Stormwater Management and Nonpoint Source Pollution

These flashcards cover key concepts related to stormwater management, nonpoint source pollution, and the associated practices and monitoring methods.

Stormwater Control Measure (SCM)

Strategies used to manage the quantity and quality of stormwater runoff.

Nonpoint source pollution

Pollution that does not originate from a single point or source, typically caused by rainfall or snowmelt runoff.

Best Management Practices (BMPs)

Proven techniques used during forestry and land management activities to prevent pollution and protect natural resources.

EHS budget

A budget that funds one staff position and education/outreach related to stormwater management.

Impervious area

Land that does not allow water to penetrate, leading to increased runoff; commonly used for stormwater billing.

Deferred maintenance

Repairs or maintenance projects postponed due to budget constraints, usually costing less than $100,000 for utility funding.

Implementation Monitoring

The process of checking if Best Management Practices are being used and are used correctly.

Trend Monitoring

The assessment of whether the use of Best Management Practices is increasing or decreasing over time.

Effectiveness Monitoring

The evaluation of whether Best Management Practices are successfully protecting water and soil.

Culverts

Pipes installed under roads to allow water to flow safely and prevent erosion.

Random Sampling

A method of sampling where sites are chosen randomly, giving each site an equal chance of selection.

Cluster Sampling

A method in which entire groups are chosen (such as counties) and all sites within that group are checked.

Hydrologic modification

Changes made to the natural flow of water, often considered a form of nonpoint source pollution.

Management measures

Strategies developed to control nonpoint source pollution that must comply with EPA technical guidance.

Stormwater utility

A utility that collects fees used to manage stormwater services and infrastructure.

Annual budget

The total amount of money allocated for stormwater services, which is divided to calculate stormwater rates.

Preventive maintenance

Regular inspection and clean-out of stormwater infrastructure to ensure its functionality.

Pollution control strategies

Strategies implemented to prevent or reduce pollution from various sources, emphasizing sustainable practices.

Monitoring

The systematic process of checking and measuring environmental conditions or practices to ensure compliance and effectiveness.

Sampling methods

Various techniques to select sites for evaluation, each with specific pros and cons for time, cost, and accuracy.

Management measures emphasized

Economically achievable strategies that focus on reducing pollution while remaining practical for implementation.

Stormwater utility fee

A charge imposed on property owners based on their impervious area to fund stormwater management operations.
