Caltha staff are stormwater experts, having worked with stormwater permitting and development of stormwater discharge permit compliance programs and SWPPP since the first stormwater rules were drafted in the 1980s. With this deep foundation in the stormwater rules, Caltha provides expert and cost effective storm water consultant services to clients across the US.

SWPPP, SWPPP Templates and SWPPP Certification

Whether preparing a new SWPPP or revising an existing plan, Caltha provides a choice of three different approaches to provide the level of technical support a facility needs to create a SWPPP that is easy to revise and maintain in the future. Caltha has created State-specific SWPPP templates to match permit requirements for each individual State. Using this “virtual library” of SWPPP templates, we can quickly develop a SWPPP for your facility. Caltha can also provide SWPPP certification and has staff with required certification credentials for most State programs (FAQ: What States require certification? Does my SWPPP or SWP3 need to be certified?).

Stormwater Water Permit Compliance Program
Caltha also maintains a library of stormwater permit compliance plan templates to assist permitted sites in developing and managing their overall compliance program. Compliance plan templates incorporate State-specific requirements, such as inspections, monitoring, reporting and training, and provide an easy way to allocate resources and to develop a compliance tracking system. Caltha also conducts Non Stormwater Discharge Evaluations and provides Non Stormwater Discharge Certifications.
SWPPP Training & Employee Training Development

One of the key compliance elements is development of an Employee Training Program. Based on an individual employees job responsibilities, different level of training may be required, included training certification. Caltha provides stormwater training in a number of flexible formats, including “train the trainer”.

Caltha also offers “real time” web-based training. Trainees log into a webinar format at their own work station and can interact with the trainer in real time. Training sessions are individualized for each facility. Click below to view an example training session.


Storm Water Benchmarks & Stormwater Effluent Limits
Recently, the requirement for sector specific stormwater benchmark monitoring has become a common element in Federal and State general permits. In addition, some types for stormwater discharges are required to meet numeric effluent limits for their stormwater discharge. Caltha assists dischargers in developing pollution prevention programs to meet stormwater quality benchmark concentrations and effluent permit limits.
Storm Water Monitoring & Discharge Monitoring Report
Caltha provides expertise in developing Stormwater Monitoring Plans. Caltha provides the automatic sampling equipment needed to collect samples or can train on-site personnel on sampling techniques, to ensure your facility stays in compliance.
Stormwater Inspections and Comprehensive Facility Compliance Assessment
All permitted sites are required to conduct routine inspections and site compliance inspections. Caltha will conduct these inspections for your facility, or will develop inspection checklists and train your staff to conduct these evaluations. Caltha provides SWPPP Inspection services and erosion and sediment control inspections to general contractors for large and small construction projects.
No Exposure Certification & Conditional Permit Exemption
Many facilities can avoid stormwater permit compliance requirements by meeting the requirements of a “No Exposure Certification”; the specific requirements can change from State to State. In most cases, facilities need to make at least some changes to their operations to meet these requirements. Caltha can provide technical guidance to your facility to identify if you currently meet the certification requirements and if not, what changes would be required.
Spill Prevention & Control, SPCC Plans and 40 CFR 112 Compliance
In addition to SWPPP requirements, some facilities may also need to prepare a Spill Prevention, Control & Countermeasure (SPCC) Plan and comply with the US EPA SPCC Rule. Caltha prepares SPCC Plans, including the new SPCC Template Plan used by smaller, Tier 1 eligable facilities, and assists facilities in developing their SPCC rule compliance program, including SPCC inspections and SPCC training. Caltha also provides SPCC Plans for larger Tier 2 facilities, which require certification by a professional engineer. Caltha also provides technical support in preparing and certifying similar State spill rule plans, such as Preparedness, Prevention & Control(PPC) plans required by the Pennsylvania Department of Environmental Protection, or  Minnesota Spill Billcompliance. (FAQ: What is the difference between a SWPPP and a SPCC Plan? Is my PCC Plan the same as a SPCC Plan?)
