StolIDwater dischruge associated with small consh'llction activity means the discharge of stmDlwater from consh'llction activities that result in land disturbance of equal to or greater
than one acre and less thau five acres. Small constmction activity also includes the disnnbance of less than one acre of total land area that is part of a larger common plan of development
or sale, if the larger common plan will ultimately disturb equal to 0" greater than one and less than five acres. d) Qualifying Local Program: This pennil includes conditions that incorporate
qualifying local erosion and sediment conh'lll program (Qualifying Local Program) requirements by reference. A Qualifying Local Program is a municipal stOlIDwater program for stOlmwater
discharges associated with small construction activity that has been formally approved by the Division. Other Definitions: Defmitions of additional telms can be found in Part I.E. of
this penni!. 3. Permit Coyerage Without Application for small construction activities under a QuaIlfylng Local Program l!!J!y If a small construction site is within the judsdiction of

time and date of the change(s) in the field, an identification of the BMP(s) removed or added, and the location(s) ofthose BMP(s). 6. Inspections Site inspections must be conducted in
accordance with the following requirements and minimum schedules. The required minimum inspection schedules do not reduce or eliminate the pennittee' s responsibility to implement and
maintain BMPs in good and effective operational condition, and in accordance with the SWMP, which could require more frequent inspections. a) Minimum Inspection Schedule: The petmittee
shall, at a minimum, make a thorough inspection, in accordance with the requirements inI.D.6.b below, at least once every 14 calendar days. Also, post·st01m event inspections must be
conducted within 24 hoUl's after the end of any precipitation or snowmelt event that causes surface erosion. Provided the timing is appropriate, the posHt01m inspections may be used
to fulfill the 14-day routine inspection requirement. A more frequent inspection scliedule than the minimum inspections described may be necessaty, to en8llre that BMPs continue to operate
as needed to comply with the permit. The following conditional modifications to this Minimum Inspection Schedule are allowed: 1) Post·Storm Event Inspections at Temporarily Idle Site,:'
If no construction activities will occur following a stOlm event, post .. storm event inspections shall be conducted prior to re-conunencing constlUction -activities, but no later than
72 hours following the stonn event. The OCCUlTence of any such delayed inspection must be documented in the inspection record. Routine inspections still must be conducted at least evel)'
14 calendar days. 2) Inspections at Completed SltesfAreas -For sites 01' portions of sites that meet the following criteria, but fmal stabilization has not been achieved due to a vegetative
cover that has not become established, the pennittee shall make a thorough inspection of their stonnwater maoagement system at least once evely month, and post· . stOlID event inspections
are not required. This reduced inspection schedule is only allowed if: i) all construction activities Utat will result in surface ground disturbance are completed; ii) allaetivities
required for fmal stabilization, in accordance with the SWMP, have been completed, with the exception of the application of seed that has not occuned due to seasonal conditions or the
necessity for additional seed application to augment previous efforts; and iii) the SWMP has been amended to indicate those areas that will be inspected in accordance with the reduced
schedule allowed for in this patllgraph.
PARTI Pelmlt -Page 13 Pennit No. COR-030000 D. TERMS AND CONDITIONS (cont.) 3) Winter Conditions Inspections ExclusIon -Inspections are not required at sites where construction activities
are temporarily halted, snow cover exists over the entire site for an extended period, Jllll! melting conditions posing a risk of surface erosion do not exist. This exception is applicable
only during tbe period where melting conditions do not exist, and applies to the routine 14-day and monthly inspections, as well as the post-stormevent inspections. The following information
must be documented in the inspection record for use of this excluslon: dates when snow cover occurred, date when construction activities ceased, and date melting conditions began. Inspections,
as described above, are required at all other times. When site conditions make th. schedule required in this section impractical, tbe permittee may petition the Division to grant an
alternate inspection schedule. b) Inspection Requirements 1) InspectIon Scope -The conslluction site perimeter, all disturbed areas, material andlor waste storage areas that are exposed
to precipitation, discharge locations, and locations where vehicles access the site shall be inspected for evidence of, or the potential for, pollutants leaving the construction site
boundaries, entering the storrowater drainage system, or discbarging to state waters. All emsion and sediment control pl .. ctices identified in the SWMP shall be evaluated to ensure
that they are maintained and operating correctly. 2) Inspection ReportIRecords -The permittee shall keep a record of Inspections. Inspection reports must identify any incidents of non-compliance
with the terms and conditions of this permit. Inspection records must be retained for three years from expiration or inactivation of permit covemge. At a minimum, the inspection repOlt
must include: i) The inspection date; ii) Name(s) and title(s) of pel~onnel making the inspection; iii) Location(s) of discharges of sediment or other pollutants flum the site; iv) Location(s)

iii, iv, v, and vi, above, dates corrective action(s) taken, and measmes taken to prevent future violations, including requisite changes to the SWMP, as necessary; and viii) After adequate
con-ective action(s) has been taken, or where a report does not identify any incidents requiring con-ective action, the l'eport shall contain a signed statement indicating the site is
in compliance with the permit to the best of the signer's knowledge and belief. c) Required Actions Following Site Illspectlons -Where site inspections note the need for BMP maintenance
activities, BMPs must be maintained in accordance with the SWMP and Part I.D.7 of the pelmit. Repair, replacement, or installation of new BMPs determined necessary during site inspections
to address ineffective or inadequate BMPs must be conducted in accordance with Part I.D.8 of the permit. SWMP updates required as a result of deficiencies in the SWMP noted during site
inspections shall be made in accordance with Palt I.D.S.c ofthe pelmit. 7. BMP Moiutemtnce All erosion and sediment control practices and other protective measures identified in the
SWMP must be maintained in effective operating condition. Pl'Oper selection and installation of BMPs and implementation of comprehensive Inspection and Maintenance procedures, in accordance
with the SWMP, should be adequate to meet this condition. BMPs that are not adequately maintained in accordance with good engineering, hydrologic and pollution control practices, including
removal of collected sediment outside the acceptable tolemnces oflbe BMPs, are considered to be no longer operating effectively and must be addressed in accordance with Part I.D.S, below.
A specific timeline for implementing maintenance procedUl'es is not included in this permit because BMP maintenance is expected to be proactive, not responsive. ObselVations resulting
in BMP maintenance activities can be made during a site inspection, or dUling general obselVations of site conditions.
PART! Pennit -Page 14 Pennit No. COR-030000 D. TERMS AND CONDITIONS (cont.) 8. Replacement and Faned BMPs Adequate site assessment must be perfonned as part of comprehensive Inspection
and Maintenance procedures, to assess the adequacy of BMP, at the site, and the necessity of changes to those BMPs to ensure continued effective perfonnance. Where site assessment results
in the detennination that new or replacement BMPs are necessary, the BMPs must be installed to ensure on-going implementation ofBMPs as per Patt I.D.2. Where BMPs have failed, resulting
in noncompliance with Palt l.D.2, they must be addressed as soon as possible, immediately in most cases, to minimize the discharge of pollutants. When new BMPs are installed or BMPs
are replaced, the SWMP must be updated in accordance with Part I.D.5(c). 9. ReportIng No scheduled reporting requirements are included in this pennit; however, the DIvision reserves
the right to request that a copy of the inspection reports be submitted. 10. SWMP AvanablUty A copy of the SWMP shall be provided upon request to the Division, EPA, or any localag_ncy
in charge of approving sediment and erosion plans, grading plans or stonnwater management plans, and within the time frame specified in the request. If the SWMP is required to be submitted

SWMPs required under this permit are considered reports that shall be available to the public under Section 308(b) of the CWA and Section 61.5(4) of the Colorado DischargePennit System
Regulations. The pennittee shall make plans available to members of the public upon request. Howevet·, the permittee may claim any portion of a SWMP as confidential in accOl"dance with
40 CPR Part 2. 11. TotAl Ma:dmum Dally Load CfMDL) If a TMDL has been approved fot· any waterbody into which the pelroittee discharges, and stormwater discharges associated with construction
activity have been assigned a pollutan!-specific Wasteload Allocation (WLA) under the TMDL, the Division will either: a) Ensure that the WLA is being implemented properly through alternative
local requirements, such as by a municipal stonnwatel' pelmit; or b) Notify the penniltee of the WI.A, and amend the permittee's certification to add specific BMPs andlor other requirements,
as approptiate. The pennittee may be required to do the following: I) Under the pennittee's SWMP, implement specific management practices based on requirements of the WLA, and evaluate
whether the requit·emento are being met through implementation of existing stormwater BMPs or ifitdditional BMPs are necessmy. Document the calculations or other evidence that show that
the requirements at·e expected to be met; and 2) If the evaluation shows that additional or modified BMPs are necessary, describe the type and schedule for the BMP additions/revisions.
Discharge monitoring may also be required. The permittee may maintain coverage under the general permit provided they comply with the applicable requirements outlined above. The Division

pennit application, including the legal contact, the project legal description or map Oliginally submitted with the application, or the planned total disturbed acreage. The pennittee
shall furnish the Division with any plans and specifications which the Division deems reasonably necessary to evaluate the effect on the discharge and receiving stream. If applicable,
this notification may be accomplished through submittal of an application for a CDPS process water permit authOlizing the discharge. The SWMP shall be updated and implemented prior to
the changes (see Part I.D.5.c). Any discharge to the waters of the State from a point source other than specifically authorized by this pelmit or a different CDPS permit is prohibited.
2. Special Notifications -DefinItions a) SpUl: An unintentional release of solid 01' liquid matedal which may cause pollution of state waters. b) Upset: An exceptional incident in which
there is unintentional and tempomry noncompliance with permit discharge limitations because offaetors beyond the reasonable control of the permittee. An upset does not include noncompliance
to the extent caused by operational elTor, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless 01' improper operation.
3. Noncompliance Notification a) The permittee shan repOlt the foHowing instances of noncompliance: 1) Any noncompliance which may endanger health or the environment; 2) Any spilt or
discharge of hazardous substances or oil which may cause pollution of the waters of the state. 3) Any discharge of storm water whioh may cause an exceedance of a water quality standard.
b) For all instances of noncompliance based on environmental bazards and chemical spills and releases, all needed information must be provided orally to the Colorado Department of Public
Health and Environment spill repOlting line (24-hour number for environmental hazards and chemical spills and releases: 1-877-518-5608) within 24 hours from the time the permittee becomes
aware of the circumstances. For aU other instances of noncompliance as defined in this section, alt needed infOlmation must be provided orally to the Water Quality Control Division within
24 hours from the time the permittee becomes aware of the circumstances. For all instances of noncompliance identified here, a written submission shall also bepmvided within 5 calendar
days of the time tltepem,;ttee becomes aware of the circumstances. The Wlitten submission shalt contain a description of: I) The noncompliance and its cause; 2) The period of noncompliance,
including exact dates and times, and ifthe noncompliance has not been corrected, the anticipated time it is expected to continue; 3) Steps taken or planned to reduce, eliminate, and

a regulalolY change. The federal Energy Policy Act of 200S exempts nearly a/l oil and gas cOllslmction activities from federal requiremenls lInder the Clean Water Act's NPDES sto17l1water
discharge penni! program. In Janumy 2006, Ihe Colorado Waler Quality Conlrol Commission held a hearing to delemline what eflects, if any, the change in foderallaw would have upon Colomdo's
stormwater regulations. The Commission delermined that oil and gas cOllstruction sites in Colorado that disturb one or more acres are still required to be covered under Colorado's stormwater
peJ711itting regulatiolls (Colorado Discharge Permit System (CDPS) regulations (SCCR 1002-61)). In practice, oil and gas construetioll sites have the same requiremellls under this permit
as do other types of conslruction. Howevel; this permit cOlI/alns some referellces 10 Ihe federal Clean Waler Act; gellerally these references are 1101 applicable to oil and gas eonsh'uetion

PART II Petmit -Page 25 Petmit No. COR·030000 II. CHANGES IN THIS GENERAL PERMIT (cant.) 1. Stormwater Management Plan (SWMP) -COlltellts The SWMP Contents section has been modified.
Some of the changes are limited to organization of illjormatioll, which does 1I0t require modification of an exisling permittee's cu,.rent SWMP. Most of the SWMP changes involve either
clarifications, reformatting. or taking recommendations fi'om the Division's SWMP gUide and making them permit requiremellts (e.g .• vehicle tracking COlltrols, BMP illstallatioll specifications).
If an existing permittee (Le., those with pel"lnit covel"Qge before JI/ne 30, 2007) followed the recommendations ill the SWMP guide (Appendix A of the permit application), tlten their
SWMP will presumably meet tlte new requirements. Howevel; for any existing permittees who did not follow tlte applicable SWMP gllide recommendations, their SMWP IIIl1st be amended to
inelllde the new required items: -SWMP Administrator -Identification of potential pollutalll sources -Best Management Practices descriptions and installation specificatiolls, ine/uding
dedicated COllcrete or asphalt batclt plants; vehicle tracking control; and waste mallagement and disposal (inciuding concrete washout activities). For existing permittees, any SWMP
changes based on the change ill permit requirements lIlust be completed by October 1, 2007. The plall is not to be submitted to the Divisioll unless requested, but must be available

plan requiremellls, and implemelltatioll. 1. Site Descriptio1/: The requirement to provide an estimate of tlte run-off coejJic/el/l has been removed. The run-off coeffiCient as currently
utilized ill the SWMP may not collfribllte sufficiently to penn it compliance tojustifY the eff0l1 ill determinillg accurate.values. SeePal·t I.C.} of the permit. Howevel; tlze Division
still encourages use of the coefficient as needed to adequately evaluate site-specific BMP selection alld design criteria (e.g., pond capacities, BMP location, etc.) See Section C.2
of the SWMP gllidance (Appmdix A of the penni! application). 2. Site Map: Tlte requirement to identifY bOlll/daries of the IOO-yearjlood plain has been removed. The boundaries as currently
utilized ill the SWMP may I/Ot contribute slifficientiy to permit compliance to justifY the effort in determilling their location. See Part I.e.2 of the permit. 3. Stonlllvaler Mallugemelll
CO//trols: This sectioll has beell modified to require identification of a SWMP Administrator alld all potential pollutallts sources ill the SWMP. See Pal"! I.C.3 afthe permit. a) The
SWMP Administrator is a specific iltdivldual(s), position O/'title who is responsiblefor the process of developing, implementing, maimaining, and revising the SWMP. This individual serves
as the comprehellsive poillt of colt/act fa}' all aspects of the facility's SWMP. Tllis requiremellt may lIecessitate challges to existing permittees' SWMPs.

Prevention: This section was modified to require the following items to be addressed in the SWMP. These "equ/relllellts may necessitate changes to existillg permittees' SWMPs, This section
also requires that the SWMP provide Installation and implementation specifications for each BMP identified in the SWMP. For structural BMPs, in most cases, this must include a technical
drawing to provide adequate installation specifications. See Part 1. C. 3(c}. i) Dedicated COl/crete 01' asphalt batch plants. This sectiollrequires that the practices IIsed to reduce
the pollutants ill storm water discharges associated with dedicated concrete or asphalt batch plants be idemified in the SWMP. (Coverage ullder the cOllstructioll site SWMP and permit
is not requiredfor batch plants if they have alternate CDPS pemlit coverage.) Ii) Vehicle tracking cOlltrol. This section requires that practices be implemented to cOlltrol sediment
from vehicle tracking, alld that all such practices implemented at the site be clearly described in the SWMP. Iii) ·WastemallagementanddisposaI.This sectiol/requires that the practices
implemented at the site to control stormwaterpollutiollfrom construction site waste, inciudillg concrete washout activities, be clearly described in the SWMP. It also requires that cOllcrete
washout activities be conducted ill a manner that does not contribute pol/utants to stllface waters 01' stOl'lI/water runoff. ivY Concrete WashOtlt Water. Part I.D.3(c) of the permit
has been revised to conditionally authorize discharges to the ground of cOllcrete wash waterji-om washing of tools and concrete mi.ter chutes when appropriate BMPs are implemented. The
permit prohibits the discharge of concrete washout water to swface waters alld to storm sewer systems. Part I.C.3(c)(7) of the penllit requires that BMFs be in place to prevellt sUiface
discharges of concrete wruhout waterji'om the site. The use of tlllibled pits to colllain concrete was/lOut water is a COli/ilion practice ill Colorado. The DiyisiOIl has further evaluated
the lIeedfor a permit for discharge of concrete washout water to the gJ·Otllld. The Division has determilled that the use of appropriate BMPs for Oil-site washillg of tools alld cOllcrete
mixer chutes would prevent any significalll discharge to gJ·oUlldwater. BMPs to protect groundwater are required by Part I.C.3(c)(7} of the pennit. Because pH is a pollutant of cOllcel1lforwashout
activities, the soi/must have adequatebujJel7ng capacity to result inprotectioll of the groundwater standard, 01' a liner/containment must be used. The fol/owing management practices
are recommended to prevellt all impact from unlined pits to gJ'oundwater: (1) the use of the washout site should be temporOlY (less than I year), alld (2) the washout site should be
1I0t be located in all m'ea where shallrnv gJ'oulldwater may be presellt, sllch as Ileal' lIalural drainages, springs, or wetlands.
PART II Pelmi! -Page 27 Penni! No. COR·030000 II. CHANGES IN THIS GENERAL PERMIT (contJ Where adequate management practices are notfol/owed to protect groundwater quality, tlze Department

The permit does not authorize the discharge of groundwaterji'om construclioll dewatBl7ng to swface waters or to storm sewer systems. Pm11.C.3(c)(8) of the permit requires that BMPs be
in place 10 prevenl sUlface discharges. The permittee may apply for coverage under a separate CDPS discharge permit, such as the COllstruction Dewatering general permit, if there is
a potentialfor discharges to sll/face waters. The Division has determined tltat potential pollutant sources introduced illlo gl'Oundwater !i'01ll construction dewatering opemtions do
1I0t have a reasonable potelltial to result ill exceedance of groundwater standards when the discharge is to tlte ground. The prilltmy pollutant of cOllcem in uncontaminated gl'OulldlVater
is .sediment. Although technologybased stmtdards for sediment do exist in 5 CCR 1002·41, the discharge of sediment 10 the ground as part of coltstruetiolt dewatering does not have tlte
reasonable pOlential to result in trails port of sediment to the groundwater table so as to result In all exceedance of those . standards. For a discharge of water contaminated with
other pol/utants that are prrueltt in concelltratiolts that may cause an exceedance of grotmdwater standards, separate CDPS discharge permit coverage is reqUired. Contaminated groultdwater

and thell automatically expire (all inactivationreqllest did 110t need to be submitted). The Issuance of these certifications has led to significalll confusion and incidents of noncompliance
I:esultlngfi'om permittees unintelltionally letting theil' certifications expire prior to final stabilization, as well as issues regarding billing. Therefore, the provisions for ./lOrI-teml
cel1ijlcatlons have been deleted. T. Bvpass The Division has revised the Bypass conditions in ParIII.A.5 of the permit to be consistent with the requirements of Reg lila lion 6/.8(3)(1).
The revised language addresses IInder what rare occurrences BMPs may be bypassed at a site.
PART II Penni! -Page 30 Penni! No. COR-030000 III. BACKGROUND As required wider the Cleall Water Act amelldments of 1987, the Environmental Protectioll Agency (EPA) has established aframeworkfor
regulating III/micipal and Illdustrial stormwater discharges. Thisframework Is ullder the Natiollal Pol/utant Discharge Elimillat/on System (NPDES) program (Note: Tlte Colorado program
is referred to as the Colorado Discharge Permit System, or CDP8, instead ofNPDES.) Tlte Water Quality COl/trol DIvisiol1 (lftlte Divisioll" has stormwater regulatiolls (5CCR 1002-61)
in place. These regulations require specific types of industrial facilities tltat discharge storl1lwater associated with industrial activity (illdustrial ston/lwater), to obtain a CDPS
permitfor s/lch discharge. The regulatiolls specifically illclude cOllslruction act/vities thaI disturb olle acre of land or more as industrialfacilities. Constructioll activities that
are part of a larger COlllmOIl plan of developmellt which disturb aile acre or lItore over a period of time are also illcluded. A. General Permits The Division has detenllined that Ihe
use of general pe17llits is the appropriate procedure for halldling most of the thaI/SOlids ofilldllstrial storlllwater applications withillthe State. B. Permit Requiremenls This permit
does not impose "'"/lelic ejjluellt limits or require sublllission of ejjluellt moniloring data ill the permit applicatioll or ill the permit itself The permit illstead imposes practice-based
ejjluent limitatiolls for stOl7lllvater discharges through the reqllirement 10 develop and illlplelllent a Stormwater Management Plon (SWMP). The narrative perlllit requirements inelude
prohibitions against discharges ofnon-storlllwater (e.g., process water). See Part I.D.3 of the permit. The permit condit/ons for the SWMP inc/ude the requirement for dischargers to
select, implemellt al/d mail/taill Best Mallagement Practices (BMPs) at a pe/1llitted cOlIStruction site that adequately mil/lmize pollutants itl the discharges to assure compUG/tce
wilh the terms and conditions of the pe/mit. Part I.D.2 of the permit illeludes basic design stalldards for BMPs implemellted at the site. Facilities IIII1St select, install, implement,
and maintain appropriate BMPs,followillg good engineering, hydrologic and pol/ution cOl/frol practices. BMPs implemented at the site must be adequately designed to cOl/trol all potential
pollutant sources associated wilh construction activity to prevelll pollution or degradation of State waters. Pol/ution is defined III CDPS regulations (5CCR 1002-61) as man-made or
mall-induced, or natural alteratioll of the physical, chemical, biological, and radiological ill/egrltyofwater. Utilizillg illduslly-accepted stalldards for BMP selection that are appropriate
for the conditions al/d pol/lltant sources presellt will typically be adequate to meet these criteria, since constmction BMPs are intended to pl·event the discharge of all but lIIillilllal
alllollnts of sediment or other polllltants that would not result in actual pollution of State waters, as defined above. However, site-specific design, including ongoillg assesslllelll
of BMPs and pol/utant sources, is necessary 10 ensure that BMPs operate as intellded. The permit further requires that stOl1lllvater discharges from construction activities shall not
cause, have the reasonable potelltial to cause, or measurably cOlltribute to an excursion above allY water quality standard, including nan·ative standardsfor water quality. This conditioll
is the basis for all CDPSDischarge penllits, alld addresses the need to eIlSIl/·e that waters of the State lIIailllaill adequate water qllality, in accordance with water quality stalldards,
to cOlltinlle to meet their designated I/ses. It is believed that, til most cases, BMPs call be adequate to meet applicable water quality standards. lfwater quality impacts are lIoted,
or the Division otherwise deterlllilles that additional permit requiremellfs are necessmy, they are typically imposed as follows: 1) at the renelVal of this gelleral pel1/1it 01' through
a general permit specific to all industrial sec/or (if the issue is sector-based); 2) through dil'ectiollji·om the Division based all the implemellfatioll of a TMDL (if the issue is
watershed-based); or 3) if tlte issue is site-specific, through a revision to the certijicationji·olll the Divisioll based all an inspection or SWMP review, or through all illdividual

A QualifYing Local Program is a municipal storm water program for stonnwater discharges associated with slllall construction activity that has been formally approved by the Division.
Tlte requirements for QualifYing Local Programs are outlined ill Part 61.8(12) of the Colorado Discharger Permit System Regulations (also see the Division's "QualifYing Local Programs

VIll. TERMS AND CONDITIONS OF PERMIT (cont.) MasterSWMP PART II Pennit • Page 35 Permit No. COR·030000 Often, a large constructwn project will involve mUltiple smaller cOllstruction
sites that are within a common plall of development, or multiple well pads under construction within all oil and gas weI/field. Pollutam sources and the types of BMPs used can be relatively
consistelll in such cases. A permittee could significantly streamline tlze SWMP development process through the lise of a master SWMP. SWMP ilifol71zationmust be developed and maillfainedfor
all cOllstN/ction activities that exceed one acre (01' are parI of a common plan of development exceeding one acre) conducted within the penllilted area. By developing a single masler
plan, the penni/tee can eliminate the need to develop repetitive infonl/ation In separate plans. Such a plan could inelude two sections, one containing a reference section with iliformation
applicable to all sites (e.g., illStallation details and maintenance requirements for many standard BMPs, such as silt fence and erosion blankets), and the second containing all of the
iliformation specific to each site (e.g., site EMP map, drailzage plans, details for EMPs requiring site specific design, such as retention ponds). As new activities begill, iliforlllallon
required ill the SWMP is added to the plan, and as areas become finally stabilized. the related illformation is removed. Records ofiliforlllatiollrelated to areas that have beellfillally
stabilized that are removed fi'om the active plallmust be mailltailledfor a period of at least three years from the date that the associated site is filzally stabilized. . C. Total Maximum
Dailv Load (IMDLJ If the desigllated /lse of a stream or water body has been impaired by the presellce of a pollutant(a), development of a Total Maximum Daily Load (l'MDL) may be required.
A TMDL is an estimate of allowable loadlllg ill the waterbody for the pol/utallt in questioll. Types of discharges that are or have the potential to be a sigllificant sotlrce of the
pol/utant are also identified. Ifa TMDL has beell approved for ally waterbody illto which the permittee discharges, alld storl1lwater discharges associated with cons/ruction activity
have beell assigned a pollutmlt-specific Wasteload Allocation (WLA) under the TMDL, the DMsion will either: 1. NotifY the pennittee of the TMDL, and a//lend the permittee's certification
to add specific EMPs andlor other requiremellts, as appropriate; or· . 2. ElISure that the TMDL Is being implemellled pl'Operly through altemative locairequirements, such as bya mUllicipal
stonmvater permit. (The oilly cU/nllt exmnple of this is the Cherry Creek Reservoir Control Regulation (72.0), which mandates that mUlllcipalities within the basillrequire specific BMPs
for cOllstruction sites.) See Part I.D.ll of the permitforfi/rther lIiforlllatioll. D. Monitoring Sampling alld testing of stonnwaterfor specific parameters is not reqUired 01/a routine
basis under this permit. However, the Divisioll reserves the I'jglzt to require sampling alld testlllg 011 a case·by·case basis, ill the evellt that there is reason to suspect that compliance
with the SWMP is a problem, or to measure the effectivelless of the BMPs in removillg pollutants ill tlze e.lJlllelll. See Part I.D.l(e) of the permit. E. Facility Inspec/iolls COllstruction
sites typically must illspect their stormwater mallagement controls at least eVelY 14 days alld withill 24 houl's aflel' the end of allY preclpitatioll or snowmelt event that causes
