1.0 Introduction
' A water quality monitoring program has been established for The Preserve at Jordan Lake Golf
Club. The monitoring program will include monitoring of surface water, pond sediments, and
' ground water. The monitoring plan, based on sound, scientific principles will:
1. Establish a baseline of water and sediment quality prior to construction,
2. Provide data that will establish environmental conditions, thus providing a basis for
measuring compliance with environmental regulations, and
3. Ensure that Integrated Pest Management is functioning properly.
' An adaptation from a model proposed by Madhun and Freed (1990) notes that there are four
basic types of monitoring which can occur: 1) Reconnaissance - periodic observation to disclose
' changes or trends. With IPM employed this is an integral part of this program; 2) Surveillance -
to comply with an enforcement program. Pesticide application licensing programs require record-
keeping which may be monitored at any time. This will be required by law and serves as a record
' of a part of the cultural program; 3) Subjective - spot-checking for broad or open-ended
exploration of problems. A superintendent with training and experience in the golf course
management industry has the background and resources to investigate problems and make
' intelligent decisions; and 4) Objective - to provide data for use in developing or confirming the
results of on-going programs. Monitoring operations at The Preserve at Jordan Lake Golf Club
will focus on maintaining environmental quality and obtaining information on which to make
' adjustments in cultural programs using all of these approaches.
' Results of the Environmental Water Quality monitoring program provide feedback to the golf
course superintendent, and thus provide a useful management tool. For example, the results of the
program are used in determining the correct application rates and timing of pesticides and
fertilizers, and the optimum operation of irrigation programs.
The Environmental Monitoring Program is established in two phases that coincide with golf
' course development. Phase I is during the construction and development phase and immediate
post-development time-frame, and Phase II is the post-development, operational golf course.

2.0 PHASE I: BACKGROUND CONSTRUCTION AND DEVELOPMENT PHASE -
SURFACE WATER, GROUNDWATER, SEDIMENT QUALITY AND MACROBENTHOS
MONITORING.
The goal of Phase I is to establish background surface water, groundwater, sediment quality and
macrobenthos population data at The Preserve at Jordan Lake Golf Club.
2.1. Sample Locations.
Surface Water. Surface water on the property are several unnamed tributaries which
ultimately egress the property to Jordan Lake. Water will be sampled at locations on the
creeks that are described below and shown on attached map (SW means surface water):
Sample Station SW-1, SW-2, & SW-3. Surface water test location at discharge
location
Sample Station SW-4 & SW-5. Surface water test location upstream of project
Obtaining water samples from the same location is important so that comparisons can be
made. Sample stations will be located and permanently marked in the field, identified on
maps, and photographed so that stations are easily located during subsequent sampling
efforts. Data from these sample stations will allow an assessment of the quality of the
water.
Groundwater. Surficial groundwater will be sampled at nine locations that will be
determined by the geologist based on flow directions. Four wells will be up-gradient, and
five wells will be down-gradient of the golf course. Locations will be described once they
are determined, and will be given below and shown on attached map (MW means monitor
well).
Sample Station MW-1 thru MW4 and MW-9 are downgradient
Sample Station MW-5 thru MW-8 are upgradient.
' Groundwater sample stations will be field marked, identified on maps, and photographed.
Data from these sample stations will allow an assessment of the quality of the groundwater
on the site.
' Environmental Monitoring Program Page
Sediment Pond sediment will be sampled from the sediments of three tributaries. The
' location is described below and shown on attached map (S means sediment).
Sample Stations S-1 thru S-3 are downgradient
• Sample Station S-4 thru S-6 are upg[adient to measure sediment that may be
' entering the property.
The sediment samplina station will be impounded during construction. Thus, in
' subsequent sampling phases, the location will be changed from the tributary to the pond
that will be constructed.
' Macrobenthos Sampling for benthic macroinvertebrates will be conducted at four
locations. The location is described below and shown on attached map ( MB means
' macrobenthos ).
Sample Stations MB-1 thru MB-3 are downgradient
Sample Station M13-4 is upgradient
2.2. Sample Frequency. The goal of Phase I is to define conditions at the site.

Surface Water. Surface water samples will be collected three times prior to beginning
Phase H. Depending on the construction schedule, one sample event will be in Winter
(December, January, February), Spring (March, April, May), one in Summer (June, July,
August), and one in Autumn (September, October, November). Should water not be
available on a given sample date, two additional attempts should be made to obtain a
sample within the time period.
Groundwater. Groundwater samples will be collected three times during this phase.
Sediment. Sediment will be collected one time during the spring sample time.
Macrobenthos. Macrobenthos samples will be collected one time prior to any construction
activity in the fall or winter.
This phase of the monitoring program will be converted to Phase II when grassing has been
completed.
2.3. Sample Variables. Surface water, groundwater and sediments will be analyzed for the
variables fisted in Table 1. Macrobenthos parameters are discussed in the following section.
The inclusion of pesticides in the analytes was based on several factors that are detailed in the
Integrated Pest Management plan (in preparation) for The Preserve at Jordan Lake Golf Club.
The primary factors were potential quantity of a chemical that may be used at the club, and the
chemical's mobility, leaching potential, persistence and toxicity based on data in the scientific

literature and computer models. Restrictions have been placed on pesticides and herbicides that
have a high leaching potential; those that have a low to moderate leaching potential will be used
sparingly; and those that will be used most frequently have a very low to no leaching potential and
a rapid degradation time.

14. Field Methods. Variables, container type, preservation and holding times for water samples
' are given in Table 2, and for sediment samples in Table 3.
' Surface Water. A number of variables will be measured on-site, including pH, water
temperature, dissolved oxygen, and specific conductance. pH will be measured with a pH
probe that has been calibrated dust prior to use. Specific conductance will be measured
' with a calibrated specific conductance meter. Dissolved oxygen will be measured with a
dissolved oxygen probe (or by wet chemistry methods) that has been properly calibrated.
Water temperature will be measured with a temperature probe attached to the specific
' conductance meter or the dissolved oxygen meter.
Surface water will be sampled by obtaining 'discrete' grab samples of water. Discrete grab
' samples are taken at a selected location, depth and time, and then analyzed for the
constituents of interest. Water will be collected in sample bottles that face upstream, and
water is transferred to sample containers that include proper preservatives and labels. The
' sample containers are immediately placed in a cooler with ice and are taken to a laboratory
for analysis.
A chain-of-custody program is followed to assure that proper transportation and storage
practices are documented and that the appropriate analyses are being conducted.
A field sampling log of surface water sampling and observations will be maintained. The
log book documents site conditions, including stream water depth, weather conditions,
and field measurements and observations. An example of a page from a field log is given in
Appendix I.
Groundwater. Groundwater elevation is determined for each well on each sampling date.
After measuring water elevation, the standing water in the well is removed, and replaced
by fresh formation water. The quantity of water removed is determined from the well
volume and recharge rate. In general, high-yield wells are purged of three well casing
volumes of water and low-yield wells are pumped to dryness. Each well is purged using a
portable pump or with a Teflon® bailer that is cleaned between well samples. Water is
suitable for sampling when three consecutive measures of water have stable pH,
temperature and specific conductance readings.
Wells are allowed to recharge after purging to allow the system to equilibrate. Depth to
the water table is re-measured, recorded and water samples are extracted. Extraction
occurs with a pump, or a dedicated Teflon® bailer. Water temperature, pH, and specific
conductance are measured in water that will not be used for laboratory analyses. Water
samples are taken and decanted or drained into an appropriate sample container that has

the proper preservatives and is labeled. Samples are transferred from the sample device to
' the sample container in a manner that will minimize turbulence and the loss of volatile
compounds. Samples are immediately placed in a cooler with ice and transported to the
analytical laboratory. Whenever non-dedicated equipment is used, cleaning procedures
outlined by the EPA (1986) will be instituted. Special attention will be given to
thoroughly cleaning samplers, tubing, and other equipment. And, to ensure that the
' sample is not contaminated, blanks will be collected and analyzed.
A chain-of-custody program is followed to assure that proper transportation and storage
practices are documented and that the appropriate analyses are being conducted.
A field sampling log on groundwater sampling and observations will be maintained. The
log book documents site conditions, including water depth, observations, weather
' conditions, and field measurements. An example of a page from a field log is given in
Appendix I.
' Sediment. Sediment will be collected with a gravity type sediment coring device or by
hand. Sampling will occur at three locations around the edge of the creek and will be
composited into one sample in the field. The three samples will be collected from near
shore sediments. The approximate top 10-cm of the sediment will retained and analyzed
for the variables listed in Table 1.
A chain-of-custody program is followed to assure that proper transportation and storage
' practices are documented and that the appropriate analyses are being conducted. A field
sampling log on sediment sampling and observations will be maintained. The log book
documents site conditions, including water depth, sediment texture, observations, and
' weather conditions. An example of a page from a field log is given in Appendix I.
' Macrobenthos. Macro-benthos sampling. Standard qualitative collection methods for
small 1' and 2nd order streams are inappropriate. Therefore, it is recommended that an
abbreviated collection technique be used. This technique is a modification of the standard
' method in which only four samples are collected (rather than ten): one kick net sample,
one sweep net sample, one leaf-pack and "visuals". It is recommended that all organisms
are collected and processed during using this survey type. This collection method is
' referred to in this guidance as a Qual4 technique. A list of all taxa collected, taxa richness
values (total and EPT), EPT abundance and biotic index values should be given for each
sample collected using this method.
' This collection protocol is semi-quantitative. The result is lists of taxa and relative
abundance values (DWQ assigns Rare, Common and Abundant value to 1-2, 3-9 and 10
or more specimens, respectively). One of the primary objectives of semi-qualitative
Turf & Environmental Management Associates, Inc

' Environmental Monitoring Program Page 7
surveys is to make within or between site comparisons and to determine the presence or
t absence of benthic macroinvertebrate species with various tolerances to water pollution.
When conducting these types of surveys, attempts are made to collect as many taxa as
possible in an allotted time period and usually requires some experience to select the most
' productive habitat. A disadvantage of semi-qualitative methods is that no information on
standing crop or biomass can be generated.
' DWQ protocols for processing benthic macroinvertebrate samples are discussed in the
Standard Operating Procedures manual (NCEHNR 1997). Benthic macroinvertebrate
' samples collected by biologists are "picked" and preserved in the field. It is not necessary
to know the total number of organisms from a specific habitat type when qualitative or
semi-qualitative samples are collected. It is only necessary to know if those taxa are
present and if they are rare, common or abundant. Specimens are "picked" from the
sample and preserved in 6 dram vials using 95% ethanol. Larger organisms (dragonflies,
crayfish, Megaloptera) are preserved in larger containers. Standard qualitative collection
' methods will take approximately 1 1/z to 2 hours for a team of three biologists to collect
and Qual-4 collection methods will take approximately one hour per site. Field processing
samples in this fashion minimizes laboratory processing.

2.5. Laboratory Methods The Laboratory used for sample analysis must retain certification by
the Environmental Protection Agency (EPA) or its designated State Agency to conduct chemical
analysis on surface water and drinking water. Certification of the laboratory is maintained by
successful performance of the EPA Water Pollution Study and EPA Water Supply Study. Sample
analyses will follow accepted, standard methods as defined in the laboratories accreditation and
detailed in their Quality Assurance and Quality Control procedures. Sample containers, properly
cleaned and containing the proper preservative, should be supplied by the analytical laboratory.
In cases where standard methods are not available, the Laboratory will execute method
development and follow closely related standard practices, and demonstrate accuracy and
precision of the method with at least a 5-point standard curve, sample spikes, and duplicate
analyses.
' Macrobenthos sampling will be conducted by a certified laboratory based on a list approved by
NC Division of Water Quality.

3.0. PHASE II: SURFACE WATER, GROUNDWATER, AND SEDIMENT QUALITY
' DURING OPERATIONS
The goal of Phase H is to assess the effect of construction and operational activities on surface
water, groundwater and sediment quality.
3.1. Sample Locations.
Surface Water. Surface water will be sampled at the same locations that are described in
Phase I monitoring program.
Groundwater. Groundwater will be sampled at the same locations that are identified in the
Phase I monitoring program.
Sediment. Pond sediment will be sampled at the same locations that are identified in the
Phase I monitoring program.
The Phase I sediment sampling station will be ponded during construction. Thus, in this
phase of the sampling program the location will be changed from the tributary to the pond
that will be constructed.
Macrobenthos. Macrobenthos sampling will occur at the same locations that are identified
in the Phase I monitoring program
Sample locations will be photographed and marked on maps. Data from this sample
station will allow an assessment of the quality of the sediment in the pond.
3.2. Sample Frequency. The goal of Phase H is to monitor surface water, ground water and
sediment quality during operation of the golf course.
Surface water samples will be collected four times per year. One surface sample
will be taken in the Winter, Spring, Summer, and Autumn. Should water not be
available on a given sample date, two additional attempts will be made to obtain a
sample within the time period.
Groundwater samples will be collected four times per year during Winter, Spring,
Summer, and Autumn.
A sediment sample will be collected one time per year at the time of surface water
sampling in the Spring.
Turf & Environmental Management Associates, Inc
Raleigh, North Carolina
I Environmental Monitoring Program Page 12
' Macrobenthos sampling will occur one time per year at stations MB-2, MB-3, &
MB-4 and twice a year at station MB-l. Annual sampling will occur during the
I winter and biannual sampling during winter and summer.
Water quality sampling will be reduced to Spring and Autumn events after three years of
' operation, provided that the no significant detections or changes in water quality have occurred.
The Criteria for Management Response outlines the detections or changes that are significant.
Detections of a pesticide listed in Table 1, will trigger additional analyses as described in Criteria
for Management Response.
r 3.3. Sample Variables . Surface water, groundwater and pond sediments will be analyzed for
the variables listed in Table 1.
3.4. Field Methods. Variables, container type, preservation and holding times for water samples
are given in Table 2, and for sediment samples in Table 3.
' Surface Water. Surface water sampling will follow the protocols outlined in Phase I.
Groundwater. Groundwater sampling will follow the protocols outlined in Phase I.
' Sediment. Sediment will be collected with a gravity type sediment coring device or by
hand. Sampling will occur at three locations around the edge of the pond (sample points
will form a triangle around the center of the pond) and will be composited into one sample
in the field. The three samples will be collected from near shore sediments. The
approximate top 10-cm of the sediment will retained and analyzed for the variables listed
' in Table 1.
Macrobenthos. Sampling will follow the protocols outlined in Phase I.

4.0. DATA, REPORTING, AND RESPONSE CRITERIA
4.1 Data Storage and Reporting
Data generated from this monitoring program will be maintained by the superintendent along with
other course records and data on pesticide and fertilizer use, personnel, and training. The data
from the monitoring report will be available to governmental officials within 20 working days
from the date of sampling.
Monitoring data from field sampling and from laboratory analyses will be entered into a computer
spreadsheet (e.g., QuattroPro, Lotus 1,2,3). Data analyses will be performed with this data set. A
summary of the results of the surface and groundwater and sediment samples, with a list of any
remedial actions that were taken will be kept.
The golf course superintendent will maintain records of cultural activities at the course. Items will
include application schedules of all pesticides and fertilizers applied to the golf course as outlined
in the Pesticide section of this Plan. Information will include the date of application, rate of
application, product used, and specific location where the material was applied. Scouting records
as part of the IPM program will also be kept.
4.2 Data Analysis
Data generated in the monitoring program will be compared to background concentrations and
State surface water and groundwater standards.
Data will also be compared with State water quality criteria and the USEPA pesticide Health
Advisories Limits (HAL's, given in Table 5) that have been reduced by a factor of 0.5. This is a
very conservative factor given that HALs have a margin of safety of 100 to 1000 already built into
the HAL number. In Phase II , concentrations of water and sediment variables will be compared
with background concentrations to determine changes from background conditions. Soils data
will be compared with known requirements for turfgrass and adjustments in the fertilization rates
will be made.
Protection of aquatic life will be evaluated by comparing measured concentrations against LCso
data (Table 5) that have been reduced by a factor of 10. LCso data exist for most of the
chemicals, and the lowest LCso obtained for the pesticide was divided by a correction factor of 10
to obtain a screening criteria (Suter et al., 1989; Warren-Hicks et al., 1989). This is a
conservative factor in that most measured chronic values would be higher than those estimated
from this factor (Suter et al. 1983).

Environmental Monitoring Program Page 14
4.3 Criteria for Management Response
Non pesticide analytes. If concentrations of non-pesticide variables exceed Applicable
State Water Quality Criteria, or if an increasing trend is observed (a statistically significant
trend), or if measured concentrations of nutrients exceed the standard deviation of
background levels by more than two-times, then the media will be resampled and a review
of management practices, site conditions and weather conditions will be implemented to
determine reasons for increased concentrations. The immediate action will also include a
reduction in fertilizer use and/or an increased proportion of slow-release fertilizers.
Following the review cited above, these immediate restrictions may be lifted or modified,
as appropriate. Records of all actions taken will be maintained by the superintendent.

Pesticide analytes. If a pesticide listed in Table 1 is' detected in samples at concentrations
below a toxicologically significant level as determined by the USEPA Health Advisories
Limits (HAL x 0.5) or by the aquatic toxicity as measured by LC5o x 0. 1, whichever is
lower, the following responses will result:
1. The sample station, from which the exceedance was obtained, will be resampled
and reanalyzed for the pesticide.
2. Further testing will be required for an additional suite of pesticides ('secondary
level'). A list of secondary pesticides is given is Table 4. Pesticides were included
in this second tier based on the results of the Tier 1 analysis.
3. A review of the use, weather conditions after its application, and possible
alternative control measures will be made and a decision made on the continued
use of the s ecific roblem esticide.

If a pesticide listed in Table 1 is detected in samples at a concentration above a toxicologically
significant level as determined by the USEPA Health Advisories Limits (HAL x 0.5) or by the
aquatic toxicity as measured by LC5o x 0. 1, whichever is lower, the following responses will
result:
1. The pesticide will be immediately removed from the list of recommended
pesticides for use on the golf course, and its use will be terminated.
2. Further testing will be required for an additional suite of pesticides ('secondary
level). A list of secondary pesticides is given is Table 4.
3. The sample station, from which the exceedance was obtained, will be resampled
twice and reanalyzed for the pesticide. Should subsequent resampling and analysis
indicate concentrations below HAL's, the golf course may reinstate the pesticide
on the list of recommended pesticides.
4. If a pesticide listed in Table 1 is detected in samples at a concentration above a
toxicologically significant level as determined by the USEPA Health Advisories
Limit (HAL x 0.5) or by the aquatic toxicity as measured by LC50 x 0.1, whichever
is lower, water samples from the drinking water wells of the most immediate
property owners downgradient will also be analyzed for the contaminant. Should
the material be detected at a level above that as stated above, The Preserve at
Jordan Lake Golf Club will be responsible for appropriate remediation. This could
include providing bottled drinking water and re-sampling of the wells until the
contaminant level drops or having new wells installed for the property owners.
Criteria for management response are summarized in Table 5.

5.0. FIELD QUALITY CONTROL AND GENERAL WATER AND SEDUAENT
SAMPLING CONSIDERATIONS.
The field quality assurance program is a systematic process which, together with the laboratory
quality assurance programs, ensures a specified degree of confidence in the data collected for an
environmental survey. The field quality assurance program involves a series of steps, procedures
and practices which are described below.
5.1. General Measures.
a. All equipment, apparatus and instruments should be kept clean and in good
working condition.
b. Records should be kept of all repairs to the instruments and apparatus and of any
irregular incidents or experiences which may affect the measures taken.
C. It is essential that standardized and approved methodologies be used by field
personnel.
d. Macrobenthos sampling by the certified laboratory should follow the criteria as
outlined in the NC Division of Water Quality Standard Operating Procedures
manual.
5.2. Prevention of Sample Contamination . The quality of data generated in a laboratory
depends primarily on the integrity of the samples that arrive at the laboratory, Consequently, the
field personnel must take appropriate measures to protect samples from deterioration and
contamination.
a. Field measurements should always be made on a separate sub-sample, which is
then discarded once the measurements have been made. They should never be
made on the same water sample which is returned to the analytical laboratory for
chemical analysis.
b. Sample bottles, new or used, must be cleaned according to recommended
procedures.
C. Only the recommended type of sample bottle for each parameter should be used.
d. Water sample bottles should be employed for water samples only.
e. Recommended preservation methods must be used. All preservatives must be of
an analytical grade.
f. Solvent-rinsed Teflon liners can be used to prevent contamination from the bottle
caps of water samples which are to be analyzed for organic compounds.
g. The inner portion of sample bottles and caps should not be touched with bare
hands, gloves, mitts, etc.
h. Sample bottles must be kept in a clean environment, away from dust, dirt, fumes,
and grime. Vehicle cleanliness is important.
Turf & Environmental Management Associates, Inc
Raleigh, North Carolina
Environmental Monitoring Program Page 18
i. All foreign and especially metal objects must be kept out of contact with acids and
water samples. Petroleum products and exhaust fumes should be kept away from
samples.
j. Specific conductance should never be measured in sample water that was first used
for pH measurements. Potassium chloride diffusing from the pH probe alters the
conductivity of the sample.
k. Samples must never be permitted to stand in the sun; they should be stored in an
ice chest.
1. Samples must be shipped to the laboratory without delay.
M. The sample collector should keep their hands clean and refrain from smoking
while working with water samples.
n. Samplers must wear latex gloves.
' 5.3. Field Quality Control . Quality control is an essential element of a field quality assurance
program. In addition to standardized field procedures, field quality control requires the
' submission of samples to check contamination, sample containers, or any equipment that is used
in sample collection or handling, and to detect other systematic and random errors occurring from
the time of sampling to the time of analysis. Replicate samples must also be collected to check the
' reproducibility of the sampling. The timing and the frequency of equipment blanks, duplicate, and
replicate samples are listed in Table 6.
' Equipment Blanks. An equipment blank is prepared in the field at the end of each day's
sampling; and one equipment rinsate blank per water medium per day is prepared. An
equipment blank is prepared by filling appropriate sample bottles with rinsate from the
' final cleaning of non-dedicated, sample equipment, and transporting them to the laboratory
in the same manner as the water samples for analysis.
' Duplicates. Duplicate samples (splits) are obtained by dividing one sample into two sub-
samples. One sample in every ten water samples is split. Splits are done periodically to
' obtain the magnitude of errors owing to contamination, random and systematic errors, and
any other variables which are introduced from the time of sampling until the samples arrive
at the laboratory.
' Replicates. Two samples are taken simultaneously in a given location. The samples are
taken to measure the cross-sectional variations in the concentration of the parameters of
' interest in the system. One water sample per quarter will be replicated.

Dear Mr. Dorney:
4( 1
MAY 0 4 2004

I am writing on behalf of Blugreen Corp. to respond to the items as outlined in the above-
referenced letter. Also, a revised monitoring report has been prepared and is attached.
1. Phase II
a. The November TSS data are missing. Please address this issue.
TSS data were not collected by the Aqua Tech Environmental Laboratories,
Inc. (ATEL) in November 2003. As discussed below, this is one of a number
of sampling and analysis omissions by ATEL. Bluegreen has not received
satisfactory explanation of these omissions from ATEL. Due to ATEL's
failure to fully implement the monitoring protocols, Bluegreen has terminated
its relationship with ATEL and is currently negotiating with Environment 1,
Inc. of Greenville, North Carolina, to assume the responsibility for the
monitoring program. Additionally, Environmental Golf Concepts has been
retained to collate and analyze the data and generate the required reports. This
restructuring of the oversight of the monitoring program will ensure that the
requirements of the 401 certification are met.
b. On Table 1, the footnote states "Note: no DO-Mar, Jun, Oct and Nov ".
Please elaborate and explain the missing data.
Dissolved oxygen data were not collected by ATEL as required by the
monitoring protocol.
C. Data on dissolved oxygen, ammonia nitrogen and TKN are missing. Please
address this issue.

Golf Course and Environmental Specialists
2009 Longwood Drive
Raleigh, NC 27612
919.846.5634 - voice or fax • 919.906.1324 - cell
As noted above, DO data was not collected by ATEL and ammonia-N and
TKN were not determined by ATEL for the water samples collected even
though specified in the monitoring protocol.
d. The subsequent sheets of Table I and Table 2 do not have a first column that
describes the representative sample rows. Please modify the table
accordingly.
New data tables have addressed this issue.
e. The macrobenthos analysis refers to Stream 1, Stream 2, etc. while the
monitoring plan refers to MB 1, MB 2, etc. Please clarify this issue in your
written response.
MB sample designations are identical to the Stream sample designations.
f. The monitoring plan requires sediment samples. Please provide these data or
discuss why they are not available. Please clarify this issue in your written
response.
No sediment samples were collected for analysis by ATEL as required by the
monitoring protocol.
g. Please address the elevated levels of total P, ortho P, Nitrate, chlorophyll a
and turbidity for SW2 in June of 2003. Also address what remedial actions (if
any) need to be taken to resolve this issue.
Nitrate, chlorophyll a and turbidity levels in SW2 were somewhat higher than
previously observed, but still fell within state water quality standards and
acceptable statistical ranges. We do not have an explanation for these
elevations, which did not recur in subsequent sampling. Total P and Ortho P
were not elevated in June of 2003.
h. Coliform data should also be presented as geometric means in addition to
averages and standard deviations.
Coliform data have been transformed and expressed as a geometric mean
across all sample locations for each sampling date (see Tables and Figures in
revised report).
2. Phase I
a. The following data appear to be missing from this monitoring phase-Ammonia
nitrogen, TKN, chlorophyll a, fecal coliform and one set of pesticide data
(only two sets provided rather than the three that are required). Please
provide these data or discuss why they are not available.
Ammonia N, TKN, chlorophyll a, fecal coliform analyses of surface water
samples were not performed by ATEL as required by the monitoring protocol.

2009 Longwood Drive
Raleigh, NC 27612
919.846.5634 - voice or fax - 919.906.1324 - cell
Similarly, pesticide analyses were not performed on one set of samples by
ATEL.
b. The subsequent sheets of Table 1 and Table 2 do not have a first column that
describes the representative sample rows. Please modify the table
accordingly.
This issue has been addressed on the new data tables.
C. Groundwater-Only two samples appear to have been taken rather than the
three that were required. Please provide these data or discuss why they are
not available.
Both 2001 and 2002 were significant drought years. ATEL has indicated that
it was unable to perform surface water and groundwater sampling on
numerous occasions during these years due to drought conditions.
d. Macrobenthos data-Why was stream number 3 not sampled?
Again, due to drought conditions, ATEL claims that it was unable to perform
the required sampling.
e. The monitoring plan requires sediment samples. Please provide these data or
discuss why they are not available.
ATEL failed to follow the protocol and collect sediment samples for analysis.
3. Overall issues related to the report
a. Please consolidate the water chemistry data into graphs (Y axis for
concentration and X axis for time) so we can more readily examine the data
for trends. The data tables should continue to be provided.
The data have been reorganized by sample location and new tables have been
included. The data have also been charted for each sample location for each
analysis over time. A statistical mean +/- 2SD line is included on the charts.
b. Please discuss any data that are greater than the standards or guidelines in
both Phase I and Phase II of the monitoring. Please also address any
remedial actions needed to address these exceedances.
Each analysis of concern will be addressed separately as follows:
SWl Fecal coliform counts for Jun, 2003 and Oct, 2003 - This is the major
stream below the detention pond at the south end of the property. During low flow
any accumulation of organic matter or feces from birds or mammals frequenting the
stream could cause his elevation. Fecal coliform counts for Nov, 2003 and Mar, 2004
were well below the acceptable limit. Additionally, the mean fecal coliform count
across all sample locations for Jun, 2003 and Oct, 2003 was below the acceptable
limit.

919.846.5634 - voice or fax • 919.906.1324 - cell
SWl Turbidity for Mar, 2001 - As noted below, at the time of this sampling
event, this stream was showing increased turbidity at the point of entry onto the
property. The turbidity levels at this sampling location were considerably lower than
at the upstream location. However, construction activity on the property may have
contributed to an increase in turbidity in this time frame.
SW4 Turbidity for Mar, 2001 - SW4 is at the point where the main stream
enters the property from the north. Erosion from upstream was probably a factor.
SW5 Turbidity for Mar, 2004 - This site is near an area where active
development is occurring. There could have been some turbidity increase associated
with land disturbance prior to the sampling date. All other sampling data from this
location have not shown problems. This site will be examined to determine the reason
for this increase.
Dissolved oxygen readings for Mar, 2004 - All readings at the site were
exceptionally low and inconsistent with prior and subsequent data and expected field
conditions. The most likely explanation is that ATEL had a faulty sensor on its DO
meter.
MW3 TDS level for Oct, 2001 - This was the initial reading after the well was
installed. It was only slightly elevated above the acceptable limit of 500 mg/1(reading
of 560 mg/1). All subsequent samples have been below 100 mg/l.
C. Macrobenthos data-Who collected and identified the aquatic insect samples?
The monitoringplan requires a DWQ-certified lab. Please address this
matter in your written response.
ATEL's report for the macrobenthos data did not specify who collected the
samples and analyzed the data in October 2000 and March 2001. MACTEC of
Charlotte, North Carolina, collected and analyzed the data for 2003.
d. Macrobenthos data-There appears to have been a decline in macrobenthos
numbers, taxa number, Dominants in Common and EPT taxa in streams I and
4 from Phase I to Phase II. Please address this issue in your written response
and discuss what remedial actions (if any) you plan to take to address this
issue.
According to the macrobenthos sampling reports for 2000 and 2001 supplied
by ATEL, the bioclassifications for the streams were a concern from the first
sampling. According to a communication with Ms. Patricia MacPherson,
NCDNER, the streams sampled were so small that NC state biologists would
not apply a bioclassification to them. They indicated they are currently
developing criteria to help assess small, first-order streams such as the ones
sampled for this project. Based on this information, any change in stream flow

could have a dramatic impact on macrobenthos numbers, taxa numbers and/or
dominant common or EPT species. The drought conditions during 2001 and
2002 certainly impacted the ability of the laboratory to sample surface and
groundwater and low stream flows could have had an exceptionally
detrimental effect on stream biota.
If you have any questions or concerns about any aspect of the responses to your letter or the
revised monitoring report please do not hesitate to contact me.

Introduction
The Section 401 Water Quality Certification issued on August 9, 2000, by the North Carolina
Division of Water Quality (DWQ) to Bluegreen Corporation (Bluegreen) for the development of
The Preserve at Jordan Lake (the Project) required Bluegreen to implement an environmental
monitoring plan for the Project and to submit an annual monitoring report to DWQ. The
required environmental monitoring plan was prepared for Bluegreen by Turf & Environmental
Management Associates, Inc. This report summarizes the results of the environmental
monitoring program for 2003, which was the first year that Phase II (post-development) of the
monitoring program was implemented. In addition, Appendix A of the report summarizes and
presents data collected in previous years pursuant to Phase I of the environmental monitoring
program and Appendix B presents trend analysis data through the most current monitoring.
The required environmental monitoring was performed under the direction of Aqua Tech
Environmental Labs, Inc., Sanford, NC. Portions of the sample analyses were outsourced to
various subcontractors for specific components of the testing.
Data are presented in table format for specific parameters tested. Statistical analysis included
comparisons using standard water quality criteria testing which compared individual values with
the mean plus or minus two standard deviations.
Aquatic macroinvertebrate data were evaluated for EPT taxa and the streams categorized
according to DWQ criteria for flowing streams in the Piedmont as follows:
Metric Range
EPT Taxa Richness >27
21-27
14-21

Water Quality Data
Surface water and groundwater quality monitoring data for 2003 are presented in Tables land 2,
respectively. Surface water quality was sampled four times. Fecal coliform concentrations were
low in the Spring, peaked in the Summer and returned to low levels in the Fall with the exception
of the October sampling for the SW1 location. All values were within the mean +/- 2SD range
for each sampling date. Some seasonal variability is to be expected and this was noted. The high
values at SW 1 for June and October would indicate that an anaerobic condition may have existed
at this location or that animal droppings may have contributed to the high count. Ortho-P levels
were low ranging from 0.01 to a high of 0.07 mg/l. Turbidity values were low, as were Total
Dissolved Solids (TDS) values, which ranged from 64 to 160 mg/l. Temperatures were
consistent across sample locations showing only temporal variability. pH was more alkaline in
the March samples but all values were within the acceptable mean +/- 2SD range and only
slightly above the recommended range of 6 to 8 and only at the March sample date. Conductivity
was highest for the June readings and lowest for the March sampling. This is probably linked to
the amount of runoff in June compared to March. Chlorophyll values were highest in Mar, but all
values fell within the mean +/- 2SD range and were less than 20 gg/1 which is often set as a
eutrophication criteria level. Nitrates and Total P values were also low. No pesticides were
detected in any sample.
Groundwater monitoring data found low levels for TDS for all sample dates with the highest
values found in October and November. pH was within an acceptable range for all dates with
only the MW6 location above 8 and only for the Mar and Jun dates. Conductivity was lowest at
the June sampling and highest at the October date. Conductivity values were lower in November
than October for all locations except MW6 although this value was still within acceptable limits.
Nitrate values were very low with no concentration above 0.25 mg/1. Total P was highly variable
not only among sample locations but among sample dates at the same location. The MW2
November sampling date value was the only one outside the acceptable limit and only by 0.8%.
No pesticides were detected in any sample.

Benthic Macroin vertebrate Data
Benthic macroinvertebrates were collected from four streams within the boundary of the Project
on March 25, 2003. Samples were collected using the Ephemeroptera, Plecoptera, and
Trichoptera (EPT) method described in the most recent Standard Operating Procedures from
DWQ. It involves one kick net sample, one sweep net sample, one leaf-pack, and one visual
collection at each location. The final bioclassification for this type of collection is based solely
on the number of EPT taxa in the sample.
The bioclassifications for the streams sampled on March 25, 2003 were "Poor" for all sample
locations with EPT numbers of Creek 1 (4 EPT taxa present), Creek 2 (6 EPT), Creek 3 (2 EPT)
and Creek 4 (6 EPT).However, the streams sampled were so small that state biologists would not
apply a bioclassification to them. DWQ is currently developing criteria to help assess small, first-
order streams such as the ones sampled for the Project (communication between Aqua Tech
personnel and Patricia MacPherson, NCDENR). Moreover, the extreme drought during 2002 is
likely to have had a significant impact on these small streams from a biological perspective. Data
for 2004 will hopefully see a recovery, although only one stream at one sampling date ever had
EPT taxa which categorized it as "Good-Fair."
Macroinvertebrates collected from streams within the Project on March 25, 2003 are identified
below. An "R" means a taxon was rare (1 or 2 collected), C is common (3 to 9), and A is
abundant (10 or more).

Phase I of the environmental monitoring plan called for pre-development sampling and
analysis to establish baseline conditions at the Project. Unfortunately, drought conditions in
2001 and 2002 prevented much of the sampling envisioned by the plan. All available Phase I
data is presented in this Appendix.
Surface water quality data from the Fall of 2000 and the Spring of 2001 are presented in
Tables A-1 and A-2, respectively. During the Fall of 2000, dissolved oxygen content exceeded
what is considered a minimum threshold level of 4.5 mg/1 for all locations. Turbidity levels were
low and ranged from 2.7 to 9.4 NTU. Temperatures were moderate and averaged -21 C. Water
pH was slightly acidic to near neutral and ranged from 6.4 to 7.4 which is considered within an
acceptable range of 6 to 8. Conductivity was also low and ranged from 100 to 188 gmhos/cm.
All values fell within statistical standards of mean +/- 2 standard deviations (SD).
In the Spring 2001, dissolved oxygen content was also acceptable ranging from 6.7 to
8.5. Turbidity values varied widely from 12.5 to 410 at sample location SW 1 and 825 at sample
location SW4. All values were within acceptable statistical standards based on the mean +/- 2SD
criteria. Winter rainfall runoff and construction activities may have contributed to the increases
observed for the two sample locations compared to Fall 2000 values. TDS values were also
variable, ranging from 94 to 302. However, values for all locations were within acceptable limits.
Temperature was consistent across all sample locations and pH was within the acceptable range.
Conductivity was still low even with increased turbidity levels at locations SW1 and SW4.
Nitrates and Total Nitrogen (N) were low with nitrates less than 0.07 mg/l for all locations. Total
Phosphorus (P) values ranged from 0.09 to 0.94 with the highest values at locations SW1 (0.54
mg/1) and SW4 (0.94 mg/1) which correlates to those locations showing increased turbidity
levels. No pesticides were detected in any of the samples.
Groundwater monitoring data for the Fall of 2001 and the Fall of 2002 are presented in
Tables A-3 and A-4, respectively. TDS values ranged from 190 to 560 mg/l. This is not unusual
since materials dissolved in groundwater will vary from one location to another. All values fell
within the mean +/- 2SD criteria. pH was also highly variable with values ranging from 5.8 to 8.3
There was no correlation with pH and TDS. Conductivity was low with values ranging from 90
to 337 kcmhos/cm. Nitrates were low at all locations with the highest value at MW9 (1.25 mg/1).
Total N was also low with the highest value at MW2 (2.8 mg/1). Similarly Total P was less than
1 mg/1 except for MW6. No pesticides were found in any samples.
In the Fall of 2002, fecal coliform counts in groundwater varied widely from <2 to 600.
While all values fell within the mean +/- 2SD range, the values for MW 2 of 240 and MW4 of

600 would seem to be extremely high for groundwater samples. Suspended solids were low
ranging from 31 to 165 mg/1. pH was highly variable ranging from 6.0 to 9.4, however, all
values fell within an acceptable range. Conductivity was low ranging from 23 to 65. Nitrate
levels were acceptable ranging from 0.05 to 2.7 mg/1. Total P ranged from 0.06 to 1.41 mg/l.
There was no correlation between Total P levels from the previous sample date. The location
with the highest value for Total P at the Fall 2001 sample date (MW6) with a concentration of 5
mg/l had an extremely low value of 0.12 mg/l at this sampling. Only the value from MW2 had a
value outside the acceptable range of mean +/- 2SD and it was only 1.4% greater. No pesticides
were detected in any samples.
Benthic Macroin vertebrate Data
Benthic macro invertebrates were collected from three streams within the boundary of the
Project on October 12, 2000. A fourth stream was scheduled to be sampled, but it had obviously
been dry for some time prior to the sampling date. Samples were collected using the EPT
method. The final bioclassification for this type of collection is based solely on the number of
EPT taxa in the sample.
The bioclassifications for the streams sampled on October 12, 2000 were "Fair" for Creeks 1 and
4 where there were 8 and 9 EPT taxa, respectively, and "Poor" for Creek 2 where only 2 EPT's
were present. The streams sampled were so small that state biologists would not apply a
bioclassification to them.

Benthic macroinvertebrates were collected from three streams within the boundary of the Project
on March 15, 2001. A fourth stream location was scheduled, but it was dry in spite of recent rain.
Samples were collected using the EPT method.
The bioclassifications for the streams sampled on March 15, 2001 were "Good-Fair" for Creek 1
(19 EPT taxa present), "Poor" for Creek 2 (4 EPT) and "Fair" for Creek 4 (12 EPT). As
previously noted, the streams sampled were so small. that state biologists would not apply a
bioclassification to them.
