SPCC Rule Exemption For Milk and Milk Product Containers

The U.S. Environmental Protection Agency (EPA) has exempted milk and milk product containers from the Oil Spill Prevention, Control and Countermeasure (SPCC) rule, potentially saving the milk and dairy industries more than $140 million per year. Based on input from the milk industry, EPA had previously delayed SPCC compliance requirements for milk and milk product containers until the mandated regulatory process could be completed. In January 2009, EPA proposed the rule to exempt milk containers from the SPCC rule.

The SPCC regulations require facilities with the capacity to store more than the threshold quantity of oils and fats to create and implement plans to prepare, prevent and respond to spills. The current exemption for milk does not apply to fuel oil and other applicable oils stored on farms; farms that store above the regulatory threshold of fuel oil and other applicable oils are covered under the SPCC.

Applying for New Texas TPDES Multi Sector General Permit

The TCEQ is proposing to issue the new TPDES Multi Sector General Permit (MSGP) in July 2011 with the effective date of August 14, 2011. The TCEQ plans to send renewal notification letters to inform current permittees that facilities who want to renew permit coverage have until November 21, 2011 to submit the required application form (NOI or NEC). Current permittees who do not want to renew coverage must submit an NOT before September 1, 2011, to avoid the $200 annual water quality fee.

According to TCEQ, renewal application forms will not be available nor accepted before the permit effective date of August 14, 2011. If an operator submits an NOI or an NEC before the effective date of the permit, a new authorization under the existing permit will be processed.

Proposed Texas Multi Sector General Permit For Industrial Storm Water Discharge

The Texas Commission on Environmental Quality (TCEQ) is proposing to renew TPDES Multi Sector General Permit (MSGP) TXR050000, issued August 14, 2006, which authorizes the discharge of storm water associated with industrial activity. The draft MSGP specifies which facilities must obtain permit coverage, which are eligible for exclusion from permit requirements, which may be automatically authorized, and which may be required to obtain individual permit coverage.

Some of the key changes to the existing MSGP include:

  • Added a section to the general permit stating that certain types facilities are covered under the general permit without submitting an NOI, nor having to implement a SWP3 according to the requirements of the general permit, provided that certain specific permit conditions are met
  • A new option for transportation facilities (land transportation and warehousing, water transportation, and air transportation) to include storm water discharges from material handling and storage areas in their MSGP authorization.
  • Authorization for contaminated storm water discharges from active landfill cells described by industrial activity codes HZ (hazardous waste treatment, storage, and disposal) and LF (landfills and land application sites) that are subject to 40 CFR Part 445, Subparts A and B.
  • Changes to requirements for paper application forms, and increased the application fee by $100.00 for operators submitting a paper NOI or NEC form.
  • Changes to benchmark sampling, including:
    1. Revised benchmark levels based on data that was submitted during calendar years 2007 and 2008.

    2. Added benchmark sampling requirements in Sector AD (Miscellaneous Industrial Activities) for pollutants commonly regulated in individual storm water permits: pH, COD, TSS, and oil and grease.
    3. Added a waiver option for benchmark sampling during Years 3 and 4, if sampling during Years 1 and 2 demonstrates that the annual average result for all benchmark parameters is below the benchmark level for the regulated sector.
    4. Revised reporting requirements so that Years 1 and 2 data would be submitted to TCEQ and Years 3 and 4, if collected, would be retained on site, except that any annual average result exceeding a benchmark level must be submitted to the TCEQ.
  • Revision of permit language regarding “representative storm event” changed to “qualifying storm event,” to clarify that a precipitation event is considered representative (or qualifying) based on the fact that it produces a discharge, rather than based on the measured amount of precipitation (i.e., previously, a representative storm event would include at least 0.1 inch of measured precipitation).
  • Additional revisions within several specific industries in Part V of the draft MSGP, including:
    1. Removed effluent limits for runoff from coal piles that are not associated with a steam electric power generating facility.
    2. Added or revised industry-specific requirements for most industrial sectors to be consistent with EPA’s 2008 MSGP.
  • Revised the section “Impaired Water Bodies and Total Maximum Daily Load Requirements” to address new and existing discharges to impaired water bodies listed in accordance with Section 303(d)(1) of the federal Clean Water Act.

Storm Resistant Shelter Requirement Under TCEQ Proposed No Exposure Exemption

The Texas Commission on Environmental Quality (TCEQ) is proposing to renew TPDES Multi Sector General Permit (MSGP) One of the key changes under the proposed MGSP will be the requirements to meet the No Exposure Exemption.

Facilities regulated under the MSGP may be excluded from permit requirements if there is no exposure of industrial materials or activities to precipitation or runoff. To qualify for this conditional exclusion from permit requirements, the operator of the facility must certify that industrial activities and materials are isolated from precipitation and runoff by storm resistant shelter (there are certain exceptions to the requirement for a storm resistant shelters). The certification must be submitted to the TCEQ on a No Exposure Certification (NEC) form, or other approved form.

Storm-resistant shelters include buildings or structures that have complete roofs and walls, as well as structures with only a top cover but no side coverings, as long as the materials or activities under the structure are not otherwise subject to any run-on and subsequent runoff of storm water, or mobilization by wind.

Facilities operating under a conditional no-exposure exclusion are subject to inspection by TCEQ to determine compliance with the exclusion. In addition, operators of facilities that qualify for this exclusion and that discharge storm water to a municipal separate storm sewer system (MS4) must provide a copy of their NEC form to the MS4 operator, even if not required by the MS4.

Qualified SWPPP Developer & Qualified SWPPP Practitioner Requirements Under Draft California Permit

UPDATE: On July 16, 2012, an updated draft was released. Click here for a summary of the revised draft ICP

On January 28, 2011, the California State Water Resources Control Board released its draft General Permit for stormwater discharges associated with industrial activities. The draft NPDES permit proposes several changes from the existing California General Permit.

One of the important changes will be especially significant for facilities that have in the past prepared their own stormwater pollution prevention plan (SWPPP). Under the proposed permit, all dischargers will need to appoint a Qualified SWPPP Developer (QSD) to prepare, write, and make any revisions to the SWPPP, and appoint a Qualified SWPPP Practitioner (QSP) to help implement the SWPPP.

The minimum requirements to become a certified Qualified SWPPP Developer includes have one of the following registrations for certifications, and appropriate experience, as required for:

  • California registered professional civil engineer;
  • California registered professional geologist or engineering geologist;
  • California registered landscape architect;
  • Professional hydrologist registered through the American Institute of Hydrology;
In addition, the QSD must successfully complete the State Water Board-sponsored or approved QSD training course within one year after the effective date of this General Permit.

Unless a facility has a registered engineer, geologist, landscape artitict, or professional hydrologist on staff, facilities subject to the permit will need to contract outside professional services to prepare, certify and update the SWPPP.

The minimum requirement to become a certified Qualified SWPPP Practitioner is to successfully complete the State Water Board-sponsored or approved QSP training course within one year from the effective date of the General Permit.

Numeric Action Levels, Numeric Effluent Limits, and Corrective Action Triggers In California Draft Permit

UPDATE: On July 16, 2012, an updated draft was released. Click here for a summary of the revised draft ICP

On January 28, 2011, the California State Water Resources Control Board proposed a draft industrial stormwater discharge general permit. The draft General Permit amends a number of the existing requirements for permitted facilities and adds some new requirements.

One of the more significant changes to the California General NPDES Permit is the incorporation of quantitative Action Levels and Effluent Limits which could apply to any discharger:


Numeric Action Levels (NALs) are derived from the US EPA Multi-Sector General Permit’s benchmarks, and are used as numeric thresholds for corrective action. Exceedances of an NAL are not a violation of the permit; however, exceedance of specific NAL Corrective Action Triggers requires the facility to enter into Level 1 Corrective Action.

[More information on US EPA benchmarks, and comparison to historic industrial sector monitoring results]


Numeric Effluent Limits (NELs) are could also apply to any facility. Dischargers in Corrective Action Level 3 (see below) are subject to a numeric effluent limitation (NEL) that will be the same value as the applicable pollutant NAL. A daily average exceedance of the NEL is a violation of the General Permit and may subject the discharger to mandatory minimum penalties.

NAL Corrective Action Triggers are defined in the draft general permit as follows:
1. The Daily Average (DA) for any one constituent exceeds the NAL value for two or more storm events of a reporting year, or;
2. The DA for any two constituents exceed the NAL values for any single storm event within a reporting year, or;
3. The concentration for any one constituent exceeds 2.5 times the NAL value for any one individual or allowable combined sample (or is more than one pH unit outside the NAL pH range)

In the event that any of the NAL Corrective Action Triggers are met, the facility will need to complete Level 1 Corrective Actions. The need to do further corrective actions will depend on subsequent monitoring results.


Level 1 - Operational Source Control Corrective ActionsUpon the first occurrence meeting any of the NAL corrective action triggers, the discharger will be required to valuate areas of the facility to identify where additional operational source control BMPs and/or SWPPP implementation measures are necessary to prevent or reduce pollutants in storm water discharges in compliance with BAT/BCT. Based upon the facility evaluation, the facility will certify that the pollutant source(s) have been identified and 1) additional operational source control BMPs and/or SWPPP implementation measures have been included in the SWPPP , 2) no additional operational source control BMPs or SWPPP implementation measures are required , or 3) pollutant source(s) causing the exceedance are not related to the facility’s industrial activities. A Level 1 NAL Exceedance Evaluation Report will need to be prepared and submitted.
Level 2 Structural and/or Treatment Corrective ActionsIf in any subsequent reporting year the sampling results meet an NAL corrective action trigger, the discharger is require to take addition action. If the NAL corrective action trigger is for a constituent that had not been included in a previous Level 1 NAL Exceedance Evaluation Report, the discharger go through Level 1 Corrective Actions.
If the NAL corrective action trigger is for one or more of the constituents previously addressed in a Level 1 NAL Exceedance Evaluation Report, the discharger would need to evaluate and select additional structural source control BMPs and/or treatment BMPs with the goal of achieving the applicable NAL value(s) in future discharges. A Level 2 NAL Exceedance Evaluation Report will need to be prepared and submitted and more frequent monitoring is required.
Level 3 Imposition of Numeric Effluent LimitsIf in any subsequent reporting year the sampling results meet an NAL corrective action trigger for the same constituents subject to the Level 2 corrective actions, the discharger shall the applicable NAL(s) will become an NEL(s), and starting October 1 of the following compliance year, the discharger will be required to sample every qualifying storm event.
