A. (2) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality
to Ceriodaphnia dubia at an effluent concentration of 90%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the
"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent
versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February
1998) or subsequent versions. The tests will be performed during the months of March, June,
September, and December. Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
below the permit limit, then multiple -concentration testing shall be performed at a minimum, in
each of the two following months as described in "North Carolina Phase II Chronic Whole
Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are specified
in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or
subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the months in which tests were performed. If reporting pass/fail results using
the parameter code TGP3B, DWQ Form AT-1 (original) is sent to the below address. If reporting Chronic
Value results using the parameter code THP3B, DWQ Form AT-3 (original) is to be sent to the following
address:
Attention: NC DENR / DWQ / Environmental Sciences Section
1621 Mail Service Center
Raleigh, Forth Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than
30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine
is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form
indicating the facility name, permit number, pipe number, county, and the month/year of the report with the
notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental
Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will
be required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified
to include alternate monitoring requirements or limits.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT
Forms submitted. '
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid
test and will require immediate follow-up testing to be completed no later than the last day of the month following the
month of the initial monitoring.

Subject: RE: tox test for NCO038822
That looks good. It doesn't matter to me which months are chosen for testing, however, I know they did run a WET test
already in the month of March (if that has any bearing on the decision).
Don't forget to add the WET Testing to the Table.

AMMONIA TOXICITYPOLICY
In 1990 the EPA decreed that each delegated State develop controls on ammonia as a toxicant (after
years of considering it to be primarily an oxygen -consuming waste). North Carolina uses two instream
criteria adopted from EPA research:
• Summer instream criteria= 1.0 mg/L
• Winter instream criteria = 1.8 mg/L
(Note: These are called "criteria" because standards have not been formally adopted for non -trout
classified waters in North Carolina.)
In order to evaluate whether the discharge has the potential to cause instream toxicity, the allowable
effluent concentrations of ammonia (summer and winter) are calculated with the mass balance equation
(using the IWC Excel Spreadsheet in Appendix A). Both summer 7Q10 and winter 7Q10 are used in
the equation. Ammonia is the only toxicant that is limited differently for summer and winter seasons.
An upstream concentration of 0.22 mg/L is assumed. If the allowable concentration is greater than 35
mg/L, no limit should be imposed. If the allowable concentration is less than 35 mg/L, potential toxicity
may be occurring. If there was already an existing ammonia limit based on oxygen -consumption, the
more stringent ammonia limit should be placed in the permit.
If the mass balance calculation indicates the need for ammonia limits, it is Division policy to set limits
no more stringent than 2 mg/L (summer) and 4 mg/L (winter) for small discharges (those less than 1.0
MGD). This is based on the Division's determination of BAT (best -available technology) for these
types of facilities. Therefore, even if the calculation for a winter ammonia limit yields a 3.5 mg/L result,
a 4 mg/L limit would be given.
For any new or expanded flow, an ammonia limit should be given
j However, for existing flows where
potential toxicity may be occ e permit holder shoul e given the option to have the ammonia
limit(s) placed in their permit or to have a quarterly chronic, WET test, pass/fail at the instream waste
concentration using Ceriodaphnia as the test organism. Many times the facility will need a compliance
schedule to be placed in the permit in order for renovations to be made at the site. Such schedules
should be coordinated with the regional office and the permit holder but should not exceed three years.

Re: Central Care Inc. NPDES Permit # NCO038822
139 Apex Lane, Mount Airy, Surry County, NC
Request for Modification of Discharge Limits
GeoSci Project #09.109
Dear Mssrs. Weaver and Tedder:
RECEIVED
M AY 15 2009
DENR - WATER QUALITY
POINT SOURCE BRANCH
On behalf of Central Care Inc. (CCI) of Mount Airy, Geoscience and Technology, P.A. (GeoSci)
is pleased to present this request for a modification to NPDES Permit # NC0038822. This
request is in response to NOV(s) issued from the WSRO related to NH3 discharge limit
exceedances and is based on various correspondences with Mr. Tedder.
Mr. Tedder indicated that "in lieu of ammonia limits, the facility may choose to sample for
toxicity using a chronic WET test, pass/fail at 90% using Ceriodaphnia as the test
organism." Furthermore, if compliance with Chronic Toxicity (CT) testing could be
demonstrated, then a request would be justified to rescind the current effluent limits for NH3 as
indicated in Section A.1 of the current permit and replace them with the Pass/Fail limits for
Chronic Toxicity.

GeoSci contacted Jim Chesire at Research & Analytical Laboratories (R&A) in Kernersville, NC
and requested that they perform two CT tests on the effluent. R&A operates the wastewater
system at this facility and performs the required effluent analyses. R&A performed CT testing on
March 3 and March 9, 2009 and again on March 31 and April 3, 2009. The analyses results
indicated `PASS' for both tests. Copies of the certified laboratory analyses results and
accompanying Chain of Custody documents are attached.
Based on these results, Central Care Inc. requests that the NH3 effluent limits contained in the
current discharge permit be replaced by Chronic Toxicity testing.
GeoSci and Central Care, Inc. appreciate your time in considering this request. Please contact me
at 336.896.1300 or via email: [e-mail] if you have any questions or comments about our
plans or the project in general
With Best Regards,
Geoscience and Technology, P.A.

Charles,
I hope you are feeling better. I am working from home recovering from hip replacement surgery
on 4/20. It is OK but being home all day is driving me crazy.
Thanks for the permit. I will be sending a request in the next couple of days to change the
NH3 effluent limitation to Chronic Tox. I am sending a draft to my office for peer review
today and should be ready to send out tomorrow or Friday. Steve Tedder suggested that we
perform two CT's and they both passed.
Thanks for your help. Stay well.
Sincerely,
Peter DeVries

central Care tox test
subject: [Fwd: Re: central Care]
From: Steve Tedder <[e-mail]>
Date: Tue, 17 Mar 2009 07:59:20 -0400
To: Charles weaver <[e-mail]>
Morning Charles,
This is just a heads up. As you know Central Care in Surry county (NC0038822) has
had NH3 violations for the past
12 plus months.
They have a long history with NH3 problems. After pulling out the old zero flow
policies I suggested to them that
they run a tox test just to see the results. in looking at the NH3 values I thought
they had a chance to pass the
test and they did. I've told them to run one more and if it passes to request a
minor permit mod to drop the NH3
limit and include a tox.
sure wish I had thought of this a year ago cause it sure would have saved them a
ton of money.
Tedder' maybe we are on the right track.

Thats great news. Personally I'd repeat the test one more time to be sure. I'd
repeat it asap and if the second one
passes I would then send in a letter to the Permitting unit in Raleigh (attn.
charles weaver) indicating that the
permitee is requesting a minor permit modification and request the tox requirement
in place of the NH3 limit. Cc me
on the letter.
I will be taking this into consideration on any additional NH3 permit exceedences
until we can get the permit
resolved.

in closed systems. Avoid contact with vapors and/or mists from head space of containers. Refer to
Section 10 for proper personal protective gear. Do not store in steel or stainless steel containers.
Section 8. Disposal Considerations
Waste Do Not Dump Into Any Sewers, On The Ground, Or Int3 Any Body Of Water. Pesticide wastes are acutely
Information hazardous. Improper disposal of excess pesticide spray mixture, or rinsate is a violation of Federal Law. If
these wastes cannot be disposed of by use according to label instructions, contact your State Pesticide or
Environmental Control Agency, or the Hazardous Waste representative at the nearest EPA Regional Office for
guidance. Do not reuse empty container. Triple rinse the container (or equivalent). Then offer for recycling or
reconditioning, or puncture and dispose of in a sanitary landfill, or by other procedures approved by state and
local authorities. All disposal methods must be in compliance with all Federal, State and Local laws and
regulations. Regulations may vary in different locations. Waste characterizations and compliance with
applicable laws are the responsibility solely of the waste generator. SOUTHEASTERN LABORATORIES,

container tightly closed. Keep From Freezing.
Section 10. Exposure Controls, Personal Protection
Engineering Controls Good general ventilation should be sufficient for most conditions. Use local exhaust ventilation with a
minimum capture velocity of 150 f /min. (45 m/min.) atthe point of mist evolution. Eyewash and safety
shower should be immediately available.
Personal Protection
Eyes Safety Goggles. Certain conditions may require the use of a Face Shield. Eyewear must be
compatible with respiratory protection system employed.
Body Long sleeved, body covering clothing Rubber apron. Certain conditions may require the use of
Full -body Suit and/or Boots.
Respiratory A respiratory protection program meeting OSHA 1910.134 and ANSI Z88.2 requirements must be
followed whenever workplace conditions warrant a respirator's use. Good general ventilation should
be sufficient for most conditions Wear a MSHA/NIOSH approved respirator suitable for
concentrations encountered where exposure limits are exceeded. Air -purifying respirators should be
equipped with organic vapor cartridges and dust and mist filters.
Hands Use Impervious Full-length Gloves such as Butyl Rubber, Neoprene or Nitrile. Gloves should be
removed and replaced immediately if there is any indication of degradation or chemical
breakthrough. Rinse and remove gloves immediately after use. Wash hands with soap and water.

sunk in. They have had certification staff out for TA and have contacted three
`consultants to evaluate options. Looking at some new technology for bugs as well as

that does not look like it will happen in the near future.
;,Their history does look bad and they have been assessed about every month for the

Now that tie to city is out of the question, they know they will have to travel a
,'different path. If they can make a decision and have a timeline, I'd be willing to
do soc .
