Managing highway runoff is a complex storm water management problem.This research is an input/output field study that specifically examines the hydrologic and water quality benefits of having grass swales with an additional pre-treatment area and incorporation of check dams for managing highway runoff at a Maryland highway. These swales manage the hydrology of the stormwater by increasing the lag time (2-3 hours), reducing the overall average peak (32-44%) and reducing the total runoff volume (4-46%). The overall mass pollutant loads are reduced for TSS (38-62%), nitrate (92-95%), nitrite (54-71%), lead (78-82%), copper (56-70%) and zinc (67-79%). On the other hand, TKN (-120 to 44%), TP (-5 to 40%) and chloride (-61 to -4%) show mass increase. Compared to previous study, swales with check dams do not show any significant improvement over swales without check dams. However, a check dam swale with a pretreatment area has higher reduction of the overall mass pollutants removal for all pollutants except for TSS.

HSSE digitalisation and big data analytics in Oil and Gas industry present a multitude of challenges which includes the inconsistency of work processes in data management, questionable data integrity, high operating cost in managing digital systems, lack of visibility and the mindset shift of users. These challenges have led to the digital transformation journey in PETRONAS. Since PETRONAS embarked on the digitalisation and analytic transformation, numerous value creations have been recorded namely improved HSSE performance, compliance to internal and HSSE regulatory requirements, cost value realization and supporting the United Nations Sustainable Development Goals (UN SDGs). The objective of this paper is to provide strategy guidance in HSSE system digitalisation and data analytics enhancement. The inclusion of digitalisation as one of the focus areas in PETRONAS HSSE Strategy and its supporting blocks in realising the bigger digitalisation agenda can be emulated and/or referenced by industry peers who face similar challenges and are keen to embark on the transformation journey.
