Industrial Activity (MSGP) Frequently Asked Questions (FAQs)

Can I transfer coverage under the MSGP when I sell the facility or change ownership of it?

No. If a facility is sold or the ownership otherwise changes, the current owners must submit a NOT to terminate their coverage and the new owner must submit a Notice of Intent and the $500 permit fee to obtain coverage.

Is my facility required to have permit coverage?

Stormwater discharges associated with industrial activity to surface waters of the State or to an MS4 are required to be covered under an NPDES permit. Most facilities are eligible for coverage under the MSGP for their stormwater discharges associated with industrial activity.  Some facilities are required to obtain an NPDES individual permit for their stormwater discharges associated with industrial activity if there is reasonable potential for the stormwater discharge to exceed limits in their previously issued NPDES individual permit.

A one-page description of “stormwater discharges associated with industrial activity” is available.

Can my facility be exempted from the requirement to obtain NPDES permit coverage?

Yes, some facilities may qualify for the conditional “no exposure” exclusion from the requirement to obtain NPDES permit coverage.  Effective June 1, 2001, industrial facilities that have no exposure of materials or industrial activities to stormwater may submit a “no exposure” certification to DEP and be excluded from the requirement to obtain NPDES permit coverage.  More information about the Conditional No Exposure Exclusion is available on this web site.

How do I obtain coverage under the Multi-Sector Generic Permit (MSGP)?

Apply for permit coverage online using iNOI or submit a complete paper NOI and fee of $500 to the NPDES Stormwater Notices Center and comply with the requirements of the MSGP.

How do I renew coverage under the Multi Sector Generic Permit (MSGP) for Stormwater Discharge Associated with Industrial Activity?

Coverage under the Multi-Sector Generic Permit for Stormwater Discharge Associated with Industrial Activity (MSGP) is effective for a period of five years. To renew coverage, the facility should reapply by submitting a new Notice of Intent (NOI) and appropriate fee. (DEP Form Number 62-621.300(5)(b). The fee is currently $500). Coverage under the MSGP is effective two days after the submittal of a complete NOI and appropriate fee. (Rule 62-621.300(5)(f), Florida Administrative Code).

Facilities must file a new NOI to renew coverage at least two days prior to the expiration date of their current permit. In order to allow adequate time for processing and confirmation, the Department recommends that facilities reapply at least two or three weeks prior to the expiration date of their permit.

When is my permit coverage effective?

Permit coverage is effective 2 days after the postmark date of your complete NOI and fee submittal.

How do I determine my facility’s Standard Industrial Classification (SIC) code?

The SIC code system is maintained by the US Department of Labor, Occupational Safety & Health Administration (OSHA) and is available for searching at www.osha.gov/oshstats/sicser.html.  Note also that SIC codes are typically required on other forms submitted to the government (e.g., Federal tax return, etc.) so you may look to those sources of information.

What is my monitoring code as required for the NOI?

The monitoring code to be entered on the NOI is determined by the permit requirements for the sector(s) of the MSGP that the facility is covered under.  That is, the “sector-specific” monitoring requirements.  The possible monitoring codes, as indicated in the NOI instructions, are:

1 =  Not subject to monitoring requirements under the conditions of the permit.
2 = Subject to monitoring requirements and required to submit data.
3 =Subject to monitoring requirements but not required to submit data.
4 =Subject to monitoring requirements but submitting certification for monitoring exclusion.

All sectors of the MSGP, except Sector S, require “quarterly visual examination” of stormwater discharges.  The visual examination is considered monitoring, however, analytical tests are not required and results are not required to be submitted to DEP.  The results of the quarterly visual examinations are required to be kept by the facility with their stormwater pollution prevention plan (SWPPP).  Therefore, the monitoring code if only quarterly visual examinations are required for the facility would be “3.”

Some sectors of the MSGP require quarterly analytical monitoring in years two and four of the permit cycle.  This monitoring is sometimes referred to as “benchmark monitoring.”  The results of the analytical tests for the benchmark monitoring are required to be submitted to DEP.  Therefore, the monitoring code if benchmark monitoring is required would be “2.”

A few sectors of the MSGP impose numeric effluent limitations.  The monitoring required to demonstrate compliance with the effluent limitations is called “compliance monitoring.”  Analytical results from compliance monitoring are required to be submitted to DEP.  Therefore, the monitoring code if compliance monitoring is required would be “2.”

Refer to the MSGP for sector-specific monitoring requirements for your facility.

How do I report analytical monitoring results (if benchmark/compliance monitoring required)?

Reporting of results is done using sector-specific Discharge Monitoring Reports (DMRs) that are available for downloading.  The NPDES Stormwater Notices Center will also provide you with the DMRs (and DMR instructions) along with your coverage confirmation letter, or under separate cover at a later date.  You will need to make copies of the DMRs to use for each monitoring event.

Where do I send the DMRs?

Send completed DMRs to:
Florida Department of Environmental Protection
NPDES Stormwater MSGP DMR, Mail Station #2511
2600 Blair Stone Road
Tallahassee, Florida 32399-2400     

My facility is in a sector that requires benchmark monitoring.  When am I required to monitor?

Benchmark monitoring is required in years two and four of your permit coverage.  For facilities that obtain permit coverage through the end of 2001, year two is 2002 and year four is 2004.  For facilities that obtain coverage in 2002, year two is 2003 and year four is 2005, and so on.  Quarterly sampling is required during your monitoring year(s).  The quarters are calendar quarters (i.e., Jan.– Mar., Apr.– Jun., Jul.– Sep., and Oct.– Dec.).  You are required to obtain at least one sample, if you have a qualifying discharge event, during each quarter, and record each sampling event on a separate DMR (i.e., “Q” DMR).  If there is no qualifying discharge event for a given quarter, you will need to complete a DMR for that quarter with the “no discharge” indicator block marked.  After the end of the monitoring year, results from the four quarterly sampling events are to be averaged and recorded on a separate DMR (i.e., “A” DMR).  If the annual average results from year two monitoring are below the cutoff concentrations for your sector, benchmark monitoring in year four is not required.

What is the deadline for submitting my benchmark monitoring DMRs?

DMRs must be submitted by March 31 of the year following the monitoring year.  For instance, if 2002 is your year two monitoring year, DMRs are due by March 31, 2003.

Do I have to address the Endangered Species Act (ESA) or National Historic Preservation Act (NHPA) provisions in my SWPPP?

No.  The provisions of the MSGP regarding the ESA and NHPA are applicable only in areas where EPA is the NPDES Permitting Authority.
