Toxic Mold

What Toxic Mold Is

Mold or fungus are considered toxic if they cause one or more of the following health problems (www.cdc.gov). First, are burning or irritated eyes. Second, is runny nose, coughing, sneezing, wheezing, or a few other upper respiratory problems. Third, are headaches or fatigue. Fourth and last, are nausea and cognitive (brain) problems.Types That Are Toxic

Black Toxic Mold

Black toxic mold refers to a genus or type of mold called Stachybotrys. Further, it typically refers to a species called chartarum. But how did it get this famous reputation? Firstly, it is well known because of highly publicized court cases. Secondly, it was identified in a few highly publicized public health cases. And, finally, the media has given it a lot of attention. As a matter of fact, it received so much attention that some people believe it is the only toxic fungus. But, that is simply not true! (https://www.escflorida.com/mold-myths/)

Other Mold that is Toxic

There are lots of other types or genera of mold which are toxic. This is well documented in the scientific literature. Some of the common ones are Penicillium, Aspergillus, Cladosporium, and Chaetomium. These grow actively both outside and inside buildings.

Causes of Toxicity

These types of mold are toxic because their spores, toxins, or chemicals can cause one or more of the health problems above. These problems may only involve one person in a building with hundreds of occupants. However, that one person experiences a definite health problem from the mold.

Why does that mold not cause a health problem for that same person outside the building? First, the mold population may be much larger inside. Second, there may not be enough fresh air ventilation inside. Third, the mold may be forming colonies on building materials or contents close to that person.

The difference inside is usually due to water. Firstly, the water can come from leaks around windows, doors, roofs, ice makers, and more. Secondly, the water can come from the air conditioner not running or malfunctioning. This can result in elevated humidity, condensate drain pan overflows, and more. Third, the water can come from floods. This may be from weather outside, toilets, and more. As a result of this water in a building, the mold grows and becomes much different in its population and the types.

Certain types of mold are toxic because they cause health problems for some people. There are many types of such mold in addition to the black mold. Water is usually the cause of the unique mold inside a building. In any event, ESC can help determine the cause and the solution for your toxic mold. Feel free to contact us today

Background for Construction NPDES Stormwater

This is the third post in a series on Construction NPDES Stormwater Permits and stormwater plans and it deals with different types of construction controls for stormwater pollution (see https://www.escflorida.com/construction-stormwater-npdes-permits/ & https://www.escflorida.com/construction-pollution-npdes-stormwater/). First, we discussed the permits in detail. Second, we discussed the types of pollution which can occur on construction sites. Third, we now turn to discussing the controls.

Types of Pollution

In our last post on construction pollution, we identified the following main types of pollution. First, are particles created by digging, grading, drilling, and dewatering. Second, is existing contamination from past usage and it includes gas, diesel fuel, oil, hazardous wastes, and agricultural materials. Third and finally, is the type of pollution which comes from construction activities on site. It may include gas, oil, diesel fuel, paint, solvents, grease, fertilizer, pesticides, and sewage.

Types of Construction Controls

The types of controls are as different as are construction sites. However, they fall into four groups. Firstly, are barrier controls which block, divert, or filter stormwater runoff. This group includes black silt fence, earthen berms, vegetated screens, sand bags, turbidity curtains, and hay bales. Secondly, are drainage controls. In this group are pipes, swales, ponds, ditches, settling basins, drainage weirs, and sediment traps. Thirdly, are covers. Included are seed, sod, straw, mulch, pavement, geo-textiles, sidewalks, and curbs. Fourthly and finally, are practices and procedures. Included in this group are housekeeping, hazardous material storage and usage, portable toilets, fuel tanks, oil, grease, paint, waste disposal, and solvents.

Selection of Construction Controls

The selection of controls depends on several factors. First, is the size of the site. Second, are the development plans for the site. For example, if there are 500 acres to be clear cut, there will be site-wide erosion and sediment controls compared to disturbance of 1/2-acre of a 5 acre site. Controls in the latter case will be more limited and confined to that portion of the site being developed. Third, is the construction schedule. A very short schedule will minimize the time for controls to be in place. On the other hand, a long schedule will require long-term controls, maintenance, and most likely replacement. Fourth and finally, are miscellaneous factors such as the numbers of workers, subcontractors, and equipment on the site; the nature of soil disturbing activities; waiting time for regulatory inspections; quantities and locations of hazardous materials; and many, many more.

Inspect and Fine Tune

From the start, embrace controls as ongoing and requiring maintenance and possible replacement. Complete weekly and post-rainfall inspections as required by your stormwater plan (https://www.epa.gov/npdes/stormwater-discharges-construction-activities). This plan (SWPPP) is mandated by the U.S. Environmental Protection Agency (EPA) and the Florida Department of Environmental Protection (FDEP).

Conclusion

In conclusion, address construction controls while designing the project. Then, continue addressing them during all construction and until the site is stabilized. However, continue monitoring the site until it is occupied. Then, if you need any assistance, ESC is here. Further, the firm holds a Florida engineering business license and has a licensed Professional Engineer (P.E.) on staff.

CONCERN WITH SILICA

Sudden Concern with Silica

Increasing Use

Why the sudden concern with silica? Silica is a major component of planet Earth and has been from the beginning of time. As a result, mankind has always been exposed to silica. However, exposure is higher than ever. This is because of increased activity in the construction and industrial areas.

ready-mix concrete plant with sand aka silica — Ready-mix concrete contains silica

Lower Limits

OSHA’s (U.S. Occupational Safety & Health Administration’s, https://www.osha.gov) silica limits are now lower due to the sudden concern with silica a few years ago. To explain, these limits are OSHA’s Permissible Exposure Limits (PELs). Because of the sudden concern with silica, OSHA lowered the PELs for three sectors of workers. Explaining further, those sectors are general industry (29 CFR 1910), maritime industry (29 CFR 1915, 1917, & 1918), and construction (29 CFR 1926).

Disease, the Real Concern with Silica

In the 1930’s, the United States became concerned with silica and the resulting disease silicosis. It is unknown why it suddenly came to the forefront. However, read on for more information on silicosis.

Silica Defined

Silica is a chemical compound, which by definition means there are at least two chemical elements. Firstly, is silicon (Si) which has metallic and non-metallic properties and makes up a large part of the earth’s crust. Secondly, is oxygen (O), which we all know human beings need to survive. Thirdly, comes the chemical reaction where one atom of silicon combines with two atoms of oxygen. Silicon dioxide or SO-2 is the resulting compound. Silica or sand is the common name. Silica makes up quartz, sand, and other substances. Finally, silica occurs in concrete, granite, slate, sandstone, and sandpaper, among other things.

Concern with Silica & Workers

Exposure Routes

Silica can enter the body via three routes. Firstly, it can enter through the skin, known as dermal exposure. Secondly, it can enter through the mouth and digestive system, known as ingestion. Finally, silica can enter the body through the respiratory tract, known as inhalation. Of those three routes, inhalation is the most significant and worst route, because it can end up in the worker’s lungs. As a result, the worker can develop silicosis. Even more important, the greater the exposure the greater the likelihood of silicosis.

Effect on the Body

Silicosis is the respiratory condition that can result from breathing in silica. It is a terrible disease which affects countless workers exposed to silica dust. Here is a link to OSHA’s video on silicosis: https://www.youtube.com/watch?v=HAByIIzQSuU . It is short and to the point. It makes a strong point for avoiding silica exposure.

Testing Workers

ESC has lots of experience testing for silica. The firm has tested at various construction job sites under real and worst case conditions. Typically, this is done where concrete is being cut, milled, or drilled.

ESC has tested at manufacturing plants where granite counter tops are made, concrete products are constructed, roofing shingles are manufactured, and fertilizer is compounded, plus at a college where pottery is made. ESC’s Certified Industrial Hygienist (CIH, http://www.abih.org) works with ESC’s staff level industrial hygienists in designing testing projects, interpreting the results, and preparing the report. More information is available on ESC’s web site.

Conclusion

Contact ESC (https://www.escflorida.com/contact/) for silica testing or more information. ESC has been providing such testing in the industrial hygiene area for over thirty years and has a Certified Industrial Hygienist (CIH). The staff has the credentials and experience to help with all silica testing and consulting needs. ESC strives to respond immediately to all inquiries. Contact ESC today!

Conclusion

Introduction – Construction Pollution

Clearing and developing construction sites disturbs soil and other materials, creating construction pollution. This pollution may be from the site itself, or from the procedures and materials used on the site. Stormwater runoff from rainfall can carry these materials off site. As a result, these materials pollute receiving surface waters. This is because the runoff may be toxic to fish, wildlife, and plants in the receiving water. However, Construction NPDES Stormwater Permits (see our recent blog article at https://www.escflorida.com/construction-stormwater-npdes-permits/) minimize this construction pollution and these impacts.

Suspended Particles

construction pollution in receiving water — Construction pollution in receiving water

Digging, grading, drilling, and dewatering operations create particles from soil, clays, sand, organic matter, and debris. Stormwater runoff picks them up, then they become suspended. As a result, in the receiving surface water these suspended particles block off sunlight from plants and deplete oxygen. Once that occurs, the receiving water can become polluted and devoid of life. However, turbidity measurements determine if the suspended particles are excessive and capable of causing pollution.

Existing Contamination

In comparison to susended particles, construction operations do not cause existing contamination. On the contrary, existing contamination is caused by past usage of the site, legally or illegally, and includes several types of pollution. These types include gasoline, diesel fuel, oil, agricultural materials, or hazardous wastes. The contamination’s location and its concentration may be well documented and the contractor can be forewarned. On the other hand, it may not be and the contractor may discover it after disturbing it. Therefore, the contractor must prepare a plan to handle unknown pollution, including a list of emergency response contractors.

Construction Pollution Chemicals

These chemicals may come from developing the site, working on the equipment, or construction of buildings. For example, they may include, gas, oil, diesel fuel, paint, solvents, grease, fertilizer, pesticides, and sewage, and come from several sources including ordinary use, misuse, storage, leaks, spills, or vandalism.

Stormwater Pollution Prevention Plans

Stormwater Pollution Prevention Plans (aka SWPPPs) prevent construction pollution and eliminate or reduce the impact on receiving waters in several ways. Firstly, they identify operations which will cause pollution. Secondly, they result in a change of the operations. Thirdly, they identify effective controls and provide a schedule for implementation. Most importantly, prepare an effective SWPPP using resources such as the web site of the U.S. Environmental Protection Agency (https://www.epa.gov/npdes/stormwater-discharges-construction-activities).

Conclusion

Stormwater runoff from construction sites does not have to pollute receiving surface waters. If you need any assistance, ESC is here. The firm holds a Florida engineering business license and has a licensed Professional Engineer (P.E.) on staff. ESC’s staff scientists hold bachelors and masters degrees and have over seventy (70) years of combined experience in the stormwater, surface water pollution, and environmental permits field.

Construction stormwater runoff from this site must be controlled to prevent pollution of surface water. — Typical Construction Stormwater Permits Site.

Introduction – Construction NPDES Stormwater Permits
Stormwater Plans (SWPPP)
NPDES Stormwater Permits Application
Erosion & Sediment Controls
Inspections
Stabilization & Permit Termination

Introduction

By design, Construction NPDES Stormwater Permits reduce or eliminate polluted stormwater leaving construction sites. These permits started in the early 1990’s (see one of our previous blogs on environmental permits, https://www.escflorida.com/esc-services/environmental-permits-testing/ ), by the U.S. Environmental Protection Agency (EPA, www.epa.gov/npdes/stormwater-discharges-construction-activities).

Subsequently, the EPA delegated the stormwater NPDES (National Pollutant Discharge Elimination System) permits program to the Florida Department of Environmental Protection (FDEP). As a result, contractors, developers, and owners must obtain coverage under the Construction NPDES Stormwater General Permit and comply with all requirements during construction at a site.

Stormwater Plans (SWPPP)

Prepare Stormwater Pollution Prevention Plans (SWPPP, as explained in our other blog
https://www.escflorida.com/category/npdes-stormwater/ ) before the construction contractor requests coverage under the NPDES General Permit. After that, incorporate the SWPPP elements into the construction plans. To explain further, these SWPPP elements on the plans include sediment and erosion controls.

Components

The following are the main components of SWPPPs:

Site & Project Description
Significant Soil Disturbance Activities & Pollutants
Controls – Erosion & Sediment
Construction Schedule
Site Stabilization
Certifications of Owner, Contractor, & Subcontractors
Inspections

Construction NPDES Stormwater Permits Application

Complete a Notice of Intent form to apply for coverage under the General Permit for construction sites. Mail it to the FDEP with a check for the permit fee. After that, follow up with the FDEP to confirm receipt and coverage under that stormwater permit.

Construction NPDES Stormwater Permits Inspections

To start, install a rain gage, prepare a log book, start monitoring rainfall daily, and record it in the log book. Next, complete inspections weekly and within twenty-four (24) hours of rainfall events of at least ½ inch of rain. To do so, select an inspector with the proper training and qualifications. Then, equip the inspector with an inspection form. Further, require the inspector to fill out the form for each inspection and take pictures of conditions which could pollute stormwater runoff. Next, review each inspection form as soon as possible and sign it as the Site Stormwater Manager. Finally, correct faulty conditions as soon as possible.

Stabilization & Permit Termination

Stabilize the site after completing all significant soil disturbing activities. To explain, seed disturbed areas, sod where needed, and remove temporary controls no longer needed to control erosion and sediment. After that, stop coverage under the NPDES Stormwater Permit by completing a Notice of Termination with the FDEP. The Notice does not require a fee, but you do need to confirm receipt of the Notice by the FDEP.

DON’T PAY TOP DOLLAR FOR MOLD TESTING. . . .

Unless You Want It Done Right!

Now you know the rest of the story! This paper explains why the bargain basement price for mold testing is not necessarily the best. There are reasons why the price is so low. Read on.

Ask Why the Mold Testing Price is So Low

Mold Testing The low price results from several factors. First of all, the personnel may not have the extensive education, training, and certifications that the higher priced testing companies do. Second, they may not have to adhere to a code of ethics of a professional certification board. Third, the types and numbers of samples may be different. Finally, the report and consultation budget may be cut drastically. In conclusion, it is a case of apples and oranges – the two cannot be compared.

Mold Testing Prices

The prices can be significantly different. For example, in our market the low price is $300 for a “mold test” in a small to medium size home or office. The realistic price to test properly is $750 to $1,150. That is quite a difference! It is, but the devil is in the details. First, the low price work is:

2 air spore traps inside & 1 outside
brief report with lab results
scant or no interpretation of results

In comparison, the realistic priced work includes:

2 air spore traps & 2 air culture samples inside + 2 of each outside
2 surface tape samples in AC system
temperature & relative humidity at same 4 air stations
inspection for water intrusion & visible mold
moisture mapping with infrared camera & moisture meter
American Industrial Hygiene Association (AIHA, aiha.org) accredited lab analysis
detailed report with interpretation of results & consultation

That is quite a difference!

Credentials

The low priced company’s staff most likely does not stack up to the realistic priced company. The staff members may not all have 4 year degrees and if they do, the degrees are not necessarily in biology or a related field. Both companies should have Florida licensed Mold Assessors (required by law & officially called Mold-Related Services Assessors). However, the low priced company’s staff will not have a Certified Industrial Hygienist (CIH, American Board of Industrial Hygiene, www.abih.org). The credential is extremely difficult to get but courts recognize CIHs as expert witnesses. That means their work is court defensible which is extremely important in today’s litigious society. No one plans to go to court, but many end up there!

Final Note

ESC is not the low priced company and it does mold testing right. The firm has taken over more than one job from owners who realize they just threw their money away on low priced testing. There is even more information in papers on our web site. They are in our blog section and can be found by clicking on https://www.escflorida.com/esc-services/building-testing/

ASBESTOS POINT COUNTING

Asbestos Point Counting Defined

Point counting is a detailed laboratory method that determines the actual asbestos content of friable building materials. It shows if the content is greater than 1%. The federal asbestos regulations for building renovations and demolitions allow point counting.

The actual regulation is found in Chapter 61.145 of Title 40 of the Code of Federal Regulations, otherwise known as 40 CFR 61.145. Chapter 61 contains the NESHAPs rules (National Emission Standards for Hazardous Air Pollutants). NESHAPs covers quite a few hazardous air pollutants and asbestos is addressed in Subpart M of Chapter 61. NESHAPs is enforced by the U.S. Environmental Protection Agency (EPA, www.epa.gov). State agencies such as the Florida Department of Environmental Protection (www.floridadep.gov) also enforce it.

When to Asbestos Point Count

Do point counting when the material is friable and the initial results are less than 10%. This more detailed procedure tightens the statistics, providing a more accurate concentration.

Options

What are the options? First, assume the initial results are correct and the material contains more than 1% asbestos. Next, abate it prior to disturbance (renovation or demolition). Otherwise, point count it.

Asbestos point counting The decision involves money. The cost of point counting a few samples is a few hundred dollars. But, the cost of abatement is a few thousand dollars. In either case, removing the material can cause an inhalation hazard for the workers and occupants. This is true even for asbestos concentrations less than 1%. That number is a regulatory number, not a safe, no exposure number.

Decision

Like a lot of construction issues, point counting is a business decision. The building owner and occupants make the decision, with the building contractor, licensed asbestos consultant, and licensed asbestos contractor. Consider the potential outcomes. For example, the owner and occupants may say they want it removed properly by a licensed asbestos contractor whatever the concentration is. Alternatively, they may not care about the potential exposure and opt for the building contractor to carefully remove it it if it contains less than 1% asbestos.

So there is a discussion of point counting building materials for asbestos. If you need any assistance, ESC (www.escflorida.com) is here.

Can I Reuse My N-95 Masks?

Introduction

This paper is the fourth in a series on the pandemic disease, COVID-19. The first paper focused on safely reopening your business. The second one concerned face masks, the primary PPE (personal protective equipment). The third paper involved examining the exposure routes. Finally, this one will discuss the reuse of N-95 masks. This has been of great importance during the current pandemic. That is due to shortages of N-95s and the need to protect everybody. Further, health care workers and other front line workers must be protected from infected and asymptomatic carriers of the SARS-CoV-2 novel corona virus.

N-95 Masks Not Designed for Reuse

Do not reuse N-95s. Wear them one time and throw them away. Their paper cloth-like material does not stand up well when washed or disinfected. The filtration can be reduced and put the wearer at risk. The elastic bands and the filter material may become distorted. Then the mask does not seal properly to the face or fit properly. This allows air leakage and defeats the purpose. Also, viruses, bacteria, and physical particles can become trapped on the outside of the filter material and lead to infection when touched.

Short Supply has Forced the Issue

Necessity is the mother of invention! And because the N-95 has come into such demand, we have been forced to explore reuse of these disposable masks. The scientists and regulatory agencies have explored various options and made emergency concessions for the reuse of N-95s. Federal agencies involved include the Center for Disease Control (CDC, www.cdc.gov), Occupational Safety & Health Administration (OSHA, www.osha.gov), and the Food and Drug Administration (FDA, www.fda.gov).

N-95 Masks Reuse Guidelines

The simplest method is to store the N-95 in a closed paper bag and not reuse it until 5 days later. This is not true disinfection but it banks on the virus dying outside of the body, which is typical of most micro-organisms. The CDC identifies the following disinfection methods:

Moist Heat (think autoclave)
Ultra-violet Light
Hydrogen Peroxide

Only trained scientists and medical personnel can use these disinfection procedures. Examine the masks for distortion and damage, then fit test them on personnel. Just remember – when in doubt, throw it out!

As the Virus Turns

That sums up reuse and disinfection at this time. But stay tuned, because new information and data come in every day!

So there is a discussion of reusing N-95s. If you need any assistance, ESC (www.escflorida.com) is here. We have a board Certified Industrial Hygienist (CIH) on staff and have been providing respiratory protection services to our clients for thirty years.

Sewer Discharges Of Industrial Wastewater

Evaluate the Industrial Wastewater

In this paper, we continue our series on environmental engineering. Specifically, we discuss acceptance of your plant’s sewer discharge by the off-site treatment plant. Conversely, this is not about discharges to surface waters, on-site treatment facilities, or ground water.

How do you evaluate your industrial wastewater? Firstly, perform a mass balance calculation. To explain, identify and quantify all chemicals and materials. Basically, mass balance means what goes in must go out. Secondly, list the chemical properties. Finally, determine if the discharge is acceptable. And that is very important. Why? Because the U.S. Environmental Protection Agency (EPA, www.epa.gov) requires it. But the County usually enforces it. How? By using a Sewer Use Ordinance.

Why Worry about Sewer Discharges of Industrial Wastewater?

There are good reasons to worry about your plant’s sewer discharge. For starters, the discharge could be toxic. As a result, it could kill micro-organisms at the treatment plant. What’s more, the discharge might be flammable or explosive. As a result, it could cause a fire or explosion at the plant. Additionally, it could cause the plant’s discharge to pollute surface or ground water. Finally, it could violate the Sewer Use Ordinance. Consequently, your plant could get bad press and be fined.

Will They Know it is from Your Facility?

The County can do sewer discharge tracing. First, they inspect and test the wastewater at lift stations. Second, they use the results to identify one lift station causing the problem. Third, they determine which plants discharge to that lift station. Fourth, they decide which plant is the most likely suspect. Fourth, they knock on your door, ask questions, and test your discharge. It is not that difficult.

Clean It Up

So, before the County comes knocking, see if you need to clean up your wastewater. First, read the Ordinance closely. Second, determine if banned chemicals could be in your discharge. If so, test the discharge. If the results confirm a problem, you are dead in the water, right? No, now explore the following treatment options:

Change the process
Substitute chemicals
Remove hazardous wastes
Pretreat the wastewater
Get input from environmental engineer or County

Next, run a bench scale test on the wastewater after treatment. Good results mean start the treatment. Bad results mean you adjust the treatment, retest, and then start the treatment.

So, there is a discussion of the environmental engineering related to sewer discharges of industrial wastewater! If you need any assistance, ESC (www.escflorida.com) is here.

Environmental Engineering for NPDES Stormwater Pollution Prevention Plan (SWPPP)

Background

So far, we have provided several papers on or related to environmental engineering, which is provided stormwater pollution by environmental consulting firms like ours, Environmental Safety Consultants, Inc. (ESC). We provided information on environmental permits, then went into an overview of environmental engineering. Next, we addressed industrial wastewater and, finally, air emissions control provided by an air engineer. There was also a paper discussing Florida NPDES (National Pollutant Discharge Elimination System) Industrial Stormwater requirements. Now we will discuss the Stormwater Pollution Prevention Plan (SWPPP).

Stormwater Pollution Prevention Plan (SWPPP)

The current paper will discuss environmental engineering required for an SWPPP (Stormwater Pollution Prevention Plan). The regulatory requirements are provided by both the U.S. EPA (Environmental Protection Agency, www.epa.gov) and the FDEP (Florida Department of Environmental Protection, www.floridadep.gov). The requirements discussed herein primarily cover manufacturing and industrial facilities with SIC (Standard Industrial Classification) Codes 21 – 39 with specific exposure to stormwater.

Objective

The objective of the Stormwater Pollution Prevention Plan is self-evident from its name. That is, the SWPPP is prepared by an environmental engineer to prevent pollution of stormwater so it does not discharge and impact receiving waters. Why? Because if it does, it can impair the biological organisms and public health.

Components of Stormwater Pollution Prevention Plan

In preparing the SWPPP, the environmental engineer first identifies the facility and describes its operations, location, and receiving surface waters. Then, information and data are gathered in the following areas to assess the facility’s impact to stormwater:

Topography, runoff, & discharge point(s)
Material inventory, quantities, & exposure
Significant spills or leaks last three years
Non-stormwater discharges
Pollutant sources & specific parameters
Best Management Practices (BMPs) to control pollutants

Based on the results of the preceding, the environmental engineer discusses the findings with the client, then prepares the SWPPP and submits it for review. It is important that the client be able to implement and use the plan to reduce or eliminate pollutants in the facility’s stormwater runoff.

Implementation

The client’s management must endorse the SWPPP and sign it as documentation. A Pollution Prevention Team is formed and identified in the SWPPP. Team members and other personnel receive training. Resources are committed to attain the plan’s objective by implementing the BMPs selected. Visual monitoring of the stormwater discharge is required quarterly and laboratory analysis may be required during the second and fourth years of the five year permit. All records are kept in the SWPPP and, thus, it is a living document.

So there is a discussion of the preparation of an SWPPP by an environmental engineer! If you need any assistance, Environmental Safety Consultants (www.escflorida.com) is here.
