Boiler Basics 101: Emissions Rules & Regulations for San Joaquin Valley APCD

Be sure to read Part I of this series to learn about emissions requirements in the SCAQMD.

In the last edition of Boiler Blog 101, we discussed air permitting rules and regulations in the South Coast Air Quality Management District (SCAQMD). In part II, we will cover the basics of air permitting for boilers in another California district that leads the country in air pollution control; the San Joaquin Valley Air Pollution Control District (SJVAPCD).

The SJVAPCD was founded in 1991 with a mission to improve the health and quality of life for all Valley residents through efficient, effective and entrepreneurial air quality management strategies. The SJVAPCD is made up of eight counties in the Central Valley of California; San Joaquin, Stanislaus, Merced, Madera, Fresno, Kings, Tulare, and Kern.

The rules that have been set forth specifically for boilers, steam generators, and process heaters are outlined below:

  QUALIFYING UNITS NOx LIMIT
Rule 4306 Units Greater Than 5 MMBtu/hr
Units Greater Than 20 MMBtu/hr
15 ppm
9 ppm
Rule 4307 Units 2.0 MMBtu/hr to 5.0 MMBtu/hr 30 ppm
Rule 4308 Units 0.075 MMBtu/hr to Less Than 2.0 MMBtu/hr 20 ppm
ADVANCED EMISSION REDUCTION OPTIONS

Rule 4320

Units Greater Than 5 MMBtu/hr
Units Greater Than 20 MMBtu/hr
9 ppm
7 ppm
*NOx limits listed are standard options for existing gaseous fuel-fired equipment. Enhanced options as well as limits
for new and replacement units will differ. Click each rule to review the full details; certain exemptions may apply.

Starting at the beginning of 2019, the SJVAPCD implemented a new rule titled, Best Available Control Technology (BACT). This rule requires that all new permits meet the lowest NOx limits that have been achieved, regardless of what is mandated. In addition, due to Assembly Bill 617, boiler owners in the SJVAPCD are mandated to meet Best Available Retrofit Control Technology (BARCT) for any existing equipment retrofits. This means that when your boiler needs to be upgraded or replaced, it must meet more stringent NOx limits, which can be as low as 7 ppm.

These rules can be overwhelming, which is why Nationwide Boiler’s AQMD experts are capable and ready to assist you with the permitting process needed for your facility. Furthermore, we can help you reduce NOx to comply with your air emissions regulations. Nationwide Boiler’s CataStak™ SCR system is proven to reduce NOx levels to as low as 2.5 ppm. Contact us today for more details.

Stay tuned for Part III, where we will discuss renting boilers in California.

Building A Culture That Leads To Success

Recent studies show that companies are restructuring their culture, steering away from the competitive work environment with minimal employee recognition, and shifting towards adapting a more team-centric and collaborative working atmosphere.

Nationwide Boiler is proud to say that we have always been a company that encourages team building, and are more than happy to recognize and reward our employees as they excel in their position. In fact, in addition to 5-year length of service awards that are presented at our annual Christmas party, we recognize employees who make a big impact with our ‘Big Kahuna’ award at each quarterly birthday celebration.

IMG_1145.JPGTo encourage camaraderie throughout our company, Nationwide Boiler coordinates multiple events for employees to take part in. This year we have a total of 6 sporting events in the lineup, including soccer, baseball, and college football. The next game we are looking forward to is the Oakland A’s vs. Texas Rangers, and of course, we will be rooting for the A’s! We also coordinate multiple barbeques & dessert socials throughout the year to satisfy our many food lovers and celebrate certain events. Most recently, we held our Independence Day barbeque the week of July 4th. We had grill masters, Larry Day and Michele Tomas, cook up some delicious burgers and hotdogs; while Holly Lepo spoiled us all with her famous and delicious chili, yum! We can’t wait for the next one.

In addition to being sports enthusiasts and foodies, we also like participating and getting in on the action. We recently hosted a bowling lunch at our local bowling alley, Cloverleaf Family Bowl. The group was split into 8 teams (with fun, creative team names), in a competition to win the title of Nationwide Boiler’s 2019 Bowling Champions. In the end, Team Vapor & Team Combustion went head to head, but Team Vapor came out on top. Congratulations to Tim McBride, Phil Blake, Nic Petty, and Sandy Nevels. Let’s see who will take home the title at our next bowling event! 

Nationwide Boiler is blessed to have a team of hard-working, dedicated individuals, which is why we like to create an environment in which they can come to work excited and motivated. Not only does a team focused and collaborative culture increase motivation, it is also proven to improve productivity, encourage creativity, and build trust between employees. And we are living proof of that.

Boiler Basics 101: Common Rental Boilers on the Market

The boiler rental business began over fifty years ago, solving multiple industries’ need for temporary and emergency steam. Nationwide Boiler was at the forefront of the boiler rental industry, starting off with one of the first mobile rental boilers; a 20,000 lb/hr, 300 psig design, O-type package watertube boiler. This boiler was designed for permanent use on a highway-legal open deck trailer, making it a true mobile boiler. This new idea allowed companies to cut capital costs, save time, and be more efficient in their operations. Now, rental boilers are available for small-scale projects to industrial sized applications.

In last month’s edition of Boiler Basics 101, we discussed why rental boilers are a great choice for boiler owners in a variety of industries. To continue the topic, we will now discuss the different types of rental boilers currently on the market.

Trailer-Mounted Boilers

  • - Permanently installed on highway-legal trailers for easy transport by truck
  • - Boilers of various sizes up to 125,000 lb/hr, both saturated and superheated steam
  • - Detachable goosenecks and booster extensions allow for easy removal when space is limited
  • - Not protected from the weather and precautions must be taken for freeze protection (heat tracing and insulation or temporary housing shelters)
  • - Separate feedwater and water treatment systems and other auxiliaries can be provided to support the boiler, as needed

Skid-Mounted Boilers

  • - Shop-assembled package boilers, without any true mobility
  • - Available in capacities up to 250,000 lb/hr
  • - Depending on the size of the boiler, skid-mounted boilers can be transported on a flat-bed trailer, step-deck trailer, or by rail
  • - Cranes and/or forklifts typically required for both loading and offloading
  • - Not protected from the weather and precautions must be taken for freeze protection (heat tracing and insulation or temporary housing shelters)
  • - Separate feedwater and water treatment systems and other auxiliaries can be provided to support the boiler, as needed

Containerized Mobile Boilers

  • - Typically includes a package firetube boiler, installed inside a container and mounted on a chassis for mobility
  • - Ideal for users who need a boiler-only package that is weatherproofed for outdoor operation in the wintertime
  • - Separate feedwater and water treatment systems and other auxiliaries can be provided to support the boiler, as needed

Mobile Boiler Rooms

  • - Complete steam plants, self-contained within enclosed vans, with all equipment required to produce steam:
  •          * Package firetube boiler
  •          * Atmospheric feedwater system
    •          * Water softener
    •          * Chemical injection tank
    •          * Blowdown separator
  • - Typically available in capacities up to 1,000 hp
  • - Weatherproofed and better suited than alternatives for outdoor operation in the wintertime

Mobile Steam Plants

  • - Similar to a mobile boiler room, with all equipment required to produce steam
  • - Equipment is installed on an open, step-deck trailer
  • - Not protected from the weather and precautions must be taken for freeze protection (heat tracing and insulation or temporary housing shelters)

Transportable Steam Plants

    • - Complete steam plant, normally built inside of a standard 20 or 40’ shipping container
    • - Available with either a vertical or a horizontal boiler arrangement depending on requirements
    • - Cranes typically required for both loading and offloading
    • - These systems accommodate less capacity than a mobile boiler room
    • - Popular for overseas and government projects, due to ease of transportation

Each type of rental boiler system explained above has their own unique advantage and may be better fit for one user over another. The requirements of operation, however, are the same: end-users must supply a fuel source (natural gas, #2 oil, propane, or other fuel), electrical power supply, and make-up water. Which type of rental system is best fit for your unique operation?

Nationwide Boiler maintains an inventory inclusive of all types of boilers listed above, ranging in size from 47.5 hp to 200,000 lb/hr. Visit our website to find a complete listing of rental boilers available, and contact a Nationwide Boiler Sales Representative for additional details and pricing. 1-800-227-1966

Discovery ChalleNGe Academy Visits Nationwide Boiler

IMG 9604

Located in Lathrop, CA, the Discovery ChalleNGe Academy is a Community High School run by the California National Guard in partnership with the San Joaquin County Office of Education. Part of the National Guard Youth ChalleNGe Program (NGYCP), the Academy was founded in 1993 to assist students in enhancing life skills, education levels, and employment potential.  This military-style program houses, feeds, and educates 16 to 18-year-old young adults that were unable to complete high school due to varying unfortunate circumstances. The program allows students to earn 65 High School credits while developing leadership, job, and academic skills, while improving self-esteem, pride, and confidence.  


With the school year coming to an end and graduation quickly approaching, The Academy set up a trip for a group of students working to complete their high school credits, and Nationwide Boiler was honored to participate. The goal of this field trip was to educate the graduating class on the many different education, trade, and career opportunities available to them once they step out into the real world.

The first stop of the day was San Jose State University, where they toured the campus and the new $130M recreation center. After experiencing lunch like a college student in the Student Union, they headed north to Nationwide’s shop in Fremont. Upon arrival, the students congregated on the patio to hear a warm welcome from President & CEO, Larry Day, and Vice President, Michele Tomas. The group was then taken on a tour of our 26,000 sq. ft. shop, where day-to-day activities include; boiler maintenance, welding, painting, electrical work, fabrication, equipment assembling, and other technical skills.

Nationwide Boiler’s Shop & Service Managers, Andrew Horne and Michael Rosmando, educated the students on the basics of a boiler system, and walked them through the different trade skills and career opportunities available not just here at Nationwide, but from other companies in similar and varying industries. Many of the students were interested in welding, electrical, and accounting careers. Who knows… we may have just met future Nationwide employees!

At Nationwide Boiler, we feel strongly about training and educating our youth so that we are able to successfully sustain our business and industry for future generations, and we are happy to have had the opportunity to be a part of this inspiring program. Thank you to Todd Robinson and the NGYCP for providing young adults with an opportunity that will help them secure their futures.
