? Can I proceed?

Dear Mr, Snyder:
The Division of Water Quality (DWQ) received your request to construct a wastewater containment
pond at your Crabtree Quarry on October 24, 2007, and again with revisions on February 11,
2008. You proposed the approved construction in response to the subject NOV. In accordance
with your request, you are authorized to construct the approved containment facilities,_ effective
today. ..-- —. __..— ---------- _ -- - - -- --- ---_
Authorization is hereby granted for the construction and installation of a wastewater containment
system consisting of: a containment pond with compacted earthen berms, EPDM reinforced liners
of 45 mil and 60 mil thickness, a minimum 6" thick stone liner, and an 18" thick riprap liner for
the emergency spillway; 2 diesel driven pumps of approximately _350.0-gpm-.capacity_each_and- with
.
automatic on -off float switches; pump discharge piping; an automatic after hours dial alert
alarm/notification system; and two upslope diversion berms, all in the configuration and location
shown in the approved plans submitted to DWQ. In addition, the EPDM liner must be anchored at
the top of the berm, as well as anchored at the bottom. DWQ staff from the Raleigh Regional
Office will re -inspect the riparian buffer near the creek and containment structure to determine if
additional plantings are necessary to restore affected vegetation.
Construction must be completed no later than November 1, 2008.
You must you notify DWQ's Raleigh Regional Office supervisor, telephone number (919) 791-
4200, at least 48 hours in advance of operation of the finished facilities so that regional office staff
can conduct an in -place inspection prior to operation of the containment pond. Such notification
to the regional supervisor may be made during the normal office hours from 8:00 a.m. until 5:00
p.m, on Monday through Friday, excluding state holidays.
Upon completion of construction, you must submit a certification from the designing professional
engineer certifying that the facilities have been constructed and installed in accordance with this
Authorization to Construct, the approved site plan and details, the submitted narrative description,
and the design calculations. Please mail the engineer's certification to DWQ Stormwater
Permitting Unit, 1617 Mail Service Center, Raleigh, North Carolina 27699-1617. Our
Authorization to Construct is subject to revocation unless the facilities are constructed in
accordance with the approved plans, details, narrative description, and design calculations.

Don,
a) As per our meeting today, I am approving minor revisions to the prior approved
drawings detailing the re -construction of the pond at Hanson Quarry.
b) Those revisions are to be as we discussed in our meeting this morning, as per my
mark-up of your drawing, and as per the faxed revised portions of the drawing you
faxed me today.
c) Due to the time constraints of completing the construction by November 1, and due
to my departure today on vacation, I have agreed to expedite my approval this morning,
and to provide this written approval in advance of stamped Approved drawings. You
have agreed to deliver to me 3 sets of drawings showing the revisions NLT my return
from vacation on Tuesday, October 21, so that I can stamp them 'Approved'.
d) In part, the basis for my approval is that I understand that you will be on -site
during the construction and will implement the minor drawing revisions that we
discussed.

INTERIOR SLOPE FACES) OF THE HORIZONTAL COMPONENT OF THE SLOPE (H:V) SHALL BE EQUAL
TO OR GREATER THAN 5.
IN NO CASE SHALL THE INTERIOR OR EXTERIOR SLOPES BE INSTALLED STEEPER THAN 1.5:1 (H:V)
FOR EROSION CONTROL PURPOSES THE EXTERIOR SLOPE SHALL BE ARMORIZED WITH A LAYER
OF CLASS B RIP -RAP
2. The plan view has been revised to show that the exterior slope of the berm is to be armorized with Class B
rip rap, with a filter fabric under liner. The plan view has been modified to delineate the armorized slope and the
EPDM Liner Installation detail has been noted as such.
Mr. Don S Bright 11, PE will be overseeing the installation of this basin.
We trust that this information is sufficient for your review and approval. Should you have additional questions
feel tree to contact me.
Sincerely,
Allen R. King, PE
