FLOOD PLAINS AND NATI]RAL HAZARJDS
The proposed treatment facitity is rocated higher than the identified 1O0-year floodplain' The
floodplain was defined as a part of construction of I-70. The proposed faciiities' except the discharge
point, are out of the floodway. The 10.-year flood plain has been identified as the elevation 6102 feet
and is Presented on Figure 6'
DESCRIPTION OF SELECTED ALTERNATIVE
The insta*ation of a packed-Bed F,ter (pBF) treatment system consisting of a septic tank'
recirculation tank, geotext,e packed firters, and disinfection system with surface discharge is
proposed for the Rest Area. Manufacturer and distributor information is inciuded in Appendix D' The
treatment system is to be rocated east of the rest area and north of the access road as indicated on
Figure 6.
The proPosed PBF systeminciudesastandard't\ilo-compartmentseptictankforsolids

effluent PumPing system will dose effluent to the surface of geotextile filters'The geotextile filter

nitrogen to nitrate nitrogen. The treated effluent flows back to the recirculation tank where it mixes
with the anaerobic septic tank effluent. Additional bio-chemical reactions occur which convert the
nitrate nitrogen into a harmress and odorless nitrogen gas, which is vented from the system' Total
nitrogen reductions of 40% to SOohcan be anticipated. After 3-5 passes through the geotextile filters'
.,_r^_r.ionhoroerotheproposedultra-violetlightdisinfectionsystem'once
theeffluentrsreadyfordischargetotheproposedultra-violetlightdisit
disinfected, the effluent will discharge to cororado River. The bio-chemical oxygen demand (BoDs)
and total suspended solids (Tss) concentrations should consistently be iess than 10 mg/l'
Introduced in the early-1990,s, numerous pBF systems have been instalied in the united
States. Audits and routine monitoring by county, state, and federar agencies have shown generally
excellent results, even with a wide variation in incoming flows. our office may be contacted for
literature references "
once Site Approval is obtained, a finar design win be compreted. The following is a general

INSTITUTIONAL ARRANGEMENTS
cDor must maintain and enforce a policy of adherence to the requirements in the discharge
permit issued by the cDpHE, *QCD. Since wastewater wil1be generated only by onsite facilities' a
user contract will not be necessary'
I
I
I
MANAGEMENT CAPABILITIES
The system is to be operated and maintained by a certified wastewater system operator, by
cDor persorurer, or through a contract with a wastewater system management company' An
operation and maintenance contract is to remain in effect at ail times' An alternative is for
managementresponsibilitiestobeacceptedbythepropertyowner,anddutiesperformedbya
certifiedoperatorundertheemploymentofCDoT.
cDor is to accept the financial responsibiiity for successful operation and maintenance of the
facility. operating costs of the proposed wastewater system is estimated to average $2500 per year'
Fa,ure to operate and maintain the treatment system equates to crosure of the Rest Area to prevent a

determine the assimilative capacity of the Colorado Ri'""'"*it'e Hanging Lake Rest ATeaWWTF
for pollutant, or "on..*. For all parameters except ammonia a technical analysis of stream
assimilation capacity uses the annuar ro* no., (lowesiof th"*o",rrrv low flows) as calcuiated in the
row flow analysis. Fo, *ooia, it is tt "

each month using the monthiy row ttows cui"otated in the 1ow flow analysis, as the regulations aliow
the use of seasonal f1;, when establishing assimilative capacities'
The assimilative capacity analysis consists of steady-state mass-balance calculations for most
pollutants, *a *oATri.rg i* ott., pollutants such as ammonia' A mass-balance equation is used to

6.1 .2. The length of the deadman is typically equal to the length
of the tank.
6.1.3. A deadman may be fabricated in multiple sections as long
;r il;il;l;;jtn it not decreased and each section contains at
leasttwo baianced anchor Points'
6.'1.4. The width and thickness of the deadmen depend on the
t.nf<. Oirr.t., water-table height' number of attached collar
risers and burial dePth'

Accordingtoyourresearch,you,reloadingyourtextilefiltersashighasa5gpd/ff.
Tbat,s much, much higher than th,e ,ypiroiioading rates for intermittent sanil Jilters (1'25 gpd /
ff) anit recirculating ionAfiUers (5 gpd /ft)' How can you do that?
There are a number of reasons why. The first reason is the larger surface area of the textile media'
as noted in the previous question. The rarger surface area gives greater colonies of bactena an
interface for oxYgen exchange'
The second reason is the greater void space in text*e media, which is about 3 times greater than
rhat of sand. void space does two ,*r:H;i"*r'i*'.,1r* now of oxTgen and provides a larger
void for solids u"",i-.tri*ion. Free n"* "i*rren cglbined with a large interface for oxygen
transfer optimizes ;;;;;;il digestion. n " seri (Sorids e.r"*"i"rion i-ate) is a measurement of
how iong a filter *iii;ribefo-re it "l";;';i;h "tt*i".Tg inorganic particles' as well as srease
and oil. The greate'lt'" SAR' the longer life a filter will have'
The third is the greater water holding capacity of thl textile media. An increased water holding
capacrty equates _] *or. sustainable;;;;";"nt for uurt..iu to live in. A poor water holding
capacity creates * "*iron*ent
where bacteria dry out and sloughing cT occur' Finally' water-
holding capaclry rs important, u""urrr.tiln water-ho.1di"g "upu"'ity
give-s bacteria the time to
digest organic *^rr. i*iie media rru. u[o,'t three times tr'" *uto-t'olding capacity of sand'
It,simportanttonotethatthesefactorscombinel"".}:1.:"ostantialincreasesinloadingrates.For
example, orr" "rruii"ioo,
of ISF sand media has about t*i;;; much surface area as one cubic foot
of RSF sand media. ISF sand media J* uu, a betrer **", ;;1d;; capacity, However the l0ading
rate of the RSF ,;J;;Jia is actually;;;;es higher due to the greater void space' If we
cornpare tt" ,*ar"aias, the ISF has more surface area ""i gr"^"r water holding capacity while
tne RSf has greater void sPaces'
To conclude, textile media optimizes treatment with a large srirfa "?y"?, Er,eater void space', and
increased water holding capacity,*hi;;;i;s the combinutio" of the best attributes of the ISF
and the RSF into or" **pu"t, pu"t "i f"a nr,"r. ro, *rir r^"ur*,texile tilt"]t have been found

How long will the media last?
The media should last indefinitely,nder normal domestic discharge conditions' The synthetic
