In general, complying with this prerequisite is standard practice in most urban and suburban areas, where most or all of the EPA Construction General PermitEPA's Construction General Permit. Outlines the provisions necessary to comply with Phase I and Phase II of the National Pollutant Discharge Elimination System (NPDES) program. (CGPEPA's Construction General Permit. Outlines the provisions necessary to comply with Phase I and Phase II of the National Pollutant Discharge Elimination System (NPDES) program.) requirements have been adopted and implemented at the state or county level. Regulators at those levels often threaten heavy fines for not complying with CGP requirements, so most projects do so without the added incentive of the LEED prerequisite.
Early on in project planning, compare your local code requirements to the CGP to determine which is more stringent. If your local code is more stringent, then you will meet the prerequisite just by following that. If it is less stringent, follow the CGP to achieve the prerequisite.
The CGP extends compliance with the National Pollutant Discharge Elimination System (NPDESThe National Pollutant Discharge Elimination System (NPDES) is a permit program that controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters.) stormwater regulations to construction activities. It has three main categories that need to be addressed as you create an erosion and sedimentation control (ESC) plan:
Simply put, your ESC plan implements good housekeeping on a site-wide basis, minimizing the impact of construction on local environmental resources and surrounding properties.
As written, the CGP applies to sites of one acre or larger. However, all projects pursuing LEED certification must meet the requirements of the CGP, regardless of size.
Often the civil engineer is responsible for creating the ESC plan, which is then implemented by the general contractor. Smaller projects may find the contractor is the one providing the plan, often one that is standard for their company.
The ESC plan may be submitted as documentation, in the form of a site plan or a narrative report.
Inlet protectionTo demonstrate that your ESC plan was implemented, your projects will also be required to provide one of the following:
Many urban projects have zero lot lines and, therefore, no associated “site.” If your project is like this, you are not exept from developing and implementing an ESC plan. However, strategies and BMPs will differ from those implemented on projects with site area. Inlet protection will still be required, even if storm drains are not immediately on site and within your LEED boundary. Tenting work areas and using temporary enclosures can prevent dust and airborne particulatesTotal suspended particulate matter found in the atmosphere as solid particles or liquid droplets. Chemical composition of particulates varies widely, depending on location and time of year. Sources of airborne particulates include: dust, emissions from industrial processes, combustion products from the burning of wood and coal, combustion products associated with motor vehicle or non-road engine exhausts, and reactions to gases in the atmosphere. (EPA) from leaving the project site. Vehicle tracking and concrete washout will also need to be addressed, and washout will likely have to be managed onsite somehow. Don't forget to include staging areas.
Concrete washoutDocument the plan with a narrative report explaining which CGP requirements don’t apply to your project conditions, which do, and how you plan to implement them.
No. You must always do an ESC plan according to the credit requirements. We have yet to hear of a project that didn't have some issues to address. See the above section titled "Zero lot lines."
BMPs for steep slopes should address soil retention, but not water retention. These could include silt fencing and straw wattles, hydro seeding and stabilized mulching, geotextiles and mats, and most importantly, preservation of natural vegetation.
LEED does not offer specific requirements on ESC control measures, beyond the standards that it references, and the documentation requirements. LEEDuser recommends working with a civil engineer who understands the LEED and EPA requirements, and relying on the professional judgment of the engineer for specific technical questions. LEEDuser has not heard that LEED reviewers are deeply scrutinizing ESC plans and coming back with highly technical questions.
This prerequisite offers several options for documentation, including date-stamped photographs, a narrative describing the ESC plan implementation, or a builder declaration of periodic inspection and documentation of ESC implementation. You can rely on project specifics to choose the best option for you—LEED has no preference.
Ideally, use your cameras to imprint a visible date on a corner of the image. Most cameras offer this option. Digital files also typically encode a date when the file was created, or encode that date in the file name, and while these methods aren't ideal, some project teams have reported success submitting this type of documentation.
As long as the project has been actively implementing an ESC plan during the current development of the project site, you should be okay. If that's not the case, then the outcome will depend on project specifics, and you will likely need official guidance from GBCI.
LEEDuser has advised teams that in multi-phase projects, it's okay to focus documentation of the ESC plan only on the current phase, when LEED became part of the project scope. In general, if there is some question about whether controls were in place during the LEED project, you may not be able to earn the prerequisite.
USGBC has not identified specific standards for judging this, or defined certain codes as compliant with the credit, or not. The stringency of other codes relative to EPA's Construction General Permit is judged on a case-by-case basis.
Review pages B-1 through B-4 of the EPA Construction General Permit (CGP) (see Resources) to determine if your state administers the CGP requirements for all projects.
In regions where the EPA CGP is not standard practice, compare the local code with the CGP and make adjustments, if necessary, to include all the CGP requirements.
Meeting the requirements of this prerequisite is standard practice in many regions and, therefore, no- or low-cost for LEED.
The materials cost to implement these measures is minimal and can potentially save money by preserving the vegetation and topsoil on-site.
Conduct a site evaluation to assess opportunities for minimizing the alteration of the natural stormwater runoff patterns of your site and the disruption of mature vegetation, especially trees. This will save money and time in terms of earth-moving and replanting vegetation.
Ask your civil engineer about soil types and what type of drainage you will have once the topsoil and vegetation are disturbed.
Establish who will create your ESC and stormwater pollution prevention plans. Usually, the civil engineer creates them, and the contractor is responsible for their onsite implementation.
It is best to include your ESC plan in both project drawings and project specifications so that the intention of the plan is clearly communicated to the project team, especially contractors and subcontractors.
Determine whether the 2003 EPA CGP or local erosion and sedimentation control standards are more stringent―and follow the more stringent standards. Often the state department of environmental protection or equivalent will have a written ruling on the comparison of the CGP standards and the local standards.
A good first step to determine which is more stringent is to review your local code to be sure it contains at minimum the general categories contained in the CGP. If not, you’ll know that you need to follow the CGP. If so, you’ll need to review your local code in detail to be sure that all of the requirements are included. The general categories are as follows:
If local standards are equal to or more stringent than the CGP,you'll need to provide a narrative report detailing this. Write the narrative when you do the comparison, so that it's fresh in your mind.
Create a draft ESC plan drawing or a narrative report that outlines how your project will comply with the requirements of the CGP or the local standard. See the Documentation Toolkit for samples.
Make sure that you use the same LEED project boundary as all other LEED credits your project is attempting (this is particularly relevant with other Sustainable Sites credits).
A project drawing should include anticipated stormwater flows and indicate the location and type of any planned ESC measures.
All written ESC plans must include the following:
Determine which path your project will follow to demonstrate implementation compliance: inspection report, photos, or narrative report.
Photos are likely the easiest way to demonstrate compliance, unless an inspection report has already been completed.
Develop a site-wide, earth-moving schedule to minimize the impact on established vegetation and to stockpile topsoil and protect it from erosion. This can also complement your strategy to achieve SSc5.1: Site Development—Protect or Restore Habitat, by limiting site disturbance and maintaining native vegetation.
Proper scheduling and staging of earth-moving activities can lower the costs associated with sediment and erosion controls.
Retain as much of the existing vegetation as possible, not only to lower costs for replacements, but also to decrease the cost of structural controls.
Careful implementation of the stormwater pollution prevention plan (SWPPP) by the contractor should inform the design and installation of stormwater management systems onsite. This will enable those systems to be integrated to the greatest extent possible during construction, preventing unexpected stormwater discharges into receiving waterways.
If attempting one or both of the stormwater management credits SSc6.1 and SSc6.2 confirm with the contractor that the SWPPP accurately represents the hydrologic characteristics of the site and is performing as anticipated. Check on assumed infiltration rates, suspected rate and quantity of run-off to receiving streams, and discuss potential storage options. Make changes to the stormwater management system accordingly to improve its effectiveness and ensure that the credit calculations are accurate.
Review your ESC and stormwater pollution prevention plans to ensure adequate measures will be implemented to meet the CGP, or local requirements. A discussion between the contractor and the civil engineer on the schedule and implementation of planned measures should be part of this review.
Finalize your ESC plan drawings or narrative report. Verify that your plan is in compliance with the CGP or local standards.
Review all ESC project drawings and construction specifications prior to construction activities.
Verify that all ESC measures are in place before any construction activities begin.
The general contractor implements the ESC plan until construction is completed and all disturbed areas have been stabilized.
Have a representative from the general contractor’s office onsite daily to monitor and implement necessary measures laid out in your ESC plan.
The civil engineer, contractor, or a third party should inspect your ESC plan measures on a weekly basis (bi-weekly if inspections are also conducted after any weather event involving more than 0.5 inches of rain), and submit status reports on ESC plan implementation. These reports should include labeled and dated photographs, an inspection log, or a narrative report describing the performance of the measures implemented.
Provide corrective actions immediately after any rain event.
Corrective actions can range from adjusting the placement of silt fencing and removing debris from stormwater catchment basins to replanting areas of temporary seeding and adding material to gravel skirts at entrances and exits.
Preserve existing vegetation, especially mature trees, whenever possible. This will decrease costs for temporary stabilization measures and erosion controls. In addition, the vegetation may also be used as part of your landscaping plan.
After completion of all construction activities, document credit compliance in LEED Online by uploading these documents:
Implement an ongoing stormwater system maintenance plan with the landscape manager. This should include a regular schedule for monitoring the performance of the stormwater management system and guidelines for repairing or modifying site features that are causing problems. These guidelines could include replacing or increasing vegetation, redirecting runoff, and increasing storage.

Hello again, we are working on a project for which we are installing a sediment basin. According to EPA we could use the calculation of 3600 ft3 / acre drained to size it. Most of the drainage area will remain undisturbed since it will be a preserved area. Diverting the water from undisturbed areas is quite difficult because of topographical constraints. We found in a manual that from undisturbed areas, we could use a runoff value of 500 ft3/acre drained in addition to the 3600ft3/acre drained of disturbed areas. Would doing this be compliant with EPA's regulations? We are outside the US and not very familiar with these regulations. Thanks!
All I have ever seen or used is 3600 cf/ac or 5000 cf/ac for high quality watersheds.
Compost filter socks can be installed in virtually any terrain, and used for diversion. Have you considered these?
Thanks Michael, here is where we found the reference to the 500 ft3/acre drained from undisturbed areas:
We live in a place where things as compost filter socks are not commercially found, so practically any diversion would have to be made doing earthwork, which we are trying to avoid. The site where the basin would stand is also constrained and almost not enough to divert 3600 ft3/acre from all areas. Do you think we would comply using 500cf/ac in undisturbed areas?
we are working on a project in an estate, part of this estate is the current LEED project, with its own LEED boundary. The estate has many projects going on and the construction company which works exclusively for the project owner, has its own concrete manufacturing plant within the estate, but outside de LEED boundary. The plant has a concrete washout facility that is well documented and that they use for all the projects they are working on. They fill the concrete mixer trucks with water inside the LEED boundary and do the washout when they arrive to the plant, a few miles away. Will this practice be OK with the ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation Plan requirements? A concrete washout area for small hand or electric mixers has been provided on site. Thanks
I see no problem with this. Just document it in the narrative.
Thank you Michael!
I have a question regarding the control measure for the control for all the vehicles leaving the project, the most common is cleaning all the vehicles (washing the tires) before leaving the project in order to keep the public roads clear of debris and mud.
There is a project we are working on, where the access road outside the site is unpaved, it is a 400 yards road of exposed soil and this road goes directly to the main street which is paved.
What king of strategy can be documented, if washing tires can damage the roads, because the vehicles will affect this road when leaving the project site. Should the outside road also have a control measure even if it is outside the LEED boundary? or can we comply with the pre-requisite only documenting the measures inside the boundary?
What are the common measures used for dust control? SWPP plans I see around here always deal with soil erosion, but dust control is commonly ignored by inspectors and on most construction sites. We are in an area with about 30" rainfall per year.
Lawrence, I typically use on site water trucks to wet down the disturbed areas as needed. Additionally, if wind is an issue, you should use tarps over any topsoil stockpiles.
We are trying to respond to a review comment on this project asking about dust control. About the only thing I am sure that was done, was to have a water cannon spraying down a concrete-framed structure as it was being torn down with track-hoes. Most of the site was graveled during the construction period, but there was no wetting of exposed soil or covering of piles with tarps. We do not live in an area with much in the way of wind, nor much problem with blowing dust (fighting mud is a normal and constant problem though), and I can't remember ever seeing a project around here in the Midwest in the last 30 years where any wetting of soil or covering of piles was ever done. This sounds like the kind of comment you'd get from a reviewer from dry California who'd never been to Flyover country! I am wondering if the whole prerequisite will be rejected if we can't respond to this review comment?
Could anyone kindly clarify the following issue:
I work with a project on construction of industrial plant. Prior to construction activities the topsoil was completely removed from the site leaving underlying soil layer exposed. Since this layer consists of sand only (a few tens of meters deep) and construction activities take place on 99.9% of the site area, I have at least 3 questions that I struggle to find answer to:
1. Stabilization of soil. Are there any measures that are relevant to this case?
2. Dust control. Sprinkling is adopted for the project to prevent erosion and air pollution. What more can be done?
3. Since an access to the construction site is provided by a 600m (away from paved road) stretch of gravel/dirt road, does it make any sense to minimize sediment track-out (as in art.184.108.40.206 EPA CGPEPA's Construction General Permit. Outlines the provisions necessary to comply with Phase I and Phase II of the National Pollutant Discharge Elimination System (NPDES) program.)?
Thank you very much.
1. Soils stabilization. Standard practice is to really only strip the topsoil far a few days worth of work. Typically 3. If the entire site is stripped, any areas to be open for longer than 3-4 days should be seeded and stabilized with hay at a rate of at least 1 ton per/acre, this will achieve approximately 87% less soil loss than an unprotected area. 2 tons will get you about 98.
2. On-site water is really the only thing you can do.
3. A construction entrance is typically larger d50 stone than ordinary gravel. A gravel drive is not going to be very effective.
For complicated planning reasons on a large (probably Campus) project some preliminary earthmovement and demolition will take place soon, but the project is not yet registered. An ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation plan will be included with the bid-set and will be implemented during the work, as well as any waste tracking.
Is this going to be a problem?
Amanda, this is not a problem with regards to LEED. There is no requirement to have a LEED registration in place before project work begins. I would just recommend being aware of key prerequisites and documentation needs, as you seem to be.
according to the prerequistes language the ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation plan must conform to the construction general permitEPA's Construction General Permit. Outlines the provisions necessary to comply with Phase I and Phase II of the National Pollutant Discharge Elimination System (NPDES) program. and the plan must describe the measures implemented to accomplish the following objectives:
To prevent loss of soil during construction
To prevent sedimentation of storm sewers or receiving streams.
To prevent pollution of the air with dust and particulate matter.
for international projects, do we have to comply with all requirements of the CGPEPA's Construction General Permit. Outlines the provisions necessary to comply with Phase I and Phase II of the National Pollutant Discharge Elimination System (NPDES) program. "including dewatering" or do we just write a plan describing BMPBest Management Practice for the above of measures?
Razan, note that the credit language calls for following the requirements of a CGPEPA's Construction General Permit. Outlines the provisions necessary to comply with Phase I and Phase II of the National Pollutant Discharge Elimination System (NPDES) program. or local codes, whichever is more stringent. So, if dewatering is part of the CGP but not local code, I would not advise excluding it.
Would reinjecting into a nearby water table be acceptable?
Would there be any water treatment requirments? According to CGPEPA's Construction General Permit. Outlines the provisions necessary to comply with Phase I and Phase II of the National Pollutant Discharge Elimination System (NPDES) program. treatment must accur when mixing with storm water?
My question is in regard to the following requirement from SS Prereq 1: "Create and implement an erosion and sedimentation control plan…"
In particular I am interested in USGBC's interpretation of "implement".
I live in a rural area. Erosion and sedimentation control (ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation) is required by law but local construction practices are far from ideal and inspection and enforcement is very weak.
The following occurred on two recent projects:
1. Contractor was cited for minor violations of ESC plan by local inspector. Corrective action was taken by the contractor and no pollution occurred.
2. Contractor failed to install perimeter controls (silt fence, sock, etc) in one part of the site. Uncontrolled transport of sediment off site occurred during heavy (cut less than design storm) rain events. This was never noticed, cited or corrected by the inspector. It was only brought to my attention by a local citizen after completion of the project.
I am concerned how the above events might affect LEED certification on these two projects?
Minor violations occur on every project, so I don't feel that they would weigh negatively on a project.
But if we are talking about developing an E&S plan, then flat out ignoring it, and not putting it into practice ..... it is a pre-requisite, it must be done.
Now GBCI and USGBC do not have inspectors out on the job site, so proving the plan was never implemented would be tough, IMO. You could get into this with all the credits though, energy not performing as required, water savings not up to snuff, etc.
Can we use the Infiltration Pond which is originally design for storm water collection during the operation phase of the project, can we use it as sediment trap during construction phase, noting that it is located outside the Project LEED boundary. we have a minimal average annual rainfall in dubai which is less than 100 MM.
Using permanent Stormwater facilities as sed traps is a common component of the E&S plan provided appropriate measure are taken to preserve the infiltration capacity of the sub grade soils.
Proper sequencing and construction practices should be followed to ensure that the pond will function in the permanent condition as intended.
If this is outside your LEED boundary, is this basin already serving a Stormwater function for a built condition? If that is the case, then this approach may not be acceptable, but you should verify with your local agency that has jurisdiction over Stormwater discharges.
The Pond is outside the LEED boundary but still it is within the Landlord plot limits.
The client has got a big plot and the intention is to have future extensions or phases.
Our client has purchased a graded pad site from a developer and wants to build a LEED certified project. So can we still meet the prerequisite by following the instructions for erosion control plan, etc. or are we on the hook for whatever the developer did before our client takes official possession of the site. Thank you for your help.
Michael, is there an approved E&S Plan in place for the work that has already been completed?
Not sure. I will find out what they did and reply.
See the FAQ above, "Can I still earn the prerequisite if the project started considering LEED after work began?" (You'll have to sign on as a member, which you can do with a free trial at the top of the page.)
OK, thanks. I've subscribed and read the FAQ. We have not begun work, but the speculative developer who is selling the site to my client had already graded the pad site before offering for sale. Are we responsible for his actions having chosen this site, or are we allowed to start with what we've inherited and begin E&S/documentation at this time?
Michael, did he grade the site under an approved E&S permit? Is this in the USA?
What I am getting at here, if the seller was on the up and up, and in the USA, his earthmoving activities should be covered under an existing permit (unless we are talking about a very small site?), or he ignored all the rules, in which case I'd hate to see this held against a new owner, but i'd defer to GBCI with your specifics if that is the case.
As Michael indicates, I would do some due diligence in finding out what permits and plans the seller was working under. If these are LEED-compliant, that's ideal. If not, my opinion is that it wouldn't be held against you, as a different owner commencing the LEED project.
Is maintenance plan a mandatory requirement under ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation and what should be its content?
Kindly share if any sample is available. Thanks in advance.
Define "maintenance plan" please.
Maintenance of the E&S BMPs? Such as clean sediment from sed traps when you reach the cleanout mark, replace failed silt fencing, maintain tree protection zones, wash roadways of any transported sediment, etc ?
Yes, these are common features of an E&S Plan, and should be included in your calculations, sequencing, and narrative.
Construction phase of an office building is consisting of multi stages. Those stages are including but not limited to; excavation stage, concrete skeleton stage, block work and plastering stage, curtain wall stage, MEP construction stage, interior finishing stage, exterior finishing stage, landscaping and landscaping stage and so on. Now, I bought a new building that its skeleton ONLY had been finished and still the rest of construction stages not developed until now. I am planning to develop that building to be a green building through applying green activities in construction and design phases. I want also to register the building under LEED for Core& Shell rating system v2009.
My question is regarding SSp1: Construction Activity Pollution Prevention. Can I achieve this prerequisite by implementing an ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation plan starting from this stage until the end of construction phase? The current building situation as mentioned is simply a concrete skeleton consisted of two basements, ground and six typical floors.
How is it possible to document compliance with an ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation plan in the above case given that the intent of this prerequisite is to avoid soil loss from the project site, which could be already done anyways?
Moreover, in such a case where a project has been registered beyond the excavation stage and well into the concrete stage, what would the ESC plan include then and what is the documentation required for compliance?
we have got a project in Dubai, the site witnesses very nominal rainfall in a year (average < 100 mm per year). since the storm water is not a major concern of CAPPP, and the primary objective is to control dust generated during construction activities, is it enough to erect Fencing and hoarding all around the site boundary which will mitigate dust generation, in addition to do the watering to main access roads within the site on daily basis.
Samer, please see the FAQ posted above here on LEEDuser, "I have a technical question about a specific control measure and whether LEED requires it. What guidance is available?"
I am not sure if this would fall under SSp1 or SSc4.3 but I am not seeing any provisions when it comes to the transportation of materials to a construction site. We are a Concrete Manufacturer/Supplier and we are looking into AFV for our fleet of Mixer Trucks and trying to see if there are any advantages delivering materials with a CNG Mixer Trucks when it comes to LEED projects. Any information we be greatly appreciated.
Rob, this would fall under SSp1, or possibly IEQc3.1. However, I don't think this is the kind of thing that would affect whether or not a LEED project earns this prerequisite. It's a good thing to reduce vehicle emissions, and it could be mentioned in a project's plan, but I don't think it's a difference-maker for LEED.
However, I would suggest you take a look at LEED's Clean Construction pilot credit. This might be where you could have an impact.
Thank you Tristan. I appreciate the information. I will check out the CCPC.
Please could someone advise as the best way to report the removal of a BMPBest Management Practice from the ESCP midway through the project? For example the initial site boundary has been brought in and now does not include BMP4a - Storm Water Inlets as they are now outside the site boundary. Do we need to revise and resubmit the entire ESCP, or can the client/site engineer/LEED consultant all 'sign off' BMP4a from the report - saying effectively that its ok that the BMP is 'decommissioned' from the ESCP as it is no longer required? Many Thanks in advance for any advice.
Richard, I would not overthink this. I think that having the engineer or appropriate person sign off on it with a note that it is no longer required would be fine from LEED's perspective.
I'm struggling with writing the narrative for implementation of ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation plan. My main problem is that I'm not sure what level of details are expected. I think it will be very helpful if one of you guys who has submitted this narrative before can share with me what are the main topics (headings and sub headings) that you covered in the narrative and what specific details, diagrams and/ or calculations that you provided.
I'm not even sure if we have to provide calculations in the narrative. If it is not a problem with you please share a sample narrative (my email: firstname.lastname@example.org).
Thanks a lot!
A proper Erosion and Sedimentation Control Plan protects the site from accelerated erosion, and protects the receiving watershed from pollution resulting from construction activities.
An appropriate plan should/could include design and calculations for all E&S BMPs: sed basins, traps, diversion swales, seeding, sequence of construction, etc.
This isn't something that you just "wing."
I recommend that you consult with a CE or CPESC with experience in preparing the plan and narrative.
LEED requires that you “Create and implement an erosion and sedimentation control plan…The plan must conform to the erosion and sedimentation requirements of the 2003 EPA Construction General PermitEPA's Construction General Permit. Outlines the provisions necessary to comply with Phase I and Phase II of the National Pollutant Discharge Elimination System (NPDES) program. OR local standards and codes, whichever is more stringent”.
This means that, at a minimum, you must develop a ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation, a "SWPPP", per EPA’s NPDESThe National Pollutant Discharge Elimination System (NPDES) is a permit program that controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters. General Permit. SWPPP contents are listed in Part 5. See the link below:
You must check the State requirements, since many States have been granted the authority to issue individual permits (e.g. New York’s “SPDES” General Permit – an NPDES approved state program). Depending on the jurisdiction, the SPDES could be “more stringent” and therefore, take precedence when preparing the SWPPP.
Is it acceptable to just upload a drawing with the erosion and sedimentation control measures or is it required to have an actual ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation plan as well?
In my experience they also want to see a written ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation plan that the contractor is following.
We are looking for other LEED experiences regarding an unexpected discovered archaeological finds during the excavation inside the and how we can treat this argument for SSP1.
Fabio, I would suggest that this is not an issue that LEED has any specific guidance on. LEED requires you to follow an ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation plan, which addresses erosion issues, but not cultural factors. As long as you are following laws or codes in the relevant jurisdiction, I don't think it's a factor in LEED.
I have a question regarding silt and run off. Our project is located in Phuket Thailand. Our project is planning to have a series of retention ponds and bioswales to collect rain water runoff.
The project is located on a beach on the Andaman Sea. We have a monsoon season for 6 months of the year. The storms though have occasionally hit with great intensity in the last few years. We are looking at a system design for a 10 year and 50 year storm. It is possible though the system may be overwhelmed by the rain and some silt may run into the sea. Does that disqualify us for this credit? How does the prerequisite address an occurrence such as this?
The primary component of an erosion and sediment control plan is providing a means to prevent the discharge of pollution from construction activities.
This pre-req applies to the construction phase of your project. Not the built environment. If there is a monsoon season, an appropriate E&S plan should take into account the expected stormwater runoff, and a means to capture this during the construction phase that allows the sediment to filter/settle out....you need a sediment basin or sediment trap in your design, then once your site is stabilized, they get converted to the permanant stormwater BMPBest Management Practice.
If my site provide the truck wheel washing and inspection plan for this activity, will it be qualify as a measure for reducing Air with dust particulate matter?
I just got the comment to provide the clear evidence of prevention of polluting the air with dust and particulate matter. Will this truck wheel wasing comply with this comment?
Wheel washing does not control dust erosion. You need to come up with a watering shcedule, use tarps over stockpile areas to prevent wind uptake, etc.
So, if i have the watering schedule around the site area twice a day, will this be qualified without tarps (too expensive)?
I am not familiar with your climate, as this will dictate the watering schedule.
I would go with some form of language on the plan that states access to/from the site will be through the construction entrance, and the site will be kept free from dust by the use of on-site watering trucks on an as needed basis, or as required by the local conservation district (or similar agency in your jurisdiction).
We intend to erect a sign board at the construction site entrance. "THIS IS A LEED SITE". Is this against the USGBC guidelines? Some colleagues say since it does not say that this is a LEED certified site, there wouldn't be any issues.
KC, there are LEED policy documents which address legal and trademark points like this. Without referencing them, I would recommend not using such signage. Although it doesn't say that it is LEED certified, it's not clear what it does intend to say or mean. Someone unfamiliar with LEED (i.e. most of the general public) could easily assume that the site was certified or had some LEED imprimateur, when in fact it is at this point probably no more than registered and pursuing various credits.
Again, I didn't review the LEED policies before posting this, but I would think that language such as "XYZ project is attempting LEED Gold certification" or "A LEED-registered project" or "We're going for LEED—we need your help!" would be more accurate and reflective of a message appropriate for this stage in the work.
See the link below for official policy, page 25 covers registered projects:
You CAN say, for example, "This project is registered under the LEED®
green building certification program." But not "this is a LEED project."
Can we submitt in LEED Online our ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation Plan in other language different than English? for example in Spanish?
There is guidance about this somewhere... I can't remember where. Basically you need to translate to English any documentation that is essential to a reviewer seeing that you've met LEED requirements. In the case of an ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation plan, I'm not sure where that falls. You might contact GBCI for clarification. Let us know what you learn.
Once we have this category addressed can we submit this category only or do we have to submit all categories at one time?
Tim, you can submit all your prerequisites and credits at once ("combined" submittal), or split them into Design and Construction submittals. To know which credits are eligible for the earlier design submittal, we have that information in our Documentation Toolkit.
We are working on a project in Costa Rica where the access road is a dirt road. We are using a vehicle tracking control as part of oue ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation plan during the construction process, however all internal streets inside the project will be dirt roads. Were are planning to build open grid pavement streets for the project operation. Do we really need to use a vehicle tracking control wile both roads are dirt roads?
So the access road to the project site is a dirt road, correct? VTOs are used for construction entrances that intersect with a paved roadway to prohibit sediment from being tracking onto the paved roadway. I see no need to provide a VTO (if I understand your project correctly), but just make sure this is spelled out on your E&S Plan and narrative.
This is not to say that you shouldn't employ other appropriate conservation measures, you will probably dealing with a lot of dust. I would have a decent wet-down schedule in place.
We have a construction site with an existing 40 ft asphalt driveway & entry/exit, which we will be using as our only construction entry point. Would an existing asphalt driveway qualify as legitimate sediment tracking solution, or will we need to provide crushed gravel/filter fabric or tracking mats?
I've never seen this approach fly, unless you can make the argument that there will never be contact with disturbed soil.
My firm has built an Athletic Field house for a local school district. SWPPP and ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation plans were created and followed accordingly. Now here is where it gets complicated. The whole parcel of land (school building, parking lot and adjacent fields) prior to any demolition or construction was subdivided and all but 3.2 of the 8 acres was sold to the Town. Our LEED site is only our proposed building and a little bit of the surrounding grass areas on the 3.2 acres( this is documented in a separate drawing being uploaded for the credit). The Town has developed the rest of the parcel with athletic fields, a playground, parking (including parking on the school owned portion of the parcel)and a small maintenance building also housing small toilet rooms. The Town funded and built all of this including the parking lot for our LEED building since the parking lot served their portion of the parcel as well. The Town funded the design of the SWPP/ESC for the entire parcel of land including our LEED building. Therefore, all of the SWPPP/ESC plans are for the entire parcel of land not just our LEED site. Since there was an existing building on the Town's portion of the parcel there were several stages of SWPPP/ESC plans designed and implemented to suit which phase of demolition/construction was going on at that point in time. All calculations are also done for the parcel of land as a whole not just our LEED portion. My questions are as follows:
1. Can the SWPPP/ESC plans be submitted as they are with the whole parcel of land on them? Can it be as simple as just highlighting our LEED site area on their SWPPP/ESC plans but, leaving the whole document in tact otherwise?
2. If question #1 if the asnwer is yes they can be submitted as a whole parcel of land then for credit SS6.1 should we be entering water runoff calculations for just our LEED site (which contains no drainage wells etc. since the parking lot is not included in the site) or the site as a whole including the Towns portion?
Note: The Town did not fund any kind of LEED certification for their portion of the site. Only the school district is trying to achieve LEED certification for their building.
I would submit the E&S plan, as approved by your local Conservation District. For question #2, if your stormwater facilities for your project are located on a campus, but not necessarily on your site, submit the campus-wide calcs. This was in a CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide at some point, I believe Amy references this in a post on the 6.1 forum.
I got a rejection from the LEED reviewer for a similar problem. Our SWPP plan covered an entire city block with three different construction projects. The LEED Reviewer rejected that plan, saying it did not cover the actual LEED project (although it did show all of the erosion controls required on the LEED project!) We are going back to the Civil Engineer and asking for a drawing that just shows the LEED boundary and all erosion control measures required within that boundary only. It won't require anything different than the drawing the LEED reviewer already saw. I would try to obtain an ESCAn Erosion and Sedimentation Control (ESC) plan is a collection of measures designed to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation or SWPP plan that just shows the area within your LEED boundary.
Can anyone tell me if there is a LEED NC credit that would "reward" a project for using Compressed Natural Gas in excavation and other construction equipment? I can not decide what this might fall under other than this pre-requisite and I'm not sure it even helps here. Thank you.
Janna, I don't think this is relevant in helping you earn SSp1, although it doesn't hurt. I don't see another credit where it's relevant. However, you should check out the new pilot credit on clean construction, which you could use for an innovation point.

Minimizing construction impacts and carrying out a low-impact development strategy will help to achieve this credit.
The ESC and stormwater plan developed for construction will be the basis of plans for the management of stormwater onsite (contributing also to SSc6.2).
