Environmental Compliance Tips 2018

September: RCRA Waste

Can I combine hazardous waste from two different facilities?

Under specific conditions, Very Small Quantity Generators of Hazardous Waste (formerly Conditionally Exempt Small Quantity Generators) can combine their waste with the Large Quantity Generator if control is under the same person.  See RCRA Update

August: MOU between EPA and DOT

At a given facility, when is a tank truck delivering fuel (or other oil) regulated by DOT rather than EPA’s SPCC Rules?

EPA and DOT established a memorandum of understanding in 1971 to clarify jurisdictional issues such as this one.  In essence, DOT has authority over “transportation-related facilities” while EPA regulates “non-transportation facilities.”  In the example of the tank truck delivering fuel, the truck is not regulated by EPA when it is in transit to the facility.  Upon arrival, the parked tank truck and the loading/unloading activities are subject to the SPCC Rules (assuming that the facility is regulated).  If the tank truck still contains fuel when parked overnight at its home base, and the home base is required to have an SPCC, the tank truck would be subject to the SPCC Rules for the duration that it’s parked.

July: SPCC

When designing secondary containment for your SPCC, don’t forget to consider this.

“Squirt Protection.”  The design of secondary containment should take into consideration a potential rupture of the tank and squirting liquids.

One suggestion is to use the difference between the tallest container height and the wall height as the minimum distance between the stored containers and the edge of the containment area.

June: TRI Reporting Changes

Were there changes to TRI reporting for this year (reports due July 1st)?

Yes. Among the published changes are the following:

  • A new TRI chemical category was added (Hexabromocyclododecane (HBCD))
  • TRI NAICS Codes were adopted
  • Updated De Minimis levels for several chemicals

See Important Information for Reporting Year 2017.


Do I have to report under Section 313 of EPCRA?

You must report under Section 313 of EPCRA (aka Toxic Chemical Release Inventory or TRI) if all of the following apply to your facility:

  • You have 10 or more full-time employee equivalents (20,000 hours or greater)
  • Your facility is classified with an applicable NAICS (See Table I. NAICS Codes)
  • Your facility manufacturers (includes importing), processes or otherwise uses any of the EPCRA Section 313 chemicals in quantities at or greater than the threshold for a calendar year.

April SQG Reporting

When does the “re-notification requirement” for Small Quantity Generators (SQG) begin?

In 2021 (September 1st), SQGs will be required to a submit EPA Form 8700-12. This form provides notification to the EPA, or state if authorized under RCRA, regarding your hazardous waste activities. SQGs will be required to complete the form every four years. Currently, only Large Quantity Generators are required to submit the form (on even numbered years).

March: SPCC Oil Storage “Capacity”

I have the capacity to store more than 1,320 gallons of oils above ground, but never store that much. Do I need a SPCC Plan?

Assuming your facility is regulated, and the stored substances are regulated, then, yes you are required to prepare and implement a Spill Prevention Control and Countermeasure (SPCC) plan.

The SPCC Plan rules are based on the aggregate storage capacity. When calculating total storage capacity, remember to include manufacturing and operational electric equipment (transformers) if their oil storage reservoir capacity is greater than 55 gallons.

February: EPCRA Reporting Changes Effective 2018

What has changed for EPCRA reporting for 2018?

Starting in 2018, the hazard categories for each chemical must be included in the report. We discussed these changes last year (Changes in SARA Tier I and Tier II Chemical Reporting Regulations).

January: CERCLA Reportable Quantities

If I have a chemical release at my facility, what do I consider to determine whether the release is reportable under CERCLA?

1. Is the chemical a CERCLA Hazardous Substance?

2. Is the release amount (in a 24-hour period) at or above the reportable quantity?

3. Are there other sources of this chemical at my facility that could have been released during the same time period?

If you have a reportable release, you must notify the National Response Center immediately.

Environmental Compliance Tips 2017

December: SPCC Requirements for Milk Storage

Is milk considered an oil under the Spill Prevention Control and Countermeasure Plan (SPCC) Rules?

While there was dispute over regulating the storage of milk (in excess of threshold quantities) due to fat (oil) content, the Environmental Protection Agency specifically exempted milk from the SPCC requirements in 2011. For more information on environmental regulations affecting agriculture, see The Changing Environmental Regulatory Landscape for Agriculture.

November: Small Quantity Generators

The classification of Conditionally Exempt Small Quantity Generators (CESQG), under RCRA, was recently changed to what?

The USEPA made several changes to RCRA, including changing the name of CESQG to Very Small Quantity Generator (VSQG). See our August 17th blog for more information on the changes to RCRA. NOTE: for those states designated to implement the RCRA program, these changes must be adopted by the states.

October: SPCC Self Certification

Can I Self Certify My Spill Prevention Control and Countermeasure (SPCC) Plan?

Yes, if you meet the following criteria:

The facility aboveground oil storage capacity is 10,000 gallons or less. And,

In the three years prior to your SPCC Plan being certified, there has been no discharge to navigable waters. Discharge is defined as a single release of greater than 1,000 gallons or two releases greater than 42 gallons within any 12-month period.

If these criteria are met, the facility qualifies for self-certification.

  • Tier I if no individual Aboveground Storage Tank (AST) greater than 5,000 gallons.
  • Tier II if any AST is greater than 5,000 gallons.

September: NPDES and Secondary Containment

Is discharge of precipitation that accumulates in secondary containment structures allowed under NPDES stormwater discharge permits?

Maybe. In some states, liquids accumulated in a secondary containment structure can be discharged to the ground surface or storm sewer following inspection and/or characterization. In many states, however, discharge from secondary containment structures is strictly prohibited in the permit conditions unless the owner/operator has obtained a permit for the discharge. We recommend that you check the conditions of your NPDES stormwater discharge permit to be sure.

August: SPCC

Do the SPCC Rules apply only to petroleum products?

No, oils of any type are regulated. This includes, but is not limited to, petroleum, fuel oil, waste oil, vegetable oils, and oils of animal, fish, or marine mammal origin. The USEPA does not publish a list of regulated oils. If you have a question whether a particular material is subject to the SPCC rules, consult the USEPA or a qualified professional engineer for a determination.

July: NPDES Stormwater

If my facility stores pallets outdoors, is this a potential violation of my NPDES stormwater discharge permit?

Containers, racks, and other transport platforms (e.g., wooden pallets) used with the drums, barrels, etc., can be stored outside providing they are contaminant-free.

While having contaminant-free pallets stored outdoors may not trigger a violation, if your facility has poor housekeeping, it may give reason for an inspector look harder into any other possible issues.

June: Pollution Incident Prevention Plan (PIPP)

Does the sulfuric acid contained in material handling-equipment batteries trigger the (Michigan) PIPP requirements?

Sulfuric Acid is a polluting material as defined by the PIPP rules. There is an exemption for small lead-acid batteries (less than 10 gallons of electrolyte solution); however, batteries used for fork lifts or Hilos are typically not exempt because of the size of the batteries. There is a narrowly-defined exemption for these larger batteries: “…by not exceeding …10 gallons or 100 pounds, and, where the sulfuric acid container, often referred to as a cell, is not hydraulically connected to other cells, is exempt from the Part 5 rules” (MDEQ Water Bureau Part 5 Rules Operational Guidance [POG#4]).


Is integrity testing of bulk storage containers required?


Integrity testing and routine inspection are required for aboveground bulk storage containers with a capacity of 55 gallons or more.

Integrity testing must be performed according to industry standards such as those published by American Petroleum Institute or Steel Tank Institute. For some containers, such as 55-gallon drums, visual inspection only may meet the requirements of the standards.

Environmentally-equivalent measures may be substituted for integrity testing when reviewed and certified by a professional engineer. More detail on environmental equivalence can be found in Chapter 7 of the USEPA SPCC Guidance for Regional Inspectors.

Note that oil-filled equipment is not a bulk storage container and is, therefore, not subject to the integrity testing requirements of the SPCC rule.

April: NPDES

Do I need an NPDES Stormwater Permit?

The requirement for a stormwater discharge permit will depend on a number of factors. In general, if you discharge your stormwater to the local publicly owned treatment works (POTW), a permit is likely not required. If you have a point source discharge of stormwater to a water of the United States, then it is more likely that you will need a permit. It will depend on your Standard Industrial Classification Code and whether outdoor storage or operations at the facility could contribute contaminants to storm water. Contaminants are widely defined under this regulation and include things like rust and sediment. Ultimately, check with your permitting authority (state, if authorized, or EPA).

It is worth noting that the municipal governments are beginning to assess businesses for stormwater discharges to POTWs (see Detroit, MI and Toronto, ON), and the charges can be significant.

March: RCRA

What is the definition of a RCRA empty container?

In general (not including acutely hazardous waste or compressed gas), “RCRA Empty” is when all wastes have been removed and no more than 2.5 cm or 1 inch of materials remain (see 40 CFR 261.7 Residues of hazardous waste in empty containers).

February: Extremely Hazardous Substance Reporting under SARA 302 vs 311/312

How does reporting of Extremely Hazardous Substances (EHS) differ under Section 302 and Section 311/312 of SARA?

Storage of EHS must be reported under both SARA Section 302 and Sections 311/312 if the storage amount is above the applicable threshold. However, the threshold can be different for the same EHS under the different sections.

Section 302 of SARA is a one-time notification of EHS at a facility based on Threshold Planning Quantities (e.g., the Sulfuric Acid TPQ is 1,000 lbs).

Section 312 of SARA is an annual submission due by March 1st each year based on Threshold Planning Quantities (e.g., the Sulfuric Acid TPQ is 500 lbs).

See the EPA’s List of Lists for details

January: SARA

How do the reporting thresholds differ between SARA Tier II and TRI reporting?

SARA Section 311/312 Tier II thresholds apply to the STORAGE of chemicals at any one time during the calendar year:

  • Extremely Hazardous Substance (EHS) at 500 pounds or the threshold planning quantity (TPQ), whichever is less
  • Gasoline at retail gas stations in USTs at 75,000 gallons
  • Diesel fuel at retail gas stations in USTs at 100,000 gallons
  • Other OSHA hazardous chemicals at 10,000 pounds

SARA Section 313 Toxic Release Inventory (TRI) thresholds apply to the USAGE of certain chemicals in a calendar year. Section 313 contains a specific list of reportable chemicals.

  • Chemicals manufactured, imported, or processed at 25,000 pounds/year
  • Chemicals “otherwise used” at 10,000 pounds/year
  • Persistent, Bioaccumulative, and Toxic (PBT) chemicals are at lower thresholds
