Ruvalcaba, Cesar <br /> From: Ruvalcaba,Cesar <br /> Sent: Wednesday,July 10,2019 1:54 PM <br /> To: 'DPaul'; Gary delCarlo <br /> Subject: RE: Haley Flying Service- PR0515798 <br /> Paul, <br /> Just a quick note <br /> A. Since the facility has capacity of over 10,000 gallons of petroleum product,it does not qualify for Tier 11 <br /> template.The Tier 11 template was designed for facilities that have less than 10,000 gallons of capacity but have <br /> a single tank that is larger than 5,000 gallons and is meant for self-certification by the facility.The facility, <br /> because of its capacity does not qualify as a Tier 11 facility and requires a certification from a Professional <br /> Engineer(P,E.)for the entire plan. CFR sections 112.7 and 112.8,as well as 112.1 through 112.5. need to be <br /> addressed in the SPCC plan. The regulations can befound here.Sample P.E Certified plan,developed bythe <br /> EPA,can be found here,when we spoke on the phone I thought you were referring to this sample plan. The <br /> sample plan is part of the SPCC Guidance for regional inspectors,which can be found here. <br /> B. For the overfill prevention,here is what the regulations states <br /> Engineer or update each container installation in accordance with good engineering practice to avoid <br /> discharges.You must provide at least one of the following devices: <br /> (i) High liquid level alarms with an audible or visual signal at a constantly attended operation or surveillance <br /> station. In smaller facilities an audible air vent may suffice. <br /> (ii) High liquid level pump cutoff devices set to stop flow at a predetermined container content level. <br /> (iii) Direct audible or code signal communication between the container gauger and the pumping station. <br /> (iv)A fast response system for determining the liquid level of each bulk storage container such as digital <br /> computers, telepulse,or direct vision gauges. If you use this alternative, a person must be present to <br /> monitor gauges and the overall filling of bulk storage containers. <br /> (v)You must regularly test liquid level sensing devices to ensure proper operation. <br /> C. The industry standard is ultimately selected by the certifying engineer. If the SPCC plan states that the facility <br /> will utilize the STI SP001 standard,then the facility must follow the standard as written.The standard has <br /> specific requirements,one of them being using their inspection frequency and inspection list criteria or the <br /> equivalent. <br /> D. If there are no changes to the facility that affect the SPCC plan,the plan can be evaluated every 5 years.Also per <br /> the STI SP-001 inspection frequency by a certified inspector,depending on what category the tanks fall under <br /> and the size of the tanks,the frequency maybe 5, 10 or 20 years. I would recommend stating what category the <br /> tanks fall under,according to the STI SP-001. Depending on the category,additional testing may be required. I <br /> would also recommend giving a reason if an inspection frequency more aggressive than the STI SP-001 standard <br /> is recommended.Are there certain issues or concerns with the tanks that may prompt more frequent <br /> inspections? <br /> Here is what the regulations state for the industry standards- ...You must determine, in accordance with <br /> industry standards,the appropriate qualifications for personnel performing tests and inspections,the <br /> frequency and type of testing and inspections,which take into account container size,configuration, and <br /> design... <br /> t <br />
