Guidance on Technical Clean Up of Existing Threshold Standards
Project summary: The TRPA 2017 Assessment of 173 existing threshold standards identified 46 standards as overlapping with other standards in the threshold system (TRPA, 2017). In addition to the 46 previously identified overlapping standards, further sources of overlap may exist that were not specifically noted by the Assessment as redundant. Redundancy in threshold standards has the potential to increase the cost of enforcement and monitoring, to confuse the process of implementing standards, and to add uncertainty around the intent of threshold standards and how they contribute to meeting the overall goals of the regulations. Through examination of the existing threshold standards, the Tahoe Science Advisory Council (TSAC) identified five types of overlap: (1) complete overlap, (2) wholly encompassing standards, (3) competing targets, (4), indirect overlap, and (5) policy and management statements that overlap existing standards. This document provides a description those identified types of overlap, and for each one discusses the sources of each, the relative harm caused by the various types, and potential strategies to avoid or resolve that type of overlap.

Implementation of Data Management Structure for Water Quality Threshold Standards
This work order will address the overlap in existing water quality threshold standards, building on the previous work as a framework for moving toward the Council’s vision for a more accountable and science-based data reporting system. The TRPA requests the Council’s assistance in extending and demonstrating the utility of this approach through the implementation of system structure for the water quality threshold category.
The work will consider how to integrate and streamline TRPA’s management systems in the Tahoe Basin. The threshold standards reporting system has historically focused on status and trends, while the Environmental Improvement Program (EIP) reporting system has focused on tracking of actions and dollars. The EIP is the Region’s capital improvement program implemented to advance threshold attainment. More explicitly linking these two reporting structures would improve basin management and promote a more holistic understanding of the goals of management actions and reporting on progress toward achieving those goals.
