Assessment of Stormwater Runoff, MS4

2018 Industrial Storm Water General Permit Amendment

The California statewide National Pollutant Discharge Elimination System (NPDES) Industrial Storm Water General Permit regulates the discharge of water associated with industrial activity.  On November 6, 2018 the State Water Board amended the General Permit to new requirements. These additional requirements become effective on July 1, 2020.

The amendments include:

  • Sufficiently Sensitive Test Methods – requiring a site pollutant source assessment for applicable Total Maximum Daily Loads (TMDL)
  • TMDL Implementation – including requirements for facility operators to collect industrial storm water samples for pollutant analysis and assessed for compliance
  • Additional State options incentivizing on-site or regional storm water capture and use

EEC Environmental specializes in the analysis, evaluation, communication and remediation of storm water runoff. 

In light of these amendments, EEC is available for related services including:

  • Conducting a site pollutant source assessment for applicable TMDLs.
  • Reviewing previous sample results to determine if the current BMPs implemented are adequate for meeting the TMDLs
  • Recommending additional BMPs both general and advanced that can help to meet the TMDL
  • Assist in responding to any enforcement actions taken by the Regional Water Quality Control Board.

The complete Amendment Fact Sheet is available as a download here.

Environmental Technical Assistance Opportunity

Three Maryland food processing facilities to receive free assistance

The Maryland Department of the Environment has contracted with EEC Environmental to provide environmental opportunity assessments and technical assistance to three food or beverage manufacturing/processing facilities in Maryland.  EEC Environmental, a nationally recognized environmental consulting firm, will work directly with three selected facilities to identify opportunities and solutions for improving energy and water use efficiency, reducing chemical usage, hazardous and non-hazardous waste reduction, wastewater reduction and process optimization.  The purpose of these visits is not to advise on environmental compliance issues, but rather to identify voluntary actions that will reduce environmental impacts and reduce costs for the facility.

The participating organizations will be asked to provide facility access and information

to the EEC Environmental consultants and in exchange will receive the following services free of charge: 

  • A facility-wide audit to identify opportunities that increase the efficiency of resource use, reduce waste and related environmental impacts and save money.
  • A written report identifying opportunities related to energy efficiency, water conservation, waste reduction, recycling, composting, procurement, transportation, and cleaning.
  • Assistance in prioritizing these opportunities based on return-on-investment, payback period, environmental impact, feasibility, and owner/management priorities, and an outline of next steps for implementation.

Interested companies should contact the following individuals as soon as possible, but no later than June 1, 2020 in order to take advantage of this valuable program.

Industrial General Permitting

Most new construction, development and upgrade projects require some sort of industrial general permitting assessment.  Sometimes abbreviated as IGP, this permit puts regulations in place for how stormwater is discharged from industrial sites.

Facilities Subject to Regulations

Not all facilities are subject to regulations regarding stormwater discharge, or need an industrial general permit. However, some of the types of facilities that are usually subject to these regulations include:

  • Hazardous waste management
  • Landfills
  • Manufacturing
  • Mining
  • Recycling
  • Sewage or wastewater treatment
  • Transportation

This is by no means an exhaustive list. The IGP may differ as you move across state lines as some states prioritize natural resource management more than others. The facility’s Standard Industrial Code (SIC) determines if coverage is required.  If your facility has no outside exposure of the potential pollutants, then your facility can obtain non-exposure certification (NEC).

What Happens if Your Business or Project is Out of Compliance?

It is the responsibility of local government agencies to identify and report any facilities that are out of compliance. However, older establishments are more likely to be out of compliance than new organizations.  This is because many government agencies now check business license applications to see if you will need an industrial general permit, and will usually inform you at that time. If you are found out of compliance, you may be significantly fined or have the project put on “hold”.

How to Verify if Your Facility is in Compliance

The process of verifying your organization’s compliance status varies from state to state, or even across city and county lines. As a result, it is important to have professional consultants on your team, like the environment compliance experts at EEC Environmental.  We are experienced in all environmental compliance and permitting applications, and assist our clients in navigating complex industrial permitting laws.

Should we find that you are out of compliance, we will also assist you with getting your permit in place, whether it requires a new application or a renewal.  For more information on how we can assist you, contact our corporate office at (714) 667-2300 or send us a detailed message via the contact form on our website.  Industrial general permits can be daunting, let EEC Environmental help you navigate.

What Is Bioremediation?

What Does Bioremediation Technology Entail?

Bioremediation is the method of cleaning up groundwater, soil, and subsurface contaminations using biological organisms. Bioremediation specialists treat pollutants, such as oil, pesticides, solvents and various petroleum products, through mimicking and stimulating nature’s biodegradation processes.

In nature, microbes such as yeast, bacteria and fungi feed on contaminants and release water, CO2, ethene and other harmless gases as byproducts. Bioremediation specialists employ this organic occurrence to reduce or eliminate pollutants from different mediums in the following ways:    

  • Bioaugmentation is the method of supplementing the appropriate variety of microbes indigenous to the groundwater and soil. For the microbes to thrive and eat pollutants most effectively, certain conditions are required, such as a suitable temperature, oxygen and the addition of nutrients and amendments, e.g., vegetable oil or molasses. The treatment may be performed in situ, meaning in place, or, if conditions are not ideal, ex situ, meaning above ground. Ex situtreatment is achieved through the pumping polluted groundwater or excavation impacted soil. Once removed from the subsurface treatment would occur. Read here to learn more on the topic.
  • If there is little or no biological activity at a site, exogenous microbes can be introduced and enhanced to degrade the contamination.
  • Some microbes require oxygen in the environment to function, while others bioremediate in an anaerobic, or oxygen-free, environment.

Are There Any Side Effects?

Bioremediation uses microbes that naturally occur in groundwater and soil, harmlessly stimulating chemicals, nutrients and amendments, causing no damage to onsite personnel or the surrounding community. Samples from the treatment site are frequently tested by bioremediation specialists to maintain balance and monitor progress. After treatment, the microbes die off and leave minimal byproducts such as water and gases. In comparison with several other methods, onsite bioremediation offers a cheaper and less disruptive way to clean up a site.       

What Is the Treatment Length?

The duration for remediation is site specific. It can range from a few months to a few years, depending on the size of the contaminated site, the favorability of the host and surrounding environments, contaminant concentration, in situ or ex situ methods, and cleanup after ex situ treatment.

Why Choose EEC?

Selecting an appropriate remedial approach and action plan is crucial to clean up a site and meet regulatory closure requirements.

Soil and Groundwater Remediation System Design

As available land for construction and redevelopment in large urban environments becomes more and more scarce, the once terrifying idea of redeveloping an environmentally impacted site has now become a tremendous opportunity to make a significant return on investment. As savvy investors realize these opportunities, soil and groundwater remediation is something many developers and investors face on a daily basis. The good news is that we have entered an era when there is an ever-expanding list of options to clean these sites at greatly reduced cost and time frames than in early years of environmental industry.

Sources of Soil and Groundwater Contamination

Causes of soil and groundwater pollution are varied, and include release from landfills, industrial operations, sewage, mining, nearby sanitation systems, fuel stations, dry cleaners, and liquid waste from wastewater treatments. Groundwater may be contaminated with volatile and semi-volatile chemicals, pathogens, radioactive material, metals and organic compounds.

Soil and Groundwater Remediation Options

  • Physical treatments can include excavation of impacted soil, soil stabilization, air sparging, soil vapor extraction, dual phase extraction, and pump and treat with carbon adsorption.
  • Biological treatments comprise biosparging, bioventing, bioslurping, in situ anaerobic bio-augmentation and phytoremediation.
  • Chemical treatments, chemical precipitation, in situ chemical oxidation, ion exchange, surfactant enhanced recovery, membrane separation and oxygen and ozone gas injections.

The treatment method should be chosen based on the contaminants specific to the site and other site-specific factors. For example, pollutants such as tetrachlorethene (better known as the dry cleaning solvent PCE or PERC), trichloroethene, benzene, ethylbenzene, poly-nuclear aromatics and vinyl chloride can be remediated through enhanced or natural aerobic and/or anaerobic degradation, carbon adsorption, insitu chemical oxidation, or in situ or exsitu thermal treatment. Other like metals and pesticides are more effectively addressed by soil removal or stabilization.    

Combination of New and Old Techniques

Offering clients comprehensive site investigation, remedial feasibility expertise, and remedial design and implementation, EEC Environmental has remained on the front line of the newest remedial technologies while also utilizing time-tested techniques.
