Re: Application for Improvement Permit and Authorization to Construct for 2237 Ashwood St, Maiden, NC
Health Department file number EHPR-03-2023-43902.
Dear Jose Vallandares:
The Catawba County Health Department, Environmental Health Division on 5/10/2023,evaluated the above
referenced property at the site designated on the plat/site plan that accompanied your Improvement Permit
application. According to your application the site is to serve a 3 bedroom home with a design wastewater flow of
360 gallons per day.The evaluation was done in accordance with the laws and rules governing wastewater
systems in North Carolina General Statute 130A-333 including related statutes and Title 15A,Subchapter 18A,of
the North Carolina Administrative Code, Rule.1900 and related rules.
Based on the criteria set out in Title 15A,Subchapter 18A,of the North Carolina Administrative Code, Rule.1940
through.1948,the evaluation indicated that the site is UNSUITABLE for a sanitary system of sewage treatment and
disposal. Therefore,we must deny your request for an Improvement Permit. A copy of the site evaluation is
enclosed. The site is unsuitable based on the following:
X Unsuitable soil topography and/or landscape position(Rule.1940)
Unsuitable soil characteristics(structure or clay mineralogy)(Rule.1941)
X Unsuitable soil wetness condition(Rule.1942)
X Unsuitable soil depth (Rule.1943)
Presence of restrictive horizon (Rule.1944)
X Insufficient space for septic system and repair area(Rule.1945)
Unsuitable for meeting required setbacks(Rule .1950)
Other(Rule.1946)
These severe soil or site limitations could cause premature system failure, leading to the discharge of untreated
sewage on the ground surface,into surface waters,directly to ground water or inside your structure.
The site evaluation included consideration of possible site modifications,as well as use of modified, innovative, or
alternative systems. However,the Health Department has determined that none of the above options will
overcome the severe conditions on this site. A possible option might be a system designed to dispose of sewage to
another area of suitable soil or off-site to additional property.

15A NCAC 18A.1942 SOiL WETNESS CONDITIONS
(a) Soil wetness conditions caused by seasonal high-water table,perched water table.tidal water.seasonally saturated soil or
by lateral watcr movement shall be dcterntincd by field evaluation for soil wetness colors and field observations,and maybe
assessed by well monitoring.computer modeling,or a combination of monitoring and modeling as required by this Rule.All
sites shall be evaluated by an Authorized Agent of the Department using Basic Field Evaluation Procedures pursuant to
Paragraph(b)of this Rule.
(b) Basic Field Evaluation Procedures:
(i) A soil wetness condition shall he determined by the indication of colors of chrome 2 or less(Munscll Color
Charts)at>2"-%0 of soil volume in mottles or matrix of a horizon or horizon subdivision. However,colors of
chroma 2 or less which arc relic from minerals of the parent material shall not be considered indicative of a
soil wetness condition.
(2) A Soil wetness condition shall also be determined by the periodic direct observation or indication of
saturated soils or a perched water table,or lateral water movement flowing into a bore hole,monitoring
well,or open excavation above a less permeable horizon or horizon subdivision.that may occur without
the presence olcolors of chroma 2 or less. A soil wetness condition caused by saturated soils or a perched
water table shall be confirmed to extend for at least three consecutive days.The shallowest depth to soil
wetness condition determined by Subparagraph(b)(1)or(b)(2)of this Rule shall take precedence.
(c) Site Suitability as to Soil Wetness: Initial suitability of the site as to soil wetness shall be determined based upon the
findings of the Basic Field Evaluation Procedures made pursuant to Paragraph(b)of this Rule. Sites whcrc soil wetness
conditions arc greater than 4K inches below the naturally occurring soil surface shall be considered SUITABLE with respect
to soil wetness.Sites where soil wetness conditions arc between 36 and 4K inches below the naturally occurring soil surface
shall be considered PROVISIONALLY SUITABLE with respect to soil wetness_ Sites where soil wetness conditions arc less
than 36 inches below the naturally occurring soil surface shall be considered UNSUITABLE with respect to soil wetness.
Sites where a soil wetness condition is determined based upon the obser ation or indication of lateral water movement within
48 inches of the naturally occurring soil surface shall be considered UNSUITABLE. except when such water can be
intercepted in accordance with 15A NCAC 1 KA .1956(4).
(d) Alternative Procedures for Soil Wetness Determination:The Owner or the Owner's Legal Representative(Applicant)
shall have the opportunity to submit documentation that the soil wetness condition and resultant site classification be
alternately determined and reclassified by direct monitoring. computer modeling, or a combination of monitoring and
modeling,in accordance with a Direct Monitoring Procedure.Monitoring and Modeling Procedure,or Modeling Procedure
made pursuant to Paragraphs(e).(f), or(g)of'this Rule. This determination shall take precedence over the determination
made pursuant to the Basic Field Evaluation Procedures[Paragraph(b)of this Rule].when the conditions of Paragraphs(e).
(I). or(g)of this Rule arc met_ Determination by one of these Monitoring or Modeling procedures shall also be required
when:
(I) the Owner proposes to use a wastewater system requiring a deeper depth to a soil wetness condition than
the depth determined by the Basic Field Evaluation Procedures pursuant to Paragraph(blot'this Rule:or
(2) the Owner proposes to use sites with Group Ill or iV soil within 36 inches of the surface and where
drainage modifications arc proposed to be made,including the installation of subsurface drain tile,open
drainage ditches,or surface landscape modifications,or on such sites when fill is proposed to be used in
conjunction with existing or proposed drainage modifications. Final determination of soil wetness
condition for these sites shall be made pursuant to the Modeling Procedure in Paragraph(g)of this Rule
(c) Direct Monitoring Procedure. Soil wetness conditions may he determined by direct observation of the water surface in
wells during periods of typically high water elevations utilizing the following monitoring procedures and interpretation
method.
(I) The applicant shall notify the local health department of the intent to monitor water surface elevations by
submitting a proposal that includes a site plan. well and soil profile at each monitoring location,and a
monitoring plan no later than 30 days prior to the monitoring period. An applicant other than the property
owner shall have written authorization from the owner to be the owner's legal representative.Soil wetness
and rainfall monitoring shall be conducted under the responsible charge of a third-party consultant or by
the property owner or the owner's agent. A third party consultant is qualified when licensed or registered
in accordance with G.S.89C(Engineers).G.S.89E(Geologists).G.S.89F(Soil Scientists).or G.S.90A
Article 4 (Registered Sanitarians). if required. The Owner shall submit the name(s)of'thc consultant(s)
performing any monitoring on their behalf to the local health department.
(2) Thc applicant shall submit a site plan showing proposed sites for wastewater system. shall provide the
longitude and latitude of the site.location of monitoring wells.and all drainage features that may influence
the soil wetness conditions.and specify any proposed fill and drainage modifications.
(3) Thc applicant shall submit a monitoring plan indicating the proposed number,installation depth.screening
depth.soil and well profile,materials and installation procedures for each monitoring well,and proposed
method of analysis.A minimum of three water level monitoring wells shall he installed for water surface
observation at each site. Additional wells shall be required for sites handling systems with a design flow
greater than 600 gallons per day(minimum of one additional well per 600 gallons per day increment).
(4) The local health department shall be given the opportunity to conduct a site visit and verity the
appropriateness of the proposed plan. Well locations shall include portions of the initial and replacement
drainficld sitc(s)containing the mast limiting soil'site conditions.Prior to installation of the wells the local
health department shall approve the plan. If the plan is disapproved, the local health department shall
include specific changes necessary for approval of the monitoring plan.
(5) Wells shall extend at least five feet below the natural soil surface,or existing soil surface for fill installed
prior to July I. 1977 meeting the requirements for consideration of a site with existing fill of G.S. 130A-
341 and the rules adopted pursuant thereto. However,a well or wells which extend(s)down only 40 inches
may be used if they provide a continuous record of the water table for at least half of the monitoring
period.and one or more shallower wells may be required on sites where shallow lateral water movement or
perched soil wetness conditions arc anticipated.
(6) Water surface in the monitoring wells shall be recorded at least daily from January I to April 30.taken at
the same time during the day(plus or minus three hours).A rain(precipitation)gauge is required within
one-half mile of the site. At least daily rainfall shall be recorded beginning no later than December 1
through April 30(the end of'the well monitoring period).
(7) Interpretation Method for Direct Monitoring Procedure:The following method ofdetennining depth to soil
wetness condition from water surface observations in wells shall be used when the 60-day weighted
rainfall index for the January through April monitoring period equals or exceeds the site's long-term
(historic) 60-day weighted rainfall index for January to April rainfall with a 30 percent recurrence
frequency(wetter than the 9th driest year of 30,on average). The 60day weighted rainfall index for the
monitoring period and historic rainfall record shall be computed as:
ti�Rh, = 0.5P1,~ Pi—Pr+Pst 4-0.5Pn
Where 1y'Rl,,�, = 60-day weighted rainfall index for January to April
Po = Total December rainfall
P, = Total January rainfall
Pt = Total February rainfall
P,r = Total March rainfall
P.1 = Total April rainfall
The Department shall prepare contour maps for each county where this interpretation procedure is
proposed. Contours shall be prepared following standard interpolation procedures using normalized data
collected from all National Weather Service Stations, or equivalent, from which appropriate data arc
available,at least prior to February I of the monitoring season. Data from each station shall be normalized
by fitting a 2-parameter gamma distribution to the 60-day weighted rain fall index computed for at least the
most recent three decades of historic data.in accordance with procedures outlined in Chapter 1ff of the
National Engineering Handbook.NRC'S,USDA.From this fined distribution,the 60-day weighted rainfall
index for January through April rainfall with a 30%.50%. 70%and 30%recurrence frequency shall be
computed for each Station.to provide the raw data points from which the contour maps shall be prepared.
From these maps,the site's 6(1-day weighted rainfall index for the January through April monitoring period
shall be compared to the long-term(historic)January to April 60-day weighted rainfall index at different
expected recurrence frequencies. The soil wetness condition shall be determined as the highest level that is
continuously saturated for the number of consecutive days during the January through April monitoring
period shown in the following table:
Recurrence Frequency Range Number of Consecutive Days
January to April 6(1-Day of Continuous Saturation
Weighted Rainfall Index for Soil Wetness Condition
30%to 49.9" 3 days or 72 hours
50%to 69.9% 6 days or 144 hours
70%to 79.9% 9 days or 216 hours
80%to I O0% 14 days or 336 hours
(8) If monitoring well data is collected during monitoring periods that span multiple years.thc year which
yields the highest(shallowest)soil wetness condition shall be applicable.
(I') Monitoring and Modeling Procedure: A combination of monitoring and modeling may be used to determine a soil
wetness condition utilizing the following monitoring procedures and interpretation method.
(I) The procedures described for the Direct Monitoring Procedure in Subparagraphs(c)(I).(2).(3).(4).(5).
and(6)of this Rule shall be used to monitor water surface elevation and precipitation for determining soil
wetness conditions by a combination of direct observation and modeling.except that the rainfall gauge and
each monitoring well shall use a recording device and a data file (DRAINMOD-compatible) shall be
submitted with the report to the local health department(devices shall record rainfall at least hourly and
well water level at least daily).
(2) The ground water simulation model DRAINMOD shall he used to predict daily water levels over at least a
30 year historic time period after the model is calibrated using the water surface and rainfall observations
made on-site during the monitoring period. Thc soil wetness condition shall be determined as the highest
level predicted by the model to be saturated for a I4.day continuous period between January 1 and April
30 with a recurrence frequency of'30 percent(an average of at least 9 years in 30).
(A) Weather input files,required to run the DRAIN MOD,shall be developed from hourly rainfall
gauge data taken within a half-mile of the site and from daily temperature and hourly or daily
rainfall data collected over a minimum 30-year period from the closest available National
Weather Service,or equivalent,measuring station to the site. DRAINMOD weather data files on
file with the Department shall be made available upon request to the applicant or applicant's

the applicant or applicant's consultants.
(C) inputs shall be based upon site specific soil profile descriptions Soil and site input factors shall
be adjusted during the model calibration process to achieve a best fit by least squares analysis of
the daily observations over the whole monitoring period (mean absolute deviation between
measured and predicted values no greater than eight inches).and to achieve the best possible
match between the highest water table depth during thc monitoring period (measured-vs-
predicted)that is saturated for 14 consecutive days.
(D) For sites intended to receive over 1500 gallons per day. the soil wetness determination using
DRAINMOD shall take into consideration the impact of wastewater application on the projected
water table surface.
(E) The ground water simulation analysis shall he prepared and submitted to the local health
department by individuals qualified to use DRAINMOD by training and experience and who arc
licensed or registered in North Carolina if' required in G.S. 89C (Engineers), G.S. 89E
(Geologists),and G.S.89F(Soil Scientists).The local health department or Owner may request a
technical review by the Department prior to approval of the soil wetness condition determination.
(g) Modeling Procedure: A soil wetness condition may be determined by application of DRAINMOD to predict daily water
levels over at least a 30 year historic time period after all site-specific input parameters have been obtained.as outlined in the
DRAINMOD Users Guide. This modeling procedure shall be used when a ground water lowering system is proposed for a
site with Group III or IV soils within 36 inches of the naturally occurring soil surface.This procedure shall also be used to
evaluate sites with Group 111 or iV soils within 36 inches of the naturally occurring soil surface, where the soil wetness
condition was initially determined using a procedure described in Paragraphs (c)or(11 of this Rule and where drainage
modifications arc proposed or when fill is proposed to be used in conjunction with existing or proposed drainage
modifications.Thc soil wetness condition shall be determined as the highest level predicted by the model to be saturated fora
14-day continuous period between January I and April 30 with a recurrence frequency of'30 percent(an average ofat least 9
